Lightweight composite concrete and preparation process thereof
The invention discloses lightweight composite concrete and a preparation process thereof. The lightweight composite concrete is prepared from the following raw materials in percentage by weight: 50%-65% of cement, 4%-8% of silica fume, 4%-10% of fly ash, 4%-8% of slag, 8%-10% of an expanding agent, 4%-10% of coarse aggregate, 2%-8% of fine aggregate and 0.5%-1% of a high-efficiency water reducing agent, and the water consumption of one part of the raw materials is 150-170L. According to the light-weight composite concrete and the preparation process thereof, the water reducing agent is selected, during preparation, large fluidity can be achieved, fluidity loss is almost avoided, and when the concrete doped with silica fume is used, the bonding degree, compressive strength and breaking strength are obviously improved, and the light-weight composite concrete is suitable for being used in a large scale. Meanwhile, during preparation, the cost is low, the efficiency is high, the requirement that a reinforcing project needs to be demoulded as soon as possible to be put into use can be met, the concrete is more beneficial to being used in a structure reinforcing project, and the ideal reinforcing effect can be achieved.
本发明公开了一种轻量化复合混凝土及其制备工艺，所述原材料按份额包括50%‑65%的水泥、4%‑8%的硅灰、4%‑10%的粉煤灰、4%‑8%的矿渣、8%‑10%的膨胀剂、4%‑10%的粗集料、2%‑8%的细集料、0.5%‑1%的高效减水剂，一份所述原材料用水量为150L‑170L。本发明所述的一种轻量化复合混凝土及其制备工艺，发明通过选用的减水剂，在进行制备时，能实现较大的流动度，且流动性损失几乎没有，且此掺有硅灰的混凝土在进行使用时，粘结程度、抗压强度、抗折强度上均有明显提升，同时在进行制备时，成本较低，效率较高，能满足加固工程尽快拆模投入使用的要求，此混凝土更加有利于御用在结构加固工程，能达到理想的加固效果。
