▎ 摘  要

NOVELTY - Anti-cracking slag soil building block comprises 45-55 pts. wt. building slag, 14-17 pts. wt. cement, 2-4 pts. wt. sodium silicate, 3-7 pts. wt. gypsum powder, 5-10 pts. wt. mineral powder, 5-10 pts. wt. fly ash, 4-6 pts. wt. water, 0.4-0.6 pts. wt. water reducing agent, 0.4-0.6 pts. wt. polypropylene fiber, 0.5-1.5 pts. wt. magnesium oxide expansion agent, 0.3-0.8 pts. wt. calcium oxide expansion agent, 1.5-2.5 pts. wt. redispersible latex powder, 0.8-1.2 pts. wt. modified silica, and 0.4-0.6 pts. wt. metal complexing agent. The modified silica is obtained by treating silica with methyl acrylate, ethylenediamine, graphene oxide, and graphene. USE - Anti-cracking slag soil building block. ADVANTAGE - The slag soil building block has high compression strength, anti-cracking ability, and anti-seepage ability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing anti-cracking slag soil building block.
