PRODUTO ENDURECIDO SIMILAR A CONCRETO,COMPOSICAO DE ENDURECIMENTO RAPIDO,E PRODUTO DE CIMENTO ARMAZENAVEL |
摘要 |
<p>Rapid-setting compositions based on MgO and Al(H2PO4)3 and having at least a ten-minute working time, and thus suitable for mortars and road patching, form concrete-like products having increased compressive strength when fly ash is present. Fly ash reacts with aluminum phosphate to form a cementitous composition whose compressive strength is the cause of the strength increase observed in the MgO/Al(H2PO4)3 reaction product.</p> |
