Concrete gelling accelerator as well as preparation method and application thereof
The invention discloses a concrete gelling accelerator as well as a preparation method and application thereof. The accelerator comprises the following preparation raw materials in parts by weight: 50-80 parts of a composite admixture, 15-35 parts of a composite modifier and 5-15 parts of a reinforcing agent, the composite admixture is prepared from lithium slag powder, metakaolin and a grinding aid; the composite modifier is composed of cement clinker and an exciting agent. A concrete material prepared by using the concrete gelling accelerator disclosed by the invention is good in working performance, the compressive strength is improved by 10%-20%, and the concrete strength is obviously enhanced.
本发明公开了一种混凝土胶凝化促进剂及其制备方法与应用。该促进剂包括以下重量份数的制备原料：复合掺合料50份～80份，复合改性剂15份～35份，增强剂5份～15份；所述复合掺合料由锂渣粉、偏高岭土和助磨剂组成；所述复合改性剂由水泥熟料和激发剂组成。利用本发明的混凝土胶凝化促进剂制得的混凝土材料工作性能良好，抗压强度提高了10％～20％，对混凝土强度具有明显增强作用。
