摘要
研究了混凝土配合比和养护条件对活性粉末混凝土 (RPC)变形率的影响。测定了在不同条件下养护的、具有不同配合比的RPC试样的收缩率。RPC的长期收缩率远小于普通混凝土。优化配合比 ,改善养护条件以及掺加微细钢纤维均能有效减小RPC的收缩率。
The effects of proportion ratio of concrete and curing conditions on the transmogrification rate of reactive powder concrete (RPC) were studied. The shrinkage of RPC specimens with different proportions was measured under the different curing conditions. After long period, the RPC shows even less shrinkage than normal concrete. The shrinkage of RPC can be decreased effectively when favorable concrete proportions and suitable curing conditions were adopted and fine steel fiber was added into the mixture.
