Reinforced recycled concrete aggregate and preparation method thereof
The invention relates to a preparation method of reinforced recycled concrete aggregate, which comprises the following steps: soaking superfine glass powder with the median particle size of 0.5-2 mu m in water for 24-48 hours to obtain superfine glass liquid; mixing the superfine glass liquid with concrete slurry slag, adding water to prepare slurry, and performing ultrasonic excitation to obtain reinforced slurry; and placing the recycled concrete aggregate in the reinforced slurry, and filtering to obtain the reinforced recycled concrete aggregate. The reinforced recycled concrete aggregate with a surface reinforced layer is obtained by mixing superfine glass liquid and concrete slurry residues to prepare reinforced slurry and carrying out slurry wrapping treatment on the recycled concrete aggregate by the reinforced slurry so as to repair micropores of mortar on the surface of the recycled concrete aggregate; compared with the unreinforced recycled concrete aggregate, the concrete prepared from the reinforced recycled concrete aggregate has higher compressive strength.
本申请涉及一种强化再生混凝土骨料的制备方法，包括：将中值粒径为0.5μm～2μm的超细玻璃粉末置于水中浸泡24～48h，以得到超细玻璃液；将超细玻璃液与混凝土浆渣混合，加水配置成浆液，超声激发以得到强化浆液；将再生混凝土骨料放置于强化浆液中，过滤以得到强化再生混凝土骨料。本发明通过超细玻璃液和混凝土浆渣混合制备出强化浆液，强化浆液对再生混凝土骨料进行裹浆处理，以对再生混凝土骨料表面砂浆的微孔隙进行修复，得到具有表面强化层的强化再生混凝土骨料；与未经强化的再生混凝土骨料相比，强化再生混凝土骨料制备的混凝土抗压强度更高。
