High-strength recycled concrete and preparation method thereof
The invention provides high-strength recycled concrete and a preparation method thereof, and relates to the technical field of concrete. By adjusting the mix proportion of the recycled concrete and combining with surface modification of the recycled coarse aggregate, the problems of excessive edges and corners of recycled aggregate particles, overlarge proportion of needle-like substances, excessive internal fine cracks and the like are solved, and the strength of the recycled concrete is remarkably improved.
本发明提供了一种高强度再生混凝土及其制备方法，涉及混凝土技术领域。本发明通过调整再生混凝土的配合比结合再生粗骨料的表面改性，克服了再生骨料颗粒棱角过多、针状物占比过大、内部细微裂纹过多等问题，显著提高了再生混凝土的强度。
