Abstract

이 발명은 시멘트 경화 촉진제에 관한 것임.This invention relates to a cement hardening accelerator.

시멘트 경화 추진제는 NaA1O210~31중량%, Na2CO315~40중량%, CaCO330~35중량% 및 Ca(OH)212~20중량%를 포함함. 액상 시멘트 경화 촉진제는 NaOH 100중량부, Al(OH)3150중량부 피로인산칼륨 0.4중량부, 탄산 칼륨 2중량부를 물 180중량부에 분산 용해시켜 제조함.Cement hardening propellants include 10-31 weight percent NaA1O 2 , 15-40 weight percent Na 2 CO 3 , 30-35 weight percent CaCO 3 and 12-20 weight percent Ca (OH) 2 . Liquid cement hardening accelerator is prepared by dispersing and dissolving 100 parts by weight of NaOH, 150 parts by weight of Al (OH) 3 , 0.4 parts by weight of potassium pyrophosphate, and 2 parts by weight of potassium carbonate in 180 parts by weight of water.
