Recycled fine aggregate high-strength self-compacting concrete and preparation method thereof
The invention discloses recycled fine aggregate high-strength self-compacting concrete and a preparation method thereof.The recycled fine aggregate high-strength self-compacting concrete is prepared from, by weight, 18%-30% of artificial sand fine aggregate, 15%-22% of perlite aggregate, 10%-15% of cementing material, 10%-15% of cement, 10%-15% of superfine mineral powder, 10%-20% of water and 10%-20% of reinforced mixed material, based on the total weight of the raw materials, the proportion of the cement is 12-19%, the proportion of the superfine mineral powder is 10-16%, the proportion of the water is 10-20%, and the proportion of the reinforced mixed material is 10-20%. According to the recycled fine aggregate high-strength self-compacting concrete and the preparation method thereof, the recycled fine aggregate and the reinforced mixed material are arranged, so that the forming effect of the concrete can be improved, the microstructure of the concrete can be improved, the mechanical property and durability of the concrete can be improved, the working performance can also be improved, the strength is relatively high, and the durability is excellent; the recycled fine aggregate concrete is high in carbonization resistance, excellent in frost resistance and chloride ion permeability resistance and more practical.
本发明公开了一种再生细骨料高强自密实混凝土及其制备方法，包括人工砂细骨料、珍珠岩骨料、胶结料、水泥、超细矿粉、水与增强混合材料，所述人工砂细骨料的份额为18‑30％，所述珍珠岩骨料的份额为15‑22％，所述胶结料的份额为10‑15％，所述水泥的份额为12‑19％，所述超细矿粉的份额为10‑16％，所述水的份额为10‑20％，所述增强混合材料的份额为10‑20％。本发明所述的一种再生细骨料高强自密实混凝土及其制备方法，设有再生细骨料与增强混合材料，能够增加混凝土的成型效果，改善混凝土的微观结构，提高混凝土的力学性能和耐久性能，还可以增加工作性能、强度较高、耐久性优异，再生细骨料混凝土抗碳化性能较强，抗冻性能与抗氯离子渗透性更为优异，更为实用。
