摘要
针对现有提高水泥材料低脆性方法不利于大量推广使用的不足,介绍了采用掺加马尾松质木材锯末用于改善水泥材料的低脆性,室内试验结果表明,马尾松锯末的加入,提高了水泥胶砂的折压强度比,降低了材料的脆性,且价格低廉、施工方便。
Nowadays there are lots of handicaps to develop the me as ures of reducing the cement material brittleness. Through experiments and resear ch, the Pinus massoniana sawdust admixture can increase the bend-press ratio of cement material, besides, the sawdust is very cheap and convenient to use in eng ineering structures.
