So we need to look for ways to reduce the use of water in concrete in most economic way possible. We also want concrete to gain its ultimate strength earlier to reduce the overall requirement of water. Plasticizers and Superplasticizers are used to reduce the water requirement in the concrete. The use of these admixtures not only reduces the water content of the concrete but also gives higher early strengths and higher ultimate strengths. The available Plasticizers and Superplasticizers in the market are costly and hence cannot be used for smaller project as they will make the project uneconomical. This project work is conducted to find better alternatives to these available costly Superplasticizers. This report is about the project work which includes the study of effect of chemicals as Superplasticizers on various properties of the concrete. The study of different chemicals used as Superplasticizers for concrete and their comparison with the normal concrete. There are two different chemicals taken for the project work. The chemicals are added in different proportions of 0.25%, 0.5%, 0.75% and 1% of the weight of cement. The concrete cubes of M25 grade were prepared. The normal cubes and the cubes with the chemical admixture were tested. Then the behavior of the concrete is noticed to checks how the changes made in the properties with the addition of the different proportion of the chemicals. The reduction in water content is also checked with the addition of the different proportion of the chemical admixtures. The properties like consistency, initial setting time, slump cone test, water absorption test and compressive strength tests were tested. The project work also include the study of the properties of the chemicals used for the project work .It comprises of different tests for different building material such as sand, aggregates (coarse & fine aggregates), concrete and cement used for the completion of the project. The aim of the project is to find a better substitute to the costly super plasticizers available in the market and make the each project economical.

The study of different chemicals used for waterproofing of concrete and their comparison with the normal concrete. The study also includes the properties of Ultratech Weatherplus cement concrete and the various admixtures used for the water proofing technique. It comprises of different test for different building material such as aggregates (coarse & fine aggregates), concrete and cement. The report also includes study of water absorption property of different types of cement concrete. The study also includes the design of concrete mix and the various tests of the materials used for the project work. Index Terms Water Proofing, Concrete, Water Repellent Chemicals, Ultratech Weatherplus Cement, SBR, Polyurea.
