Study on alccofine based high performance concrete

Abstract

In this present scenario of construction practice, new materials are being used as additive to the High Performance Concrete. Alccofine 1203 is one of such additive which proposed to use, in order to increase the compressive strength and durability of concrete. Alccofine 1203 is primarily composed of low calcium silicates which is processed and obtained through controlled particle size distribution (PSD). When compared to cement, the particle size distribution and specific gravity of Alccofine 1203 is higher and lower respectively, thus making more suitable as an additive to cement. In this thesies, it is proposed to study the Alccofine based high performance concrete with various proportions. M50 grade of concrete is planned to study by their mechanical properties such as compressive strength, flexural strength, elastic modulus of concrete and other durability properties. For all the tests, standard experiments are followed to determine the properties as per Indian standards. The results are presented and discussed. It is observed that 10% Alccofine added with the cement is giving increase in strength.
