Recycled concrete prepared from steel slag and recycled aggregate
The invention relates to the field of recycled concrete, in particular to recycled concrete prepared from steel slag and recycled aggregate. The preparation raw materials comprise steel slag and recycled aggregate, the steel slag is pretreated steel slag, the pretreatment comprises the steps of firstly soaking the steel slag in water and then carrying out high-temperature and high-pressure treatment, and the high-temperature and high-pressure treatment is carried out under the condition of autoclaving in a high-temperature closed environment with the pressure intensity of 1.8-2.2 MPa and the temperature of 160-200 DEG C. The steel slag and the recycled aggregate can be effectively combined to prepare the high-performance recycled concrete, waste resources are utilized, the raw material cost is saved, a test piece with high strength and high elastic modulus is prepared, environmental pollution is reduced, ecology is protected, and good economic and social benefits are achieved.
本发明涉及再生混凝土领域，尤其涉及一种钢渣与再生骨料制备的再生混凝土。其制备原料包括钢渣与再生骨料，所述钢渣为经预处理后的钢渣，所述预处理为：先浸泡于水中，然后高温高压处理，所述高温高压处理的条件为：在1.8‑2.2MPa压强和160‑200℃的高温封闭环境下蒸压。本发明可有效地将钢渣与再生骨料相结合制备高性能再生混凝土，既利用了废弃资源节约原材料成本，并制备出较高强度、较高弹性模量的试件，还减少环境污染，保护生态，具有良好的经济与社会效益。
