Preparation process of high-performance anti-crack concrete
The invention relates to the technical field of concrete, in particular to a preparation process of high-performance anti-crack concrete, which comprises the following steps: 1, preparation work: preparing Portland cement, aggregate and mineral admixture; the aggregate comprises fine sand and coarse sand; the mineral admixture comprises fly ash, silica fume, slag powder, water and a water reducing agent; step 2, preparing equipment, and step 3, stirring: firstly, sequentially pouring Portland cement, aggregate and water into a stirrer, then enabling the stirrer to continuously stir for 2 minutes, pausing the work of the stirrer, adding fly ash, silicon powder and slag powder into the stirrer, enabling the stirrer to continuously stir for 3 minutes, and stirring for 2 minutes; slowly putting the water reducing agent and the balance of water into the stirrer, and stirring for 5 minutes in the stirrer; and 4, taking out the concrete, and taking out the concrete after the stirring of the stirrer is completed. The strength of the concrete can be obviously improved, and the effect of reducing the cost is achieved.
本发明涉及混凝土技术领域，具体是一种高性能抗裂混凝土的制备工艺，包括以下步骤：第一步：准备工作，准备硅酸盐水泥，骨料和矿物掺合料；骨料包括细砂和粗砂；矿物掺合料包括粉煤灰，硅灰，矿渣粉，水，减水剂；第二步：设备的准备，第三步：搅拌工作，首先向搅拌机的内部依次倒入硅酸盐水泥，骨料以及水，然后使搅拌机继续搅拌2分钟，暂停搅拌机的工作，向搅拌机的内部添加粉煤灰，硅粉和矿渣粉之后，使搅拌机继续搅拌3分钟，将减水剂和余量的水一起缓慢放入搅拌机中，再使搅拌机搅拌5分钟；第四步：取出混凝土，搅拌机搅拌完成之后，将混凝土取出。本发明能使该混凝土的强度有明显的提升，达到了降低成本的效果。
