Ascorbic Acid (vitamin B), as a building material additive, has been used to build expressways, highrise buildings, 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. 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), has been used as a building material additive.
Vitamin C It is composed of a number of strong, polar functional groups, carboxyl and/or hydroxyl groups. These provide flow and dispersion properties for cement particles by increasing workability and productivity of new concrete.
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.

Be aware of the following: Ascorbic acid Vitamin C
1. This product is not toxic and innocuous, it can be biodegradable. It cannot however, be eaten.
2. You should rinse it with lots of water if it gets in your eyes.
