Veneer ultra-high performance concrete spraying material and processing equipment thereof
The invention discloses a facing ultra-high performance concrete spraying material and processing equipment thereof, and belongs to the technical field of concrete processing. Comprising the following components in percentage by mass: 23.6%-38.2% of water, 22.8%-45.2% of white Portland cement, 22.5%-33.4% of fine aggregate, 7.4%-15.8% of quick lime, 5%-14.6% of a metal admixture (lead and zinc tailings), 0.5%-1.2% of talcum powder, 0.08%-0.6% of a coagulant, 0.02%-0.3% of a water reducing agent, 0.04%-0.3% of a defoaming agent and 0%-0.4% of an anti-freezing agent. The quick lime raw material is added into the concrete spraying material to increase the solidification temperature of the concrete spraying material, the spraying material can be rapidly solidified after being sprayed out on the premise that the fluidity of the spraying material is not affected, the talcum powder is added into the mixed concrete, the white cleanliness of the surface of the concrete spraying material can be remarkably improved, and the concrete spraying material has the beneficial effects of being environmentally friendly and free of pollution. And the talcum powder is used as a reinforcing and modifying filler, so that the deformation amount in the concrete setting process can be reduced, and the uniformity of concrete ingredients is remarkably improved.
本发明公开了饰面超高性能混凝土喷料及其加工设备，属于混凝土加工技术领域，包括按百分比质量下的如下组分：水23.6％‑38.2％、白色硅酸盐水泥22.8％‑45.2％、细骨料22.5％‑33.4％、生石灰7.4％‑15.8％、金属掺合料(铅锌尾矿石)5％‑14.6％、滑石粉0.5％‑1.2％、促凝剂0.08％‑0.6％、减水剂0.02％‑0.3％、消泡剂0.04％‑0.3％和防冻剂0％‑0.4％。本发明通过在混凝土喷料中加入生石灰原料来提高混凝土喷料凝固时的温度，在不影响喷料流动性的前提下，使得喷料在喷出后能实现快速凝结，在混合后的混凝土中添加滑石粉，能显著的提高混凝土喷料表面的白净度，并且滑石粉作为强化改质填充剂，能降低在混凝土凝固过程中的变形量，显著的提高混凝土配料的均匀性。
