Self-flowing heat-resistant concrete utilizing reclaimed materials
The invention relates to the technical field of concrete preparation, in particular to self-flow heat-resistant concrete utilizing reclaimed materials. The concrete comprises the following components in parts by mass: 75-77 parts of heating furnace wall reclaimed materials, 10-12 parts of aluminum oxide micro powder, 6-8 parts of micro silicon powder, and 5-7 parts of calcium aluminate cement, and further comprises 0.15-0.25 part of polycarboxylate superplasticizer. The self-flow heat-resistant concrete is prepared by crushing the heating furnace furnace wall recycled material which is burnt at a high temperature for a long time, and organically proportioning the crushed material with other components according to a corresponding proportion. The advantages of good heat resistance, compact structure, low water absorption, high strength and small thermal expansion of the furnace wall recycled material of the heating furnace are fully utilized. The self-flowing property, heat resistance, heat conductivity and stability of the self-flowing heat-resistant concrete in the prior art are improved, meanwhile, high-value recycling of the heating furnace wall is achieved, the environment is improved, and the comprehensive utilization value of resources is increased.
本发明涉及混凝土制备技术领域，具体涉及一种利用回收料的自流耐热混凝土，其组分按质量份计包含：加热炉炉墙回收料75～77份，氧化铝微粉10～12份，微硅粉6～8份，铝酸钙水泥5～7份，在此基础上外加聚羧酸减水剂0.15～0.25份。本发明将经高温长时间灼烧过的加热炉炉墙回收料粉碎后，与其它组分按相应比例有机配比制备成自流耐热混凝土，充分利用了加热炉炉墙回收料耐热性好，结构致密，吸水率低且强度高，热膨胀性小的优点，改善了现有技术中自流耐热混凝土的自流性、耐热性、导热性和稳定性，同时，实现了加热炉炉墙的高价值回收利用，有利于改善环境并提高资源的综合利用价值。
