Alkali-activated cementing material retarder
The invention relates to an alkali-activated cementing material retarder. The alkali-activated cementing material retarder is composed of cheap sulfate and sulphoaluminate, and a small amount of auxiliaries can be added in the grinding process or in the concrete (mortar) mixing process. According to the invention, cheap sulfate and sulphoaluminate are used as retarders in a slag fly ash system to replace part of slag fly ash, so that the initial and final setting time of the alkali-activated cementing material is effectively prolonged, and the construction problem and quality defect caused by too short setting time of the alkali-activated cementing material are avoided.
本发明涉及一种碱激发胶凝材料缓凝剂。该碱激发胶凝材料缓凝剂，采用廉价硫酸盐与硫铝酸盐组成，可以加入少量助剂，在粉磨过程加入也可在混凝土（砂浆）拌和时加入。本发明用廉价的硫酸盐和硫铝酸盐作为缓凝剂用于矿渣粉煤灰体系中，取代部分矿渣粉煤灰，有效延长了碱激发胶凝材料的初、终凝结时间，避免了碱激发胶凝材料凝结时间过短导致的施工问题以及质量缺陷。
