摘 要:研究了石灰石尾矿粉等质量替代0、10%、20%、30%、40%的水泥对全再生骨料混凝土工作性、力学性能和耐久性能的影响。结果表明:10%掺量的石灰石尾矿粉可以改善全再生骨料混凝土的工作性;随着石灰石尾矿粉掺量的增加,试件的抗压强度呈先增大后减小的趋势,最佳掺量为10%;10%掺量的石灰石尾矿粉可以改善全再生骨料混凝土的抗冻性能和抗碳化性能。
Abstract: The influence of limestone tailing powder content(0, 10%, 20%, 30%, 40%) on the workability, mechanical properties and durability of fully recycled aggregate concrete was studied. The results show that 10% limestone tailing powder can improve the workability of fully recycled aggregate concrete. With the increase of limestone tailing powder content, the compressive strength of the specimen increases first and then decreases, and the optimal content is 10%. 10% limestone tailing powder can improve the frost resistance and carbonation resistance of fully recycled aggregate concrete.
