摘 要:锂渣及再生粗骨料对混凝土抗压强度有一定的影响,通过轴心抗压试验获得了立方体与棱柱体抗压强度之间的线性关系。结果表明,适量的再生粗骨料和锂渣可以有效提高混凝土28d抗压强度,当再生粗骨料取代率为30%,锂渣掺量为20%时,28d的立方体和棱柱体抗压强度最大,较同龄期下未掺锂渣的普通混凝土增长了39.1%和48.2%。
Abstract: Lithium slag and recycled coarse aggregates have a certain influence on the compressive strength of concrete, through the axial compressive test, the linear relationship of compressive strength between the cube and prism were obtained. The results show that the right amount of recycled coarse aggregate and lithium slag can effectively improve the 28d compressive strength. When the replacement rate of recycled coarse aggregate is 30% and the lithium slag content is 20%, the 28d compressive strength of cube and prism is the largest, is increased by 39.1% and 48.2% than the compressive strength of the ordinary concrete which is not added by lithium slag in the same age period.
