摘 ? 要:通過單摻、復摻無機材料和有機材料對再生大骨料進行改性處理,研究了改性再生大骨料混凝土(MAC)與天然骨料混凝土(NAC)、再生骨料混凝土(RAC)的耐久性能差異。結果表明:相同齡期下,NAC的抗滲性能、抗氯離子滲透性能及抗碳化性能均最好,MAC次之,RAC最差;隨著齡期的延長,RAC碳化深度的增幅最大,MAC次之,NAC最小。
Abstract: The recycled big aggregate was modified through the single admixture and compound admixture of inorganic materials and organic materials, the difference in durability between modified recycled big aggregate concrete(MAC), natural aggregate concrete(NAC) and recycled aggregate concrete(RAC) was studied. The results show that at the same age, NAC has the best anti-permeability, anti-chloride ion permeability and anti-carbonization properties, followed by MAC, and RAC is the worst. With the extension of age, the increase in RAC carbonization depth is the largest, followed by MAC, and NAC is the smallest.
