Clay-based recycled aggregate concrete and manufacturing method thereof
The invention discloses clay-based recycled aggregate concrete and a manufacturing method thereof. The clay-based recycled aggregate concrete is prepared from the following raw materials in parts by weight: 14.9 to 28.9 parts of 42.5-grade ordinary Portland cement, 21.4 to 33.7 parts of washed sand, 0 to 46.7 parts of clay-based recycled aggregate with the particle size of 20mm, 0 to 16.7 parts of pebbles with the particle size of 5mm, 0 to 27.7 parts of pebbles with the particle size of 10 to 20mm, 0 to 0.1 part of polycarboxylate superplasticizer and 6.2 to 10.3 parts of water. The clay-based recycled aggregate is used for replacing pebbles to prepare clay-based recycled aggregate concrete, and indoor curing and soaking curing are carried out. The clay-based recycled aggregate raw material used in the invention is cheap and easily available, can effectively replace stones, reduces the cost of the concrete material, improves the working performance of the concrete, and also effectively solves the technical problem of high value-added resource utilization of the engineering spoil.
本发明公开一种黏土基再生骨料混凝土及其制造方法，所述黏土基再生骨料混凝土包括下列重量份原料：42.5级普通硅酸盐水泥14.9～28.9份、水洗砂21.4～33.7份、粒径为20mm的黏土基再生骨料0～46.7份、粒径为5mm的石子0～16.7份、粒径为10‑20mm的石子0～27.7份、聚羧酸减水剂0～0.1份、水6.2～10.3份；将黏土基再生骨料替代石子配制黏土基再生骨料混凝土，并进行室内养护和浸水养护。由于本发明所用黏土基再生骨料原材料价廉易得，可有效替代石子，降低了混凝土材料成本，并改善了混凝土工作性能，还有效解决了工程弃土高附加值资源化利用技术难题。
