Large-flow-state super high-rise pumping ceramsite concrete
The invention relates to the field of green building materials, and discloses large-flow-state super high-rise pumping ceramsite concrete which comprises 487 parts of shale ceramsite, 731 parts of river sand, 555 parts of a cementing material, 180 parts of water and 14 parts of a polycarboxylic acid type water reducing agent, the bulk density of the shale ceramsite is 758.1 kg/m < 3 >, the apparent density is 1430.1 kg/m < 3 >, and the maximum particle size is 16 mm. When the shale ceramsite is used for preparing the concrete, the use amount of the natural coarse aggregate can be effectively reduced, and the environmental problems of water and soil loss, dust pollution, vegetation damage and the like caused by over-exploitation of the natural coarse aggregate are relieved.
本发明涉及绿色建筑材料领域，且公开了一种大流态超高层泵送陶粒混凝土，包括页岩陶粒487份、河砂731份、胶凝材料555份、水180份以及聚羧酸型减水剂14份，页岩陶粒的堆积密度为758.1kg/m3，表观密度为1430.1kg/m3，最大粒径为16mm，该大流态超高层泵送陶粒混凝土，使用页岩陶粒制备混凝土，可以有效降低天然粗骨料的使用量，缓解过度开采天然粗骨料带来的水土流失、粉尘污染、以及植被破环等环境问题。
