Concrete Technology - Sika

The first step in optimizing concrete is to recognize that concrete is no longer simply cementitious materials, aggregates and water. It is a high performance material with not just four, but seven essentials - consisting of water, cementitious material, sand, gravel, chemical admixtures, additives and fiber reinforcement.

Concrete Admixtures - Types and Functions - Cement Concrete

Concrete admixtures have various functions and they are as follows: (a) To increase the rate of strength development at early ages - calcium chloride is the most widely used accelerator, (b) To retard the initial setting time while pumping concrete over a long distance, (c To increase the workability without changing the water content

Use of Water Reducers, Retarders, and Superplasticizer

Other benefit of using WRA is that higher concrete density is achieved which makes the concrete less permeable and have a higher durability. Retarding admixtures. The use of this admixture is defined in ASTM C494. There are two kinds of retarders, defined as Type B (Retarding Admixtures) and Type D (Water Reducing and Retarding Admixtures).

Concrete Admixture (Chemical and Mineral Admixtures

CONCRETE ADMIXTURES • Admixtures are material other than cement, aggregates & water that are added to concrete either before or during mixing to alter its properties & performance in fresh (workability, setting time etc) and hardened state (strength, durability etc.) Concrete admixtures are generally divided into 2 types i.e., 1.
