Title: Neutralization inhibitor for cement
Inventor: TSUYUKI HISAMITSU
IPC: C04B24/12
Filed: 1990-05-11
Abstract: PURPOSE:To capture gaseous carbon dioxide diffused into cement and provide a neutralization inhibitor for the cement excellent in inhibitory action on neutralization of the cement and water-reducing effects by adding an amino acid at a specific weight ratio to the cement. CONSTITUTION:A neutralization inhibitor for cement is produced by adding 0.1-5 pts.wt. amino acid (e.g. glycine or alanine) to 100 pts.wt cement. If the aforementioned neutralization inhibitor is used, salts are formed from calcium, etc., in hydrates such as calcium silicate hydrates in cement in which carboxyl group of the amino acid is hydrated and converted into a form taken into the hydrates. The amino group of the amino acid produces a complex with gaseous carbon dioxide diffused through voids in the cement to capture the gaseous carbon dioxide. Thereby, the neutralization of the cement can be inhibited. Furthermore, since the neutralization inhibitor is excellent in water-reducing effects on the cement and the water cement.ratio is reduced, the neutralization rate of the cement can be synergistically reduced.
