With the increasing awareness about the environment, scarcity of land-fill space and due to its ever increasing cost, waste materials and by-products utilization has become an attractive alternative to disposal. High consumption of natural sources, high amount production of industrial wastes and environmental pollution require obtaining new solutions for a sustainable development. Ordinary Portland cement is recognized as a major construction material throughout the world. Significant research has been going-on in various parts of the world on the subject. Some waste materials and by-products have established their credentials in their usage in cement-based materials and for others research is in progress for exploring the potential applications. This waste, utilization would not only be economical, but may also result in foreign exchange earnings and environmental pollution control. Industrial wastes, such fly ash and silica fume are being used as supplementary cement replacement materials. Currently, there has been an attempt to utilize some amount of bagasse ash, rice husk ash and stone dust.

GENERAL In civil engineering, theoretical knowledge is an application for practical knowledge which is quite different in any field. In civil engineering aspects now-a-days the construction of buildings, industries, residential complexes etc. are more essential. These are included with high expensive of cost, to built up. For that, the no. of techniques are implemented to reduce the cost of construction in all aspects. Economically it is very useful for construction purpose. Replacement of a material with another material is one type of technique which is mostly using in now-a-days to reduce the cost. Replacing of cement (or) coarse aggregates (or) fine aggregates with other materials which is made to be an economical NEED OF THE PRESENT PROJECT Cement is the most costlier and energy intensive component of concrete. The unit cost of concrete can be reduced by partial replacement of cement with SCBA, RHA & SD. Concrete making with conventional material is becoming costlier day by day. More over concrete suffers little resistance to cracking. These problems may overcome by inclusion of these admixtures into concrete MATERIALS USED Cement The most common cement used is ordinary Portland cement. Out of the total production, ordinary Portland cement accounts for about percent. Many tests were conducted to cement (53 Grade) some of them are consistency tests, setting tests, soundness tests, etc Fine Aggregate Locally available free of debris and nearby river bed sand from ferri river is used as fine aggregate. The sand particles should also pack to give minimum void ratio, higher voids content leads to requirement of more mixing water. In the present study the sand conforms to zone II as per the Indian standards Coarse Aggregate The crushed aggregates used were 20mm nominal maximum size and are tested as per Indian standards and results are within the permissible limit Water Water available in the college campus conforming to the requirements of water for concreting and curing as per IS: INTRODUCTION OF ADMIXTURES From these by-products in concrete production brings a positive effects to the environment which reduces waste disposals. Since we reduce the cement production also. AGRO INDUSTRIAL MINERAL ADMIXTURES is a factory which reduces the emissions generated by the disposal of all by-products editor@iaeme.com

3 A Comprehensive Study On Partial Replacement of Cement with Sugarcane Bagasse Ash, Rice Husk Ash & Stone Dust Due to these admixtures there is a change in concrete in both physical and chemical conditions. The physical effects are the mixture which depends on size, shape, and textures of particle. The chemical effects are capability of providing aluminous compounds which react chemically in the presence of water like calcium hydroxide etc., the two scientists namely GOLDMAN &BENTUR Said that by mixture of these admixtures there is a physical effects are more than the chemical effects. The admixtures which are used for the replacement of cement are as follows. SUGARCANE BAGASSE ASH RICE HUSK ASH STONE DUST (or) QUARRY DUST 3. PROPERTIES OF MATERIALS 3.1. GENERAL The materials used in the experimental work namely cement, Bagasse ash, Rice husk ash, Stone dust, fine aggregates and coarse aggregate have been in laboratory for use in mix designs. The details are present below Cement [IS: ] Ordinary Portland cement of 53 grade was used in this project. The general standard values of different tests on cement described below. Table 1 SL.NO.

The compressive strength is determined by the ratio of failure load to the cross sectional area of the specimen. The compressive strength of concrete has been evaluated by testing four cubes of size 15 cm x 15 cm x 15 cm, the testing procedure is shown in fig. (p) & fig. (q). The results are tabulated in table-7 and the graph is drawn, shown in graph editor@iaeme.com

CONCLUSIONS It has been observed that by the incorporation of SCBA, RHA & SD as a partial replacement to cement in plain concrete, increases workability when compared to workability with reference to concrete made without admixtures. The mix proportion of 6% replacement of cement with SCBA (2%), RHA (2%) & SD (2%) showed good properties like Compressive and Tensile strength. It has been observed that cement replacement using SCBA, RHA & SD can go up to 8% safely through strength values are less compared to 2% replacement of cement and is most economically feasible. 9. SCOPE FOR FURTHER INVESTIGATION Experiments can be encouraged with different proportions of replacement of cement in terms of other mineral and chemical admixtures. Durability aspects can also be investigated with different proportions of admixtures. Studies can be made when the mixes are exposed to high temperatures.
