Preparation method of high-temperature-resistant concrete material capable of effectively resisting fire damage as well as product and application of high-temperature-resistant concrete material
The invention discloses a preparation method and product application of a high-temperature-resistant concrete material capable of effectively resisting fire damage, oxidized steel slag is acidized to serve as coarse aggregate, waste glass fine aggregate is treated by polystyrene to partially replace river sand fine aggregate, all the components are mixed in proportion, and a novel air entraining agent is doped to prepare high-temperature-resistant concrete. Compared with the traditional high-temperature-resistant concrete, the high-temperature-resistant concrete has the advantages of lower initial slump fluidity and slump fluidity retentivity, higher gas content, higher mechanical property, higher hardening density, higher water absorption rate and lower alkali-silicic acid reaction expansion value. The use of the novel air entraining agent and the high-temperature melting of polystyrene improve the anti-bursting ability and mechanical property residual rate of the concrete, and reduce the generation and development of burnt concrete cracks, the weight loss rate and the carbonization depth. According to the method for preparing the high-temperature-resistant concrete, the application range of wastes is expanded, the fire damage resistance of the concrete is improved, and good technical, economic, social and environment-friendly benefits can be generated.
本发明公开了一种能有效抵抗火灾破坏的耐高温型混凝土材料制备方法及产品应用，将氧化钢渣酸化处理作为粗骨料，废弃玻璃细骨料经聚苯乙烯处理后部分取代河砂细骨料，按比例混和各组分并掺加新型引气剂制备出耐高温混凝土。此种耐高温混凝土具有比传统耐高温混凝土更小初始塌落流动度和塌落流动度保持性、更大的含气量、力学性能、硬化密度和吸水率、更低的碱硅酸反应膨胀值。新型引气剂的使用和聚苯乙烯的高温融化，提高了混凝土的防爆裂能力和力学性能残余率，减少了烧损混凝土裂缝产生发展、重量损失率、碳化深度。此种制备耐高温混凝土方法扩大了废弃物应用范围，提高了混凝土抵抗火灾破坏的能力，能产生良好的技术、经济、社会和环保效益。
