摘要
针对再生骨料压碎指标大、孔隙率高、吸水率高等缺点,选用三种不同配比的化学浆液改善其工作性能,测定抗压强度、弹性模量等力学性能,探讨改性方法对再生骨料混凝土力学性能的影响进行了研究。
Aiming at the shortcomings such as high crushing index,high porosity and high water absorption of recycled aggregate,used three chemical agents with different proportions to improve their working performance.The mechanical properties of compressive strength and elastic modulus were measured.Discussed the effects of modification methods on the mechanical properties of recycled aggregate concrete.
