摘要
再生骨料性能一般低于天然骨料,针对再生骨料吸水率高、强度低等问题,通过化学浆液强化方式对其进行强化,探讨对再生骨料性能、再生混凝土的力学性能和耐久性的影响。研究表明,经化学浆液强化后,再生骨料的压碎指标和吸水率明显降低,再生混凝土的力学性能和耐久性显著提升。
The performance of recycled aggregate is generally lower than that of natural aggregate.Aiming at the problems of high water absorption and low strength of recycled aggregate,it is strengthened by chemical slurry,and the effects of strengthening on the performance of recycled aggregate,mechanical properties and durability of recycled concrete are discussed.The research shows that after strengthening with chemical slurry,the crushing index and water absorption of recycled aggregate are significantly reduced,and the mechanical properties and durability of recycled concrete are significantly improved.
