Studies on Durability Factors of Self Compacting Concrete

摘要

The demand for high strength self compacting concrete is growing up today due to the increase of high rise structures across the globe because of its durability and ease of its place ability. It is very important to study its durability properties as it effects on economy, serviceability and maintenance, it is well known that the properties of concrete are affected by cementitious matrix, aggregate and the transition zone between the two phases. Reducing water powder ratio and addition of pozollona admixtures like Fly ash and Microsilica are often used to modify the micro structure of the matrix and to optimize the transition zone. An attempt was made to study the durability factors of High Strength Self Compacting Concrete Mixes. Durability properties have been established by exposing the concrete to Acidic and Suplhate medium.
