Environment-friendly pumping concrete with high workability
The invention relates to environment-friendly pumping concrete with high workability, belonging to the technical field of building materials. The environment-friendly pumping concrete is prepared fromthe following components in parts by weight: 250 to 300 parts of cement, 120 to 140 parts of fly ash, 900 to 1000 parts of broken stone, 380 to 400 parts of machine-made sand, 540 to 580 parts of stone powder, 160 to 200 parts of water, 60 to 80 parts of mineral powder and 14 to 18 parts of a pumping agent, wherein the pumping agent comprises, in parts by weight, 4-5 parts of a polyester type polycarboxylate superplasticizer, 6-9 parts of a polyether type polycarboxylate superplasticizer, 2-4 parts of an air entraining agent and 1-2 parts of a sodium gluconate retarder; and the weight percentage of wastewater in the water is 0-50%, and the weight percentage of tap water in the water is 50-100%. The concrete has the effect of high workability.
本发明涉及一种高和易性的环保泵送混凝土，属于建筑材料的技术领域，其按重量份计包括以下组分：水泥250‑300份，粉煤灰120‑140份，碎石900‑1000份，机制砂380‑400份，石粉540‑580份，水160‑200份，矿粉60‑80份，泵送剂14‑18份；所述泵送剂按重量份计包括：聚酯型聚羧酸减水剂4‑5份，聚醚型聚羧酸减水剂6‑9份，引气剂2‑4份，葡萄糖酸钠缓凝剂1‑2份；水中废水的重量百分数为0‑50%，其余为自来水。本发明具有和易性高的效果。
