▎ 摘　　要

NOVELTY - A cement is prepared using 90-110 pts. wt. silicate cement clinker, 10-20 pts. wt. gypsum powder, 5-15 pts. wt. fly ash, 5-15 pts. wt. slag, 8-12 pts. wt. granular biomass combustion waste material, 4-6 pts. wt. phase-change temperature control material, 8-12 pts. wt. tourmaline powder, 8-12 pts. wt. bentonite, 6-10 pts. wt. redispersible emulsion powder, 3-8 pts. wt. magnesium oxide expansion agent, and 1-5 pts. wt. solid polycarboxylic acid water reducing agent. USE - Cement. ADVANTAGE - The cement has high compressive strength, high crack resistance, high frost resistance, and good comprehensive performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for method of preparing cement, which involves uniformly mixing silicate cement clinker, gypsum powder, fly ash, slag, granular biomass combustion waste material, phase-change temperature control material, tourmaline powder, bentonite, redispersible emulsion powder, magnesium oxide expansion agent, and solid polycarboxylic acid water reducing agent.
