Preparation method of composite lightweight concrete
The invention relates to the technical field of concrete, and discloses a preparation method of composite lightweight concrete. The ceramsite is used for replacing stones in traditional concrete, so that the concrete is lighter, the heat preservation and sound insulation effects are better, and the heat conductivity coefficient can be effectively improved; by using polyvinyl alcohol, the strengthof the concrete can be improved, the phenomenon that the concrete is broken after being coagulated is effectively prevented, the polypropylene fibers are cheaper than existing polyimide fibers, the cost is saved, and meanwhile the purposes of improving the mechanical strength and the sound insulation, heat preservation and fire prevention performance are achieved; through using thehydroxypropyl methylcellulose, the tensile strength and the shearing strength are improved while the bonding strength is improved, the construction effect is greatly improved, and the working efficiency is improved;the ground calcium carbonate plays a role in lubricating the composite lightweight concrete, so that the concrete is better formed in a flowing manner in a viscous state, and the purpose of shorteningthe construction time is achieved.
本发明涉及混凝土技术领域，公开了一种复合轻质混凝土配制方法。本发明通过使用陶粒代替传统混凝土中的石子，在使混凝土更轻的同时能够使保温和隔音效果更好，也能够有效改善导热系数；通过使用聚乙烯醇能够增加混凝土的强度，有效防止混凝土凝结后出现断裂现象，并且聚丙纤维比于现有的聚酰亚胺纤维更便宜，节约成本的同时达到提高机械强度和隔音、保温、防火性能的目的，通过使用羟丙基甲基纤维素，增加粘结强度的同时提高抗拉伸度和剪切强度，极大改善施工效果，提高工作效率；重质碳酸钙在复合轻质混凝土充当润滑的作用，使混凝土在粘稠的状态下更好流动成型，从而达到缩短施工时间的目的。
