Pre-strengthening method of construction waste recycled aggregate and inorganic artificial stone plate
The invention discloses a pre-strengthening method of construction waste recycled aggregate and an inorganic artificial stone planes.The pre-strengthening method of the recycled aggregate comprises the following steps that S1, the construction waste recycled aggregate is screened into aggregate with different particle size intervals, impurities are removed, drying treatment is conducted, and the recycled aggregate is obtained; s2, measuring the saturated water absorption rate of the construction waste recycled aggregate; s3, uniformly spraying the pre-strengthening solution on the surface of the recycled aggregate, and sealing the recycled aggregate sprayed with the pre-strengthening solution in a vacuum bag; s4, the vacuum bag filled with the recycled aggregate and the pre-strengthening solution is vacuumized, so that the vacuum degree reaches 97% or above, and the vacuum degree is maintained for 4-12 min; and S5, releasing vacuum to obtain the pre-reinforced recycled aggregate. The recycled aggregate is subjected to pre-strengthening treatment in a vacuum strengthening mode, so that pores and the surface of the recycled aggregate are rapidly filled with active components in a pre-strengthening solution, the cohesiveness of the recycled aggregate and a cementing material is improved, and the strength of the inorganic artificial stone plate is integrally improved.
本发明公开了一种建筑垃圾再生骨料的预强化方法及无机人造石板材，其中再生骨料的预强化方法包括以下步骤：S1：建筑垃圾再生骨料筛分成不同粒径区间的骨料，去除杂质、干燥处理，得到再生骨料；S2：建筑垃圾再生骨料饱和吸水率测定；S3：将预强化溶液均匀喷洒在再生骨料表面，并将喷洒预强化溶液的再生骨料置于真空袋中进行密封；S4：对装有再生骨料及预强化溶液的真空袋进行抽真空处理，使真空达到97％以上并维持4～12min；S5：释放真空，得到预强化再生骨料。本发明通过真空强化方式对再生骨料进行预强化处理，使其孔隙及表面快速填充预强化溶液中的活性组分，提升再生骨料与胶凝材料的粘结性，整体提升无机人造石板材强度。
