Wate Latex paint (WLP) contribute ignificantly toward liquid wate and it dipoal ha become a major concern for environment. Thi project focue on utainable development through the recycling of wate latex paint by incorporating in concrete. It alo aim at determination and comparion of trength characteritic of normal tructural concrete and by incorporating different percentage of WLP by partially replacing required water content. From the laboratory tet reult it ha found that introduction of wate latex paint can improve ome key propertie of concrete uch a workability, durability, flexural trength etc. Keyword- Concrete, Recycling, Wate Latex Paint, Water content I. INTRODUCTION Solid, gaeou or liquid wate, ingly or combined can create eriou problem for human and the environment if they are not treated, tranported and managed afely. Latex paint can be highly toxic to the environment and alo have advere effect on health if not dipoed properly. It not only harm aquatic life, wildlife but pollute groundwater alo, if dumped on the ground. Thi tudy i focued on dicovering a uitable re-ue option to reduce dipoal and pollution problem emanating from wate latex paint and to develop a profitable building material from the wate latex paint. Latex paint i a water-baed diperion containing rein, olvent, pigment, and additive. It include all paint that ue ynthetic polymer uch a poly acrylic, poly vinyl acrylic (PVA), tyrene acrylic, etc. a binder. Wherea recycled latex paint i made primarily with leftover which are collected from reident, painting contractor and other paint uer. The main aim of the tudy i to produce a concrete mix capable of maintaining or improving the propertie of the hardened concrete while increaing the efficiency of the contruction proce. It i etablihed that wate latex and acrylic baed paint i a uitable additive to Concrete, reult in maintaining trength and improving workability, providing a viable ubtitute to tandard chemical admixture currently ued to achieve comparable reult []. Increaed water content i required to enure that the wate paint i ditributed evenly within the concrete mix, which maintain the compreive trength without the addition of exceive air content. A concrete mix deign of :.44: 3.3:.5 i elected and a number of tet are conducted to evaluate the propertie of variou freh and hardened concrete when mixed with an optimum doage of the wate paint. Detailed tudy of propertie of wate latex paint concrete focued upon workability, compreive trength, tenile trength etc. were tudied to ae the hardened propertie of the concrete. II. OBJECTIVE The objective of thi paper i to determine the trength characteritic of recycled WLP for application in normal trength tructural concrete, which will give a better undertanding on the propertie of concrete with recycled WLP. It aim to conduct a reearch on recycled WLP and contruct the concrete pecimen by uing different percentage of recycled WLP. Laboratory teting of normal trength concrete with recycled WLP i alo to be performed. The analyi and comparion of the reult are reported for further reearch. III. METHODOLOGY In thi tudy wate paint i ued a a partial replacement for mixing water in concrete. The teting wa carried out in two tage, initially without the addition of WLP and in next tage with the addition of wate latex paint. Variou laboratory tet method are conducted to check the ability of wate latex paint 69 P a g e

2 International Journal of Engineering Reearch and Application (IJERA) ISSN: Trend and Recent Advance in Civil Engineering (TRACE- 4th-5th January 4) to replace tandard chemical admixture preently ued in concrete to ome extent and alo to confirm the trength propertie of the new mix. Reult in the variou propertie of freh and hardened latex paint will verify the potential of wate paint a a ucceful cementitiou admixture. Inference are gathered on concrete compreive trength, tenile flexural trength, pread (workability) etc. IV. EXPERIMENTAL MATERIALS 4. Cement Ordinary Portland pozzolona cement (53 Grade) wa ued for the entire pecimen. The pecific gravity of cement wa found in the laboratory by uing Pyconometer and other acceorie and obtained the value a Fine Aggregate River and wa ued a fine aggregate for all pecimen. The pecific gravity of fine aggregate ued for concrete wa determined and found to be.65. The and ued for cating wa ieved paing through IS 6µ Sieve and retaining on IS 3µ ieve. 4.3 Coare Aggregate The coare aggregate ued in the mix are hand broken granite tone obtained from local quarrie. Size of aggregate ued for all pecimen wa mm. The Specific gravity of coare aggregate wa determined and found to be Recycled Latex Paint Recycled latex paint i made from unued latex paint collected from houehold, government, and painting contractor. New material are added to improve the paint conitency and to make tandard colour. V. EXPERIMENTAL PROCEDURE 5.Preparation of Concrete Mix by Blending WLP The control mixture i prepared by the following procedure: Water and WLP are manually mixed, aturated and urface-dried coare aggregate are premixed with part of the mixing water (containing WLP), fine aggregate and cementitiou material are then added and mixing reumed for minute with the remaining mixing water and chemical admixture being added over the firt minute of mixing. After a minute ret period, 3 minute mixing equence i conducted. Setting time of cement ha been determined. The following tet are conducted over the prepared pecimen. Acid attack Tet i modified in thi invetigation for teting of concrete pecimen ubjected to ulphuric acid at the age of 8. Leaching tet were conducted on three replicate concrete pecimen ubjected to 3 freezing-and-thawing cycle for mixture incorporating %, 5%, 5%, and 5% WLP a partial replacement for mixing water. Pour dry concrete mix into a uitable container for the amount of mix to be made, replace up to 5 percent of the water with any of the latex paint. A control concrete mixture with a watercement ratio (w/c) of.5 and mixture with imilar (w + WLP)/c incorporating 5%, 5% and 5 % of WLP a partial replacement by ma of mixing water are prepared. Mix the paint well before combining it with the concrete. Add the ret of the water and percent more to make a wetter mix than normal. Make ure that the paint i mixed well, until there are no dry pocket or viible patche of paint. Apply the well mixed concrete and the latex paint mixture and allow drying for the recommended time. There will be le hrinkage of the concrete due to the latex paint filling in more of the air pocket. 5.Preparation of Tet Specimen Concrete mainly contain cement, water, fine aggregate and coare aggregate. Wherea, control concrete, in thi context mean replacement of 5%, 5% and 5% of the mixing water with recyclable latex paint. Variou tet are conducted on controlled concrete and tandard concrete by preparing tet pecimen a follow.

CONCLUSION Baed on limited experimental invetigation concerning the trength propertie of tructural element, the following obervation are made regarding the influence of partially replaced wate latex paint a) Compreive trength increaed with WLP addition giving acceptable reult upto 5% partial replacement of water b) The plit tenile trength alo ignificantly increaed a the partial replacement of WLP increae in the conventional concrete tructural element. c) The flexural trength of concrete increaed with addition of WLP and highet value i obtained at 5% partial replacement of mixing water. Flexural behavior of beam indicate crack appear comparatively at a higher rate of loading in 5% partial replacement of WLP than in % WLP addition. d) From the lump tet reult, it i oberved that application of WLP a an admixture improve the workability of concrete. e) Initial etting time of concrete wa not reduced due to WLP addition, wherea the final etting i lightly reduced, which i perceived a an advantage. f) The durability of concrete i alo ignificantly enhanced due to WLP addition, and no ignificant emiion of toxic ubtance i detected in leaching tet of WLP concrete pecimen. g) Environmental effect from wate and dipoal problem of wate can be reduced. h) The primary ingredient of paint and their poible influence on the characteritic propertie of cementitiou material alo hould be invetigated. i) The dipoal problem of tructure uing WLP after their life pan hould be ubjected to further reearch.
