不同混合材对水泥减水剂适应性及胶砂强度的影响

摘要

混合材类型的不同对水泥与减水剂之间的适应性和胶砂强度具有重要的影响。该文对广东某地3种矿物包括河砂、炉渣和铁渣进行粉磨并以一定比例掺入到水泥中，研究其对水泥与减水剂的适应性和胶砂强度的影响规律，为当地矿物资源利用提供参考依据。研究结果表明，掺入铁渣的水泥样品减水剂适应性最好，河砂次之，炉渣最差；掺入炉渣和铁渣的水泥胶砂28d抗压强度比均超过65％，可作为活性混合材使用。%Different kinds of admixtures have a great influence on the compatibility between cement and water reducer and the mor -tar strength .This article studies the effect law of three kinds of admixtures including natural sand , furnace slag and iron slag which were milled and mixed into the cement in a certain ratio on the water reducer compatibility of cement and mortar strength , then pro-vides reference for local manufacturers to optimize the use of resources and control the cost of the cement .The result shows that the cement mixed with iron slag is the best on water reducer compatibility , natural sand is a little worse and furnace slag is the worst . Ratio of cement mortar compression strength with 28 days all exceed 65%for furnace slag and iron slag which are all available for active admixture .
