Special pumping agent for pumping recycled aggregate concrete
The invention relates to the technical field of pumping agents, and discloses a special pumping agent for pumping recycled aggregate concrete. The pumping agent is composed of a liquid part and a semi-solid part. The pumping agent liquid is prepared from, by weight, a small amount of clear water, 30%-50% of a water reducing agent, 5%-10% of a retarder, 8%-10% of an early strength agent, 0.8%-1.5% of an air entraining agent, 15%-17% of a lubricating agent, 3%-8% of a defoaming agent, 12%-14% of a flow increasing agent, 1%-5% of an adhesive and 10%-13% of an antirust agent. The pumping agent semi-solid is spherical and is composed of a transparent spherical film and a spherical liquid. In spring, summer and autumn, the weather is mild, the pumping agent liquid can be independently used for conveying recycled aggregate concrete, in winter, the weather is cold and the recycled aggregate concrete is easy to freeze, the pumping agent liquid and the pumping agent semi-solid can be used together, the pumping agent semi-solid is composed of a transparent spherical film and a spherical liquid, the spherical liquid is wrapped in the transparent spherical film, the spherical liquid is formed by mixing 80% of an anti-freezing agent and 20% of water. A good anti-freezing effect is achieved, and blockage of concrete in a pipeline in winter is reduced.
本发明涉及泵送剂技术领域，且公开了一种用于泵送再生骨料混凝土的专用泵送剂，所述泵送剂由液体和半固体两部分构成，按照重量备百分比计算，所述泵送剂液体由少量的清水，30%‑50%减水剂、5%‑10%缓凝剂、8%‑10%早强剂、0.8%‑1.5%引气剂，15%‑17%润滑剂、3%‑8%消泡剂、12%‑14%提流剂、1%‑5%粘聚剂、10%‑13%防锈剂配制而成，泵送剂半固体呈圆球状，所述泵送剂半固体由透明球膜、球液构成；在春夏秋季节时，天气温和，可以单独使用泵送剂液体在输送再生骨料混凝土使用，在冬天时，天气冷且容易上冻，可以使用泵送剂液体和泵送剂半固体一起使用，泵送剂半固体由透明球膜、球液构成，透明球膜内包裹球液，球液为80%防冻剂和20%水混合而成，具有良好的防上冻效果，冬天减小混凝土堵塞在管道。
