城乡建筑业的发展和日益严重的环境污染,迫使人们对建筑材料提出了更新更经济的要求。双灰粉正是在这种情况下应运而生的。由于它具有传统水泥的胶结特性,因而被人们誉为水泥的“弟弟”。如果在砌筑砂浆或低标号混凝土中使厂时,可全部或部分替代水泥。双灰粉以生石灰(电石厂、糖厂、碱厂的工业废碴亦可替代)、粉煤灰(工业炉碴、煤矸石、废砖瓦亦可替代)为主要原料,同时加入适当的催化剂、安定剂、调凝剂,经混合
The development of the urban and rural construction industry and the increasingly serious environmental pollution have forced people to put forward newer and more economical requirements for building materials. Double gray powder came into being in this situation. Because it has the cementitious properties of traditional cement, it has been hailed as the “brother” of cement. If the factory is built in masonry mortar or low-grade concrete, cement can be completely or partially replaced. Double lime powder is mainly made of quicklime (industrial waste from the calcium carbide plant, sugar mill, and alkali plant), fly ash (industrial furnace, coal gangue, and waste bricks can also be substituted) as the main raw materials, and appropriate catalysts are added at the same time. , stabilizers, coagulants, mixed
