Anti-crack environment-friendly concrete
The invention provides anti-crack environment-friendly concrete and a preparation method thereof. Recycled concrete is used in the concrete and is modified and regenerated, tiny cracks generated in the concrete due to crushing or during service are sealed, and meanwhile, a protective layer is formed on the surface to modify a microstructure of the surface, so that the water absorption rate is reduced; and mineral powder is doped, so that the setting time is prolonged, and the impermeability and corrosion resistance of the concrete are improved. A crack reducing agent absorbs heat generated by water and reaction in the concrete and is softened into viscous fluid to be dispersed in the concrete, gaps in the concrete are filled, and cracking and collapse of the concrete are effectively reduced. A curing reinforcing agent contains mortar and is coated and protected by an outer coating layer, the property of a coating film is similar to that of the crack reducing agent, when the temperature rises, an outer mold is softened, the property of an adhesive of the internal mortar is changed, a gap is filled, and the concrete has a certain self-crack reducing and curing function.
本发明提供了一种抗裂环保混凝土及其制备方法。其中，混凝土中使用再生混凝土，并对其进行改性再生，封闭其中上由于破碎或在服役时产生的微小裂缝，同时在表面形成保护层改性表面的微结构，减少吸水率；掺入矿粉，延长凝结时间，提高混凝土抗渗和抗腐蚀能力。减裂剂吸收砼内部由于水和反应产生的热量，软化变成粘性流体分散在混凝土中，填补其中的空隙，有效减少混凝土的开裂和坍塌。固化增强剂内部含有砂浆，由外层包被层包覆保护，包被膜的性质近似于减裂剂，当温度升高，外模软化，内部砂浆的粘合剂性质改变，填补空缺，使混凝土有一定的自我减裂治愈功能。
