诺兰达炉渣综合利用研究(上)

Study on Comprehensive Utilization of Nolanda Furnace Slags (Part Ⅰ)

诺砂中含有 70 %～ 80 %的铁橄榄石矿物成分 ,是自然界中罕见的矿产资源。诺砂中的非晶质玻璃相、初生态铁橄榄石及水解反应中生成的Fe(OH) 3 与Fe(OH) 2 凝胶体 ,它们在水泥混凝土制品中有“活化”、“密填”及“胶凝”3种增强作用。通过大量试验数据及生产实践证实上述结论的可靠性。若能将诺砂有效利用 ,定能获得丰厚的经济效益。

Nolanda sands contain 70%～ 80% fayalite mineral component and is a rare mineral resource in natural world. The noncrystal glass phase and newformed fayalite in Nolana sands and Fe(OH) 3 and Fe(OH) 2 gelignite that are generated in hydrolysis reaction can perform three enhancing functions in concrete product, namely “activation”, “dense filling” and “gelation”. The reliability of the above conclusions are proved by a large amount of test and production data. Rich economic benefit will be surely obtained if Nolanda sands can be effectively utilized.
