Anti-cracking and anti-freezing concrete and preparation method thereof
According to the anti-cracking and anti-freezing concrete and the preparation method thereof. A net-shaped supporting system is formed in concrete through fly ash bead strings and nano silicon dioxide bead nets to delay and prevent early-stage plastic cracks generated by plastic shrinkage of the concrete, a traction effect can be achieved in the concrete, and the anti-cracking performance of the concrete is remarkably improved; by introducing the polydimethylsiloxane, the pore size in the concrete is greatly reduced, the mechanical strength of the concrete can be improved while the weight of the concrete is reduced, and the acrylic resin can be gradually generated after the acrylic emulsion reacts to fill gaps in the concrete, so that the crack resistance of the concrete is improved while the crack resistance of the concrete is improved, and the concrete is endowed with relatively high mechanical resistance; due to the addition of sodium dodecyl benzene sulfonate, the concrete has certain anti-freezing capability, does not generate steel bar corrosion, can be used at the temperature of-10 DEG C, and has very good durability; and the anti-cracking and anti-freezing concrete has the advantages of convenient preparation, crack resistance, frost resistance and strong practicability.
一种抗开裂抗冻混凝土及其制备方法，通过粉煤灰珠串、纳米二氧化硅珠网在混凝土内形成网状的支撑体系来延缓和阻止混凝土由于塑性收缩产生的早期塑性裂缝，并能够在混凝土内部起到牵拉作用，显著提高混凝土的抗裂性；通过引入聚二甲基硅氧烷，大大缩小混凝土内的气孔尺寸，在实现减轻混凝土重量的同时，能够提高混凝土的机械强度，而丙烯酸乳液经反应后可逐渐生成丙烯酸树脂，填充混凝土内部的间隙，在提高混凝土抗裂性能的同时，赋予混凝土较强的耐机械力性能；十二烷基苯磺酸钠的添加，使混凝土具备一定抗冻能力，且不会产生钢筋锈蚀，可在零下10度下使用，具有很好的耐久性；本发明具有制取方便，抗裂抗冻及实用性强的优点。
