Preparation method of high-strength recycled concrete
The invention relates to the technical field of recycled concrete, in particular to high-strength recycled concrete and a preparation method thereof. According to the scheme, waste concrete blocks are crushed, screened and subjected to surface strengthening treatment to obtain pretreated recycled coarse aggregate, the pretreated recycled coarse aggregate is mixed with cement, machine-made sand, fly ash, a water reducing agent, reinforced fibers and other components are added, and meanwhile a curing agent and resin mixed solution is introduced, so that cross-linking of a concrete system is improved; the comprehensive mechanical property of the concrete is improved. The invention discloses high-strength recycled concrete and a preparation method thereof, according to the scheme, a preparation process of recycled coarse aggregate is improved, the proportioning components of the concrete are adjusted, the prepared recycled coarse aggregate has low water absorption and crushing index, the mechanical strength of the concrete is also improved, and the concrete has high practicability.
本发明涉及再生混凝土技术领域，具体为一种高强度再生混凝土及其制备方法。在该混凝土中，方案以废旧混凝土块破碎筛分后表面强化处理，以得到预处理再生粗骨料，再将其与水泥混合，加入机制砂、粉煤灰、减水剂和增强纤维等组分，同时还引入了固化剂和树脂混合液，提高混凝土体系交联，以提高混凝土的综合力学性能。本发明公开了一种高强度再生混凝土及其制备方法，该方案对再生粗骨料的制备工艺进行改进，并调整了混凝土的配比组分，制备得到的再生粗骨料具有较低的吸水率和压碎指标，且混凝土的力学强度也得到改善，具有较高的实用性。
