Processing method of pre-wetted porous basalt aggregate concrete
The invention relates to a processing method of pre-wetted porous basalt aggregate concrete. The processing method comprises the following steps: step 1, crushing and screening porous basalt to obtain a fine porous basalt material with the particle size of 4.75-10mm and a coarse porous basalt material with the particle size of more than 10mm and less than or equal to 19mm; 2, soaking the porous basalt coarse material in water, humidifying for 40-55 hours, and then taking out the porous basalt coarse material to obtain the pre-wetted porous basalt coarse material; 3, weighing the raw materials according to the raw material formula of the concrete, pouring into a stirrer, and uniformly stirring to form a mixture; the later compressive strength of the concrete prepared from the pre-wetted porous basalt aggregate is higher than the strength of the concrete prepared from the non-pre-wetted porous basalt aggregate, and the chloride ion penetration resistance of the concrete prepared from the pre-wetted porous basalt aggregate is higher.
一种预湿多孔玄武岩骨料混凝土的加工方法，包括下列步骤：步骤1：对多孔玄武岩进行破碎，筛分得到粒径为4.75‑10mm的多孔玄武岩细料，粒径大于10mm且小于或等于19mm的多孔玄武岩粗料；步骤2：将多孔玄武岩粗料用水浸泡加湿40‑55h，然后取出多孔玄武岩粗料，即得预湿后的多孔玄武岩粗料；步骤3：按混凝土的原料配方称量原料，倒入搅拌机搅拌均匀形成拌合物。预湿后的多孔玄武岩骨料制混凝土，其后期抗压强度比没有预湿的多孔玄武岩骨料所制成的混凝土的强度高，预湿多孔玄武岩骨料配制的混凝土的抗氯离子渗透能力也更强。
