利用矿热炉渣、矿渣、精炼渣制备复合水泥

Preparing composite cement with submerged arc furnace slag,blast furnace slagand refining slag

为缓解矿渣等高活性混合材资源的紧张,通过对矿热炉渣、矿渣、精炼渣三种渣按照不同比例复掺进行了试验。试验表明,在加入激发剂后,当矿热炉渣掺量为25%、矿渣为5%、精炼渣为5%时,可配制达到PC42.5水泥;当矿热炉渣掺量为30%、矿渣为15%、精炼渣为5%时,仍可配制合格的PC32.5水泥。

To alleviate high activity admixture（as slag） resource shortage, using different proportion of submerged arc furnace slag, blast furnace slag and refining slag as admixture to prapare composite cement in the experiment. And the results show that with exciting agent, when submerged arc furnace slag, blast furnace slag and refining slag rate is respectively 25%,5%and 5%, PC42.5 cement can be prepared;and when the proportion is 30%,15%and 5%, PC32.5 cement can still be prepared.
