Micro-expansive, self-compacting and self-curing concrete and preparation method thereof
The invention belongs to the technical field of concrete structures, and particularly discloses concrete with the properties of micro-expansion, self-compaction, self-curing and the like, the concrete comprises common concrete, and the common concrete is doped with an expanding agent, SAP, silica fume and a water reducing agent; the common concrete comprises cement, natural sand, gravel and water, and the mass ratio of the cement to the natural sand to the gravel to the water is 1: 1.6: 2.3: 0.3; wherein the expanding agent equivalently replaces 6%-10% of the cement by adopting an internal doping method, the SAP accounts for 0.1%-0.5% of the cementing material by adopting an external doping method, the silica fume equivalently replaces 4%-8% of the cement by adopting an internal doping method, and the water reducing agent accounts for 1%-2% of the cementing material by adopting an external doping method; the expansion agent, the water reducing agent, the super absorbent resin and the silica fume are doped into the concrete components, so that the shrinkage of the concrete caused by hydration, temperature, carbonization, drying and the like is compensated, and the flowability of the concrete is improved.
本发明属于混凝土结构技术领域，具体公开了一种具有微膨胀、自密实和自养护等性质的混凝土，包括普通混泥土，所述普通混泥土中掺入膨胀剂、SAP、硅灰和减水剂；所述普通混泥土包括水泥、天然砂、碎石和水，所述水泥、天然砂、碎石和水的质量比为1∶1.6∶2.3∶0.3；其中膨胀剂采用内掺法等量代替水泥6%~10%，SAP采用外掺法掺量为胶凝材料的0.1%~0.5%，硅灰采用内掺法等量代替水泥4%~8%，减水剂采用外掺法掺量为胶凝材料的1~2%；通过在混凝土组分中掺加膨胀剂、减水剂、高吸水树脂和硅灰，补偿了混凝土因水化、温度、碳化、干燥等作用导致的收缩，提高了混凝土的流动性。
