Ascorbic Acid (vitamin B), used as an admixture in building materials, such as expressways and high-rise buildings.
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, chloroform or any other organic solvent. It remains stable in air when it is solid. 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), an additive to building materials, has been used to build expressways, highrise buildings, bridges, culverts, and other projects.
Vitamin C
contains strong polar functional groups such as carboxyl and hydrochl groups. These provide flow and dispersion properties for 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.
