摘要:
基于最紧密堆积原则的配合比设计及大量试配，得到活性粉末混凝土（RPC）的理论配合比，以胶凝材料、粗骨料、钢纤维、养护制度、龄期为主要变化参数，设计28组边长为100 mm的立方体抗压试件，测得其立方体抗压强度及二次抗压强度，在此基础上分析不同因素对抗压强度的影响规律结果表明：各试件的抗压强度均达到130 MPa以上，且二次抗压强度均可达到110 MPa；RPC的抗压强度随水胶比的增大而减小，随钢纤维掺量的增大而增大；RPC在热水养护条件下的强度较高，龄期的影响较小，RPC在常温养护下的强度随龄期的增长而显著增大.
Abstract:
The theoretical mix ratio of reactive powder concrete (RPC) was obtained by the most closely packed principle and a large number of trial. Based on the parameters of cementitious material, coarse aggregate, steel fiber, curing system and age, 28 groups of cubic specimens with 100 mm side length were designed. The compressive strength and secondary compressive strength of the specimens were measured, and the influence of different factors on the compressive strength was analyzed. The results show that the compressive strength of all specimens are more than 130 MPa, and the secondary compressive strength can reach 110 MPa. The compressive strength of RPC is decreased with the increase of water-cement ratio and increased with the increase of steel fiber content. The compressive strength of RPC is high under the conditions of hot water conservation, and the effect of age is little. The strength of RPC under normal temperature is increased obviously with the growth of the age.
