Lightweight high-strength aggregate and lightweight aggregate concrete prepared from same
The invention discloses a lightweight high-strength aggregate, which is prepared from the following raw materials in parts by weight: 20 to 30 parts of cement, 65 to 75 parts of mineral admixture, 1 to 2 parts of thickening agent, 1 to 2 parts of fiber and 100 to 120 parts of water. The cement, the mineral admixture and the thickening agent are used as main raw materials, a thickening agent gelatinization process and a large forming water-solid ratio are combined, good light weight and high strength performance can be considered, and good working performance, mechanical performance and stability performance can be guaranteed when the cement is applied to preparation of lightweight aggregate concrete; the preparation method is simple, convenient to operate and suitable for popularization and application.
本发明公开了一种轻质高强骨料，各原材料及其所占的重量份数包括：水泥20～30份，矿物掺合料65～75份，增稠剂1～2份，纤维1～2份，水100～120份。本发明以水泥和矿物掺合料和增稠剂为主要原料，并结合增稠剂糊化工艺和较大的成型水固比，可兼顾良好的轻质、高强性能，将其应用于制备轻骨料混凝土，可保证良好的工作性能、力学性能和稳定性能；且涉及的制备方法较简单、操作方便，适合推广应用。
