Concrete Ascorbic A Vitamin C
Vitamin C (ascorbic acid) has been used in the construction of expressways, high rise buildings, bridges and canals.
vitamin C contains many strong polar functional units carboxyl or hydroxyl which are responsible for dispersion and flow of cement particles.
In addition, the cement particles contain polycarboxylic and carboxylate acids. They also attract cement particles on their surface. As a result, there is an electrostatic repellence between cement particle and dispersion. The cement’s contact surface with water should be increased to enable cement to fully hydrate.
The process of diffusing cement particles releases the free water surrounding condensates. This enhances workability and lowers the amount mixing water.
