高强混凝土速凝剂

High-strength concrete accelerator

Abstract

高强混凝土速凝剂,它由如下重量百分比的原料组成:铝氧熟料40-60%、碧石渣或沸腾炉渣20-30%、钒渣12-25%、高效减水剂4-6%、普通减水剂1-2%,其中铝氧熟料由如下重量百分比的原料组成:钛渣28-33%、纯碱25-28%、石灰石28-32%、煤11-15%。该高强混凝土速凝剂所用原料中有50%是工业废渣,其生产成本低,技术性能先进,凝结时间短、早期强度及后期强度均高,增加喷射混凝土的粘结力,减少回弹率,减少粉尘,节约水泥,提高施工效率,因此本发明具有突出的经济效益、环保效益和社会效益。
The invention discloses a high-strength concrete accelerator, which comprises the following parts: 40-60% alundum clinker, 20-30% green stone slag or boiling stove slag, 12-25% vanadium slag, 4-6% high-effective dehydragent and 1-2% common dehydragent, wherein the alundum clinker is composed of 28--33% titanium slag, 25-28% pure alkaline, 28-32% limestone and 11-15% coal.
