Low-temperature fast-curing concrete and preparation method thereof
The invention belongs to the field of concrete preparation, and particularly relates to low-temperature fast-curing concrete and a preparation method thereof.The preparation method includes the stepsthat water is added into aggregate, even mixing is conducted to enable the aggregate to fully absorb water to obtain pretreated aggregate, then coating treatment is conducted to prepare coated aggregate, the coated aggregate, cement and a water reducing agent are stirred and mixed evenly, water is added, even stirring is conducted, and slurry is obtained; finally, the slurry is injected into a mold for vibration molding, standing and curing are conducted, and concrete can be obtained. The concrete can be quickly cured at a low temperature (-40 to 5 DEG C), and the obtained concrete has high strength.
本发明属于混凝土制备领域，具体涉及一种低温快速固化混凝土及其制备方法，先向骨料中加入水，混匀使得骨料充分吸水得到预处理骨料，接着进行包覆处理制成包覆骨料，再将包覆骨料与水泥、减水剂搅拌混匀，加入水，搅匀得到浆料，最后将浆料注入模具振捣成型，静置固化，即可得到混凝土；该混凝土可在低温(‑40～5℃)条件下快速固化，所得混凝土强度高。
