Method for preparing concrete by using porous basalt as aggregate
The invention discloses a method for preparing concrete by using porous basalt as aggregate. The method comprises the following steps: step 1, crushing and screening the porous basalt to obtain porous basalt machine-made sand with the particle size of less than 4.75 mm and porous basalt coarse aggregate with the particle size of 4.75-19 mm; 2, weighing the porous basalt machine-made sand and the porous basalt coarse aggregate according to the raw material formula of the concrete, pouring into a stirrer, and uniformly stirring to form a mixture; the raw material formula of the concrete comprises the following raw materials in parts by weight: 300 to 500 parts by weight of cement, 50 to 90 parts by weight of fly ash, 450 to 700 parts by weight of porous basalt machine-made sand, 1150 to 1200 parts by weight of porous basalt coarse aggregate, 7 to 12 parts by weight of a water reducing agent and 170 to 190 parts by weight of water. The porous basalt aggregate disclosed by the invention is used for concrete, has many pores and is very hard, so that when the porous basalt aggregate is mixed in the concrete, the weight of the concrete can be reduced, but the concrete is still very firm, and the porous basalt aggregate has the characteristics of sound insulation, heat insulation and the like, and is a good aggregate of lightweight concrete for high-rise buildings.
一种利用多孔玄武岩作骨料制作混凝土的方法，包括下列步骤：步骤1：对多孔玄武岩进行破碎，筛分得到粒径小于4.75mm的多孔玄武岩机制砂和粒径4.75~19mm的多孔玄武岩粗骨料；步骤2：按混凝土的原料配方称量多孔玄武岩机制砂、多孔玄武岩粗骨料，倒入搅拌机搅拌均匀形成拌合物；所述混凝土的原料配方包括下列重量份的原料：300‑500重量份的水泥、50‑90重量份的粉煤灰、450‑700重量份的多孔玄武岩机制砂、1150‑1200重量份的多孔玄武岩粗骨料、7‑12重量份的减水剂、170‑190重量份的水。本发明的多孔玄武岩骨料用于混凝土，因为它气孔多，又相当坚硬，因此，将它搀在混凝土里，可以使混凝土重量减轻，但仍很坚固，同时有隔音、隔热等特点，是高层建筑轻质混凝土的良好骨料。
