Anti-crack durable hole slag aggregate concrete and preparation method thereof
The invention provides anti-crack durable hole slag aggregate concrete.The anti-crack durable hole slag aggregate concrete is prepared from 750-810 parts of sulphoaluminate cement, 120-180 parts of silica fume, 18-28 parts of expanding agent, 50-70 parts of polypropylene fiber, 2100-2300 parts of hole slag coarse aggregate, 1500-1600 parts of hole slag fine aggregate, 22-28 parts of polycarboxylate superplasticizer and 300-330 parts of water.The preparation method includes the steps that the polycarboxylate superplasticizer is added into water and stirred to obtain a uniform water solvent, and the water solvent is added into the hole slag coarse aggregate and stirred to obtain the anti-crack durable hole slag aggregate concrete; and slowly adding the mixture into the uniform mixture, then adjusting the working parameters of the rotary mixing stirrer for mixing to obtain uniformly mixed slurry, and finally forming and curing according to the national standard to obtain the anti-crack durable hole slag aggregate concrete. The green ecological concrete is prepared from tunnel hole slag as coarse and fine aggregate, development of natural aggregate is reduced, the engineering cost is reduced, and meanwhile, the hole slag aggregate concrete with good mechanical property and durability is prepared by improving the internal structure.
本发明提供一种抗裂耐久洞渣骨料混凝土，包括以下比例的原料：硫铝酸盐水泥750～810份、硅灰120～180份、膨胀剂18～28份、聚丙烯纤维50～70份、洞渣粗骨料2100～2300份、洞渣细骨料1500～1600份、聚羧酸减水剂22～28份、水300～330份.本发明通过将聚羧酸减水剂加入水中，搅拌得到均匀的水溶剂，缓慢加入到均匀混合料中，然后调节旋转式混合搅拌机的工作参数进行混合，得到均匀混合浆体，最后按国家标准成型养护，即可得到所述抗裂耐久洞渣骨料混凝土。本发明原料采用隧道洞渣作为粗细骨料，制备绿色生态混凝土，减少了天然骨料的开发，降低了工程成本，同时通过改善内部结构，制备具有良好的力学性能以及耐久性能的洞渣骨料混凝土。
