Ascorbic Acid (vitamin B), which is used as a building material additive, was previously used in high-rise structures, bridges, culverts, and other projects.

Description This is Ascorbic acid Vitamin C Ascorbic acid is a yellow or white crystal or powder. It's a small amount of an acid that has the m.p. between 190-192. It can be easily dissolved in water and alcohol, but it is not soluble well in Ether and Chloroform. In its solid form, it's stable in air. The water solution in it is easy to alter when it encounters air.

Concrete is used with Ascorbic Acid Vitamin C
Ascorbic Acid (vitamin B), can be added to any building material. This is a great water-reducing additive.
Vitamin C A large number strong polar functional groups carboxyl or hydroxyl are present, providing dispersion/flow properties to cement particles.
The cement particles also have polycarboxylic acids that are adsorbed to their surfaces. Carboxylate ions, which make cement particles bear a negative charged, cause electrostatic repulsion and dispersion between them. To make cement fully hydrated, increase the area of contact between cement particles with water.
When cement particles are diffused, water that is not surrounded by condensates can be released. This improves workability and decreases the need for water to mix.
