摘要
通过对108个再生混凝土试块的轴压试验,研究泥土杂质对再生混凝土强度性能的影响。研究结果表明:含有泥土的再生混凝土7d抗压强度能够达到28d抗压强度的56%~63%;水灰比从0.36增大到0.45,再生混凝土的强度下降幅度较大,水灰比从0.45增大到0.53,强度基本无变化;含泥量小于3%基本不影响再生混凝土的抗压强度。
Based on axially compressive test of 108 recycled concrete test block,this paper explores the influence of the soil of impurities on strength properties of recycled eoncrete.The test results showed that:The compressive strength of recycled concrete containing soil impurities can reach 56% to 63% in 7d; Water-cement ratio increased from 0.36 to 0.45,The strength of" the recycled concrete containing soil impurities downward trend, and have a large decline,water-cement ratio increased from 0.45 to 0.53, the strength almost unehanged ;When the mud content is less than 3%,the compressive strength of recycled concrete does not substantially affect.
