Punjab Technical University, Jalandhar, Punjab, India Dr. Jagbir Singh Associate Professor, Department of Civil Engineering, GNDEC, Ludhiana, India Dr. Rajesh Kumar Professor and Head, Department of Civil Engineering, CCET, Chandigarh, India ABSTRACT The use of recycled aggregates (RA) for structural concrete in construction, to the maximum possible limit, is becoming a necessity more than a desire. One such mechanical property, shear resistance of recycled aggregate concrete (RAC) beams is an intensive area of research. Three parameters i.e. compressive strength, percentage of tension steel and shear span to depth ratio were considered. An attempt has been made to study shear strength of RA concrete beams of M 20 grade with 25 and 50 % weight replacement of natural aggregate (NA) with recycled aggregate (RA) for different shear span to depth ratios a/d = 1.5, 2.5 and 3.5 with 1 % tension steel without shear reinforcement and compare the test results with the available shear models. Seven shear models for comparison were considered namely ACI 318, Canadian Standard, IS Code, CEB-FIP Model, Zsutty Equation, Bazant Equation and Okamura and Higai equation. The results revealed that Shear capacity of a RAC beams with 25 and 50 % RA is comparable, or sometimes superior, to that of a controlled beam made of conventional concrete. Equations proposed by Zsutty and Bazant gave relatively more accurate results in terms of the similar pattern as compared to other models but still considerably lower values as compared to experimental results and hence these models can be used effectively for recycled aggregare concrete also.

Continuous efforts are being made to improve the mechanical properties of RAC as compared to normal aggregate concrete. There are several modes of failure in concrete structural members. Due to the fragility of concrete structures, shear failure is one of the most important and undesirable modes of failure. Shear strength of concrete depends significantly on the ability of the coarse aggregate to resist shearing stresses. RA used is relatively weaker than NA in most cases and yielded reduced shear strength. Shear force is present in beams at sections where there is a change in bending moment along the span. It is equal to the rate of change of bending moment. An exact analysis of shear strength in reinforced concrete beam is quite complex. The reuse of hardened concrete as aggregate is a proven technology - it can be crushed and reused as a partial replacement for natural aggregate in new concrete construction. The use of 100% recycled coarse aggregate in concrete, unless carefully managed and controlled, is likely to have a negative influence on most concrete properties but literature shows that the compressive strength of concrete up to 50 % RA have strength in close proximity to that of normal concrete. 2. EXPERIMENTAL PROGRAMME Nine reinforced concrete beams were cast and tested, under two point loading for varying shear span to effective depth ratio (a/d). The section of all the beams (width thickness) was kept constant at mm. To investigate the effect of shear spanto-depth ratio, a/d values of 1.5, 2.5, and 3.5 were selected to cover short, intermediate, and long beams. Accordingly the overall length of the beam specimens was varied in the range 1.60 m, 2.20 m and 2.70 m. The percentage of tension 100A reinforcement, st was kept constant 1.1%. Concrete of grade M 20 having bd nominal crushing strength of 20 N/ mm 2 was used for investigation. Keeping in view the lower compressive strength of concrete with more than 50 % of recycled aggregates, concrete mix with more than 50 % recycled aggregates were not taken in to account for shear investigations and only 25 and 50 % weight replacement of natural aggregate with recycled aggregate for M 20 grade was considered. Controlled beams with 100 % natural aggregates (0 % RA) were also cast and tested to compare the results. The details of the specimens for shear test are listed in the Table 1 below: editor@iaeme.com

The materials, in general, confirmed to the specification laid down in the relevant Indian Standard Codes. Ordinary Portland Cement of 53 Grade from a single source with specific gravity 3.14, confirming to IS: was used. A low-calcium fly ash obtained from the combined fields of the electrostatic precipitator of the thermal power plants with specific gravity 2.24 was used. Locally available natural river sand having a specific gravity of 2.58, water absorption of 1.10% and a fineness modulus of 2.68 was used as fine aggregate. Portable water free from any harmful amounts of oils, alkalis, sugars, salts and organic materials was used for proportioning and curing of editor@iaeme.com

4 Experimental Study on Shear Behavior of Reinforced Recycled Aggregate Concrete Beams concrete. Deformed steel bars of 10 mm and 12 mm nominal diameters and with nominal yield strength of 423 MPa were used as tension reinforcement in the beams. Shear reinforcement in the form of stirrups were not provided. All the steel reinforcement bars confirmed to IS 1786: Two types of coarse aggregates named Natural Aggregate (NA) and recycled aggregates (RA) were used in the RAC mixes. Locally available crushed granite having a specific gravity of 2.70 was used as NA. RA was derived from the tested concrete cubes in the laboratory that contained well-graded crushed granite stone. Specific gravity of RA was found 2.48, which is lower than NA. The concrete cubes were crushed manually to the specified size using a hammer and gradation was achieved through sieving of RA. The maximum size of coarse aggregate used was 20 mm in both recycled and natural aggregate concrete Concrete Mix Design The concrete mix M 20 of characteristic strength of 20 N/ mm 2 with constant water to cement ratio (w/c) 0.5 was used in this investigation which is commonly used in construction of structural members. The mix design was done according to the IS: and numerous trial mixes were conducted to obtain the optimum mix. Once the optimum mix was determined, it was used to produce concrete with 25% and 50% recycled coarse aggregate by weight replacement of natural coarse aggregate. Due to the higher water absorption capacity of RA as compared to natural aggregate, both the aggregates are maintained at saturated surface dry (SSD) conditions before mixing operations. Fly ash was used as 25% by weight replacement of cement to achieve proper workability of the mix. The details of optimum mix are given in Table 2. Mix Mix proportion by weight Table 2: Mix proportion for optimum mix Fly Ash % Cement Constituents (kg/m 3 ) Fly Ash Sand Aggregates W/C ratio M 20 1:1.5: Instrumentation and Testing Procedure In the present study beams were cast in steel forms with the tension reinforcement near the bottom. No stirrups (shear reinforcement) were provided in the beams. Lifting lugs were also provided for transporting the finished specimen to the test platform. The concrete was compacted with needle vibrator. Form work was removed after 48 hours. The beams were cured with wet hessian and sand for 28 days. To facilitate the tracing of cracks, the beams were distempered white prior to testing. For investigation of the shear behavior, beams designed only for adequate flexural strength and without any web reinforcement were tested under monotonically increasing loads in a four point loading configuration to study the shear failure mechanism. The beam specimens were tested as simply supported beam by using a manually operated hydraulic Jack that applied load gradually on the mid-span of the beam specimens until shear failure which pre-empted flexural failure.

The arrangement of 4 LVDT s attached diagonally in pairs on the side-face of the beams in the shear zone were done to detect diagonal cracking.

6 Experimental Study on Shear Behavior of Reinforced Recycled Aggregate Concrete Beams 3. DISCUSSION ON TEST RESULTS The cracking and ultimate shear stress calculations of RAC beams are presented in Table 3. Graphical representation of comparison of cracking and ultimate shear strength of RAC beams with controlled (NAC) beams is shown in Figs. 3 and 4. In the case of short beams (a/d < 2.5), a very significant amount of additional loading can be resisted by the reinforced recycled aggregate concrete beams beyond the formation of a first diagonal crack before ultimate failure in shear-compression occurs. This redistribution of stresses in short beams takes place because of the relatively short distance between the supports and the applied loads, and is evidenced by the large spread in magnitude that exists between V cr and V u (in short beams, the redistribution of stresses is due to the transferring of the applied loads directly to the supports by arch action). Conversely, the failure mode in long beams (a/d 2.5) is in diagonal tension with the formation and propagation of the first fully developed inclined crack. As a/d increases from 2.5 to 3.5, this failure mode becomes very sudden in RAC beams as total shear failure occurs almost immediately after the formation of a first major diagonal cracking.

At a/d ratio 1.5, the first cracking load as well as the ultimate diagonal shear load was observed to be almost double than that at a/d ratio 2.5 and 3.5. At a/d ratios 3.5 and concrete with 50 % of RA, the failure was observed to be sudden as compared to failure pattern observed for lower a/d ratio 1.5. Crack width for RAC beams was wider as compared to control beam due to weak bonding of RA with new concrete. Results also showed that the shear capacity of a RAC beams with 25 and 50 % RA is comparable, or sometimes superior, to that of a controlled beam made of conventional concrete editor@iaeme.com

8 Experimental Study on Shear Behavior of Reinforced Recycled Aggregate Concrete Beams 4. COMPARISON OF EXPERIMENTAL SHEAR RESULTS OF RAC BEAMS WITH AVAILABLE SHEAR MODELS Based on experimental observations, different researchers have developed different equations for the prediction of shear capacity of the NAC rectangular beams. Shear models used for NAC beams have been used here to predict shear strength of RAC beams because till date no specific code and models for RAC is formulated. Table 4 presents the experimental and predicted shear strength values of all the test beams with different percentage of recycled aggregate and with different a/d ratios. It can be observed that regardless of the a/d ratio, all the empirical equations gave a conservative estimate of the actual ultimate shear strength for all the replacement level of recycled aggregate of RAC beams. For all the models used to calculate V c, the calculated strength values became more conservative as the a/d ratio decreases. T C Zsutty collected the test data of about 200 beams from different responsible sources and developed equations by combining the techniques of dimensional and statistical regression analysis for the prediction of shear strength of longitudinally reinforced beams.

Almost similar trend of normal aggregate concrete members is followed by RAC beams. There is no negative impact of the replacement of 25 and 50 % RA. Analytical values and experimental results revealed that a/d ratio significantly affects the shear capacity of recycled aggregate concrete beams. Most of the equations are under estimating the shear capacity at lower a/d ratios. When the a/d ratio is less than 1.5, strut action prevails and the shear resistance is very high. For a/d ratio 1.5 the experimental values showed remarkable increase in shear strength compared to various design models. Only predicted shear capacity using Zsutty and Bazant Equation had followed the same pattern for all the three a/d ratios but the values were still lower than experimental values for all concrete mixes. For a/d ratios 2.5 and 3.5 almost all the models followed the same trend but with quite lower values. 5. CONCLUSION Shear capacity of a RAC beams with 25 and 50 % RA is comparable, or sometimes superior, to that of a controlled beam made of conventional concrete. For a/d ratio 1.5, there is sharp increase (almost double) in shear capacity of RAC beams as compared to a/d ratio 2.5 and 3.5. There is not much difference in the shear capacity of RAC beams for a/d ratio 2.5 and 3.5. For higher a/d ratio 3.5, sudden shear failure of RAC beams were observed as compared with a/d ratio 1.5. There is less difference between first crack load and ultimate shear load for a/d ratio 3.5. Crack width for RAC beams was wider as compared to control beam due to weak bonding of RA with new concrete. ACI as well as IS code give overly conservative shear capacity predictions of recycled aggregate concrete beams without web reinforcement at all a/d ratios because ACI code presented a formula for the prediction of shear cracking load in 1963, which was developed by the linear regression based on thousands of beam test results subjected to UDL only editor@iaeme.com

11 Pinal C. Khergamwala, Dr. Jagbir Singh and Dr. Rajesh Kumar The Canadian code considered only compressive strength of concrete. It has not taken into account the effect of shear span to depth ratio and longitudinal tension reinforcement on shear strength of beams. The shear resistance of RAC member predicted based on Canadian code underestimates the actual shear capacity of member at all a/d ratios. Shear capacity of the RAC members predicted based on CEB-FIP model and Okamura- Higai equation showed conservative values at all a/d ratios. Zsutty equation is more appropriate and simple to predict the shear strength of both shorter and long beams as it takes into account size effect and longitudinal steel effect for RAC beams also. The Bazant equation has better agreement with the test data. In this equation five parameters (fc, ρ, a,d, d and da) are correlated with ultimate shear strength of rectangular beams, especially the effect of aggregate size, which plays very important role in the shear strength.
