Full-hole slag concrete and preparation method thereof
The invention discloses full-hole slag concrete and a preparation method thereof, and belongs to the technical field of solid waste resource utilization. The hole slag is crushed into the machine-made sandstone aggregate, so that the cost for transporting the sandstone aggregate for a long distance is saved; the mudstone-containing powder and the soil curing agent are firstly mixed and then stood, so that the internal structure of the soil is compact, the hydrophobicity is also increased, and the water absorption rate is reduced; the cavernous slag quick lime obtained by calcining the cavernous slag fine aggregate with high calcium carbonate content has a certain gelling property and can be used as a chemical activity activator of the volcanic ash cavernous slag stone powder, and the cavernous slag quick lime and the volcanic ash cavernous slag stone powder are jointly used as a gelling material to replace Portland cement as a raw material of concrete. The anti-crack reinforcing ribs formed by cutting plant stalks such as branches and trunks mingled in the hole slag can cross the two ends of the crack in the whole hole slag concrete, the bridging effect is achieved, the crack of the whole hole slag concrete is prevented from further developing, and then the effects of resisting the crack and replacing reinforcing steel bars are achieved.
本发明公开了一种全洞渣混凝土及其制备方法，属于固废资源化利用技术领域。本发明采用洞渣破碎成机制砂石骨料，省去了长距离运输砂石骨料的费用；含泥石粉与泥土固化剂先混合再静置，使泥土内部结构密实，还增加了憎水性，降低了吸水率；高碳酸钙含量的洞渣细骨料进行煅烧得到的洞渣质生石灰本身具有一定的胶凝性能，而且能作为火山灰质洞渣石粉的化学活性激发剂，洞渣质生石灰和火山灰质洞渣石粉共同作为胶凝材料代替硅酸盐水泥作为混凝土的原料。采用洞渣中夹杂的树枝树干等植物茎秆切割形成的抗裂加强筋，能在全洞渣混凝土中跨越裂缝的两端，起到“桥接”的作用，防止全洞渣混凝土裂缝进一步发展，进而起到抗裂和替代钢筋的作用。
