PENG JIANXIONG / ZHAO SUBO / CHEN XIAOFEI

The invention discloses environment-friendly high-strength lightweight concrete and a preparation method thereof, belongs to the technical field of concrete manufacturing methods, and discloses EPS lightweight concrete which is novel functional concrete integrating energy conservation, environmental protection, light weight and excellent heat preservation and heat insulation. The defects of large dead weight, poor heat insulation performance and the like of traditional concrete can be overcome; a basic material is provided for a high-rise, light-weight and fabricated enclosure structure of a building, the indoor comfort level of the building is effectively improved, and the energy consumption of the building is reduced. The EPS particles used in the invention are obtained by recycling the waste polystyrene foam, and the regenerated EPS and the concrete are combined, so that multiple effects of light weight, heat insulation, shock resistance and energy absorption of the building envelope structure can be realized, the problem of white pollution of the waste EPS foam can be solved, and the requirements of energy conservation, waste utilization and environmental protection are met. Therefore, the technical problem of how to enable the EPS concrete to realize light weight, high specific strength, low heat conductivity coefficient and green function is solved.

本发明公开了一种环保高强度轻质混凝土及其制备方法，其属于混凝土制造方法的技术领域，本发明所揭示的EPS轻质混凝土是一种集节能环保、轻质及优保温隔热于一体的新型功能性混凝土，可解决传统混凝土自重大、保温隔热性能差等缺点；为建筑物高层化、轻质化及装配式围护结构提供了基础材料，有效提高建筑室内舒适度和降低建筑能耗。本发明所使用的EPS颗粒由废弃聚苯乙烯泡沫资源化回收再利用而得，再生EPS与混凝土祸合不仅能实现建筑围护结构轻量化、保温隔热和抗震吸能多重功效，还能解决废弃EPS泡沫的白色污染问题，实现节能利废与绿色环保要求。所以，本发明解决了如何令EPS混凝土实现轻质高比强、低导热系数以及绿色功能的技术问题。
