摘要
为了研究高吸水树脂对混凝土强度和工作性能的影响,设计 4 组试验,并分析每组的强度特征和工作性能.结果表明:掺加高吸水树脂的混凝土强度下降了 10%～20%;新拌混凝土的坍落度和扩展度随着时间增长而减小,且减小速度较快,30 min坍落度损失达 19.1%,60 min坍落度和扩展度损失约 47.6%;高吸水树脂的较优掺量为 0.3%;微珠能减小混凝土因掺入高吸水树脂而引起的强度和工作性能的损失,在工程上可以与高吸水树脂复掺使用.文中所得研究成果可为实际工程提供一定的参考依据.
Abstract
In order to investigate the influence of high water-absorbent resin on the strength and workability of con-crete,four sets of experiments are designed to study its strength characteristics and workability.The results show that the addition of high water-absorbent resin reduces the strength of concrete by 10%～20%.The slump and slump flow of fresh concrete decrease rapidly as time goes on,with a slump loss of 20%at 30 minutes and a slump flow loss of approxi-mately 50%at 60 minutes.The optimal addition amount of high water-absorbent resin is 0.3%.Microspheres can reduce the strength and workability losses caused by the addition of highly absorbent resins in concrete.They can be used in conjunction with highly absorbent resins in engineering applications.The research findings of the study can provide a cer-tain reference basis for practical engineering.
