The invention relates to a concrete solid pumping agent, which comprises a water reducing agent, a retarder, a plastic retaining agent, an air entraining agent, a water retaining agent, an anti-permeability agent, an active material and water, and is prepared by the following steps: uniformly stirring and mixing the water reducing agent, the retarder, the plastic retaining agent, the air entraining agent, the water retaining agent, the anti-permeability agent and the water according to a weight ratio to obtain mixed liquid; smashing an active material, adding the smashed active material into the mixed liquid, and uniformly stirring to obtain a mixture; performing separate stirring so that stirring is more sufficient and uniform, wherein fly ash can delay hydration heating of concrete; andheating and drying the mixture to obtain thesolid pumping agent. The water reducing agent, the retarder, the plastic retaining agent, the air entraining agent, the water retaining agent, the anti-permeability agent and the active material have excellent water reducing and enhancing effects and retarding and plastic retaining properties, the workability of a concrete mixture can be improved, the hydration heating rate is decreased, cracking is avoided, The concrete is denser, and the impermeability and the durability are improved.
本发明涉及一种混凝土固体泵送剂，包括减水剂、缓凝剂、保塑剂、引气剂、保水剂、抗渗剂、活性材料和水，其制作步骤为：将减水剂、缓凝剂、保塑剂、引气剂、保水剂、抗渗剂和水各原料按照重量比搅拌混合均匀，得到混合液体；将活性材料打碎并加入混合液体内搅拌均匀，得到混合物；分开搅拌可以使得搅拌更充分均匀，粉煤灰可以延缓混凝土水化发热；将混合物加热烘干，得到固体泵送剂，本发明中的减水剂、缓凝剂、保塑剂、引气剂、保水剂、抗渗剂、和活性材料，具有卓越的减水增强效果和缓凝保塑性能，可以改善混凝土拌合物提高混凝土拌合物的和易性，并且延缓水化发热速率，避免开裂，使混凝土更密实，提高抗渗性及耐久性。
