Preparation method of high-performance lightweight foam concrete
The invention belongs to the technical field of building materials, and particularly relates to a preparation method of high-performance light-weight foam concrete which comprises the following components in parts by weight: 53-58 parts of water, 90-100 parts of Portland cement, 20-30 parts of fly ash with different particle sizes, 6-8 parts of silica fume, 0.05-0.1 part of a foaming agent, 0.5-1 part of a water reducing agent, 0.08-0.15 part of a thickening agent and 0.1-0.15 part of graphene oxide modified carbon fibers. The proportion of water to the foaming agent is accurately controlled through a calculation formula, a more uniform and compact pore structure is obtained, the compressive strength of the foam concrete is effectively improved, early shrinkage is inhibited, the anti-cracking performance of the concrete is improved, and the industrial value is achieved.
本发明属于建筑材料技术领域，具体涉及一种高性能轻质泡沫混凝土的制备方法，按照重量份数计算，包括如下组分：水53~58份、硅酸盐水泥90~100份、不同粒径的粉煤灰20~30份、硅灰6~8份、泡沫剂0.05~0.1份、减水剂0.5~1份、增稠剂0.08~0.15份、氧化石墨烯改性碳纤维0.1~0.15份，通过计算公式精确控制水和发泡剂的比例，获得更加均匀致密的孔结构，有效提高泡沫混凝土的抗压强度，并抑制早期收缩，提高混凝土的抗开裂性能，具有产业价值。
