Light-weight, high-strength and high-durability concrete for fabricated building and preparation method thereof
The invention relates to lightweight high-strength high-durability concrete for a prefabricated building and a preparation method of the lightweight high-strength high-durability concrete, and belongs to the technical field of lightweight concrete. In order to solve the problem that the existing lightweight concrete cannot give consideration to self weight, strength and durability, the invention provides the lightweight high-strength high-durability concrete for the prefabricated building, which comprises the following components: cement, water, fine aggregate, light coarse aggregate, a composite admixture, a water reducing agent, polyacrylonitrile fiber and basalt fiber. The strength grade of the lightweight high-strength high-durability concrete provided by the invention reaches LC50-LC55, the lowest apparent density grade can reach 1700kg/m < 3 >, the self weight of the concrete is reduced while the strength is improved, the durability of the lightweight concrete is further improved, and the requirements of prefabricated buildings on the lightweight concrete are met. The preparation method of the lightweight concrete has an obvious improvement effect on various durability indexes, and the preparation method is simple, convenient and easy to popularize.
本发明涉及一种装配式建筑用轻质高强高耐久性混凝土及其制备方法，属于轻质混凝土技术领域。为解决现有轻质混凝土无法兼顾自重与强度、耐久性的问题，本发明提供了一种装配式建筑用轻质高强高耐久性混凝土，组分包括水泥、水、细骨料、轻粗骨料、复合掺合料、减水剂、聚丙烯腈纤维和玄武岩纤维。本发明提供的轻质高强高耐久性混凝土的强度等级达到LC50～LC55，表观密度等级最低能达到1700kg/m3，在提高强度的同时降低了混凝土的自重，并进一步提高了轻质混凝土的耐久性，满足了装配式建筑对于轻质混凝土的要求。本发明轻质混凝土制备方法对于各项耐久性指标均有明显提升作用，且制备方法简便，易于推广。
