High-strength and high-toughness reinforced concrete composite component and preparation method thereof
The invention relates to a high-strength and high-toughness reinforced concrete composite component and a preparation method thereof. The composite component comprises a concrete body and reinforcing steel bars arranged in the concrete body, the concrete body comprises two recycled aggregate high-strength and high-toughness reinforced concrete layers and a concrete layer arranged between the two recycled aggregate high-strength and high-toughness reinforced concrete layers; the preparation method of the composite component comprises the following steps: selecting recycled aggregate, screening according to different particle sizes of the recycled aggregate, forming recycled fine aggregate according to particle size distribution configuration, and mixing matrix neat paste of the recycled aggregate high-strength and high-toughness reinforced concrete, the recycled fine aggregate and chopped fibers to prepare the recycled aggregate high-strength and high-toughness reinforced concrete. According to the high-strength and high-toughness reinforced concrete composite component and the manufacturing method thereof, the problems that an existing high-strength and high-toughness reinforced concrete component integrally needs to use fine quartz sand as a raw material, the price is high, and sustainable mining cannot be provided are solved.
本发明涉及一种高强高韧钢筋混凝土复合构件及其制备方法，复合构件包括混凝土本体和设置于混凝土本体内的钢筋，混凝土本体包括两个再生骨料高强高韧钢筋混凝土层及设置在两个再生骨料高强高韧钢筋混凝土层中间的混凝土层；复合构件的制备方法包括：选取再生骨料，根据再生骨料的不同粒径进行筛分，根据粒径分布配置形成再生细骨料，将再生骨料高强高韧钢筋混凝土的基体净浆、再生细骨料和短切纤维混合，制备形成再生骨料高强高韧钢筋混凝土，制作复合构件模具，固定钢筋浇筑模具形成高强高韧钢筋混凝土复合构件，本发明旨在解决现有高强高韧钢筋混凝土构件整体需要使用精细石英砂作为原材料，价格昂贵，无法提供可持续性开采的问题。
