Method for preparing recycled concrete based on activated water and recycled concrete
The invention relates to the technical field of recycled concrete preparation, and discloses recycled concrete prepared on the basis of activated water, the recycled concrete is prepared from recycled concrete aggregate, recycled concrete cement, activated water, natural gravel and an anti-freezing water reducing agent, and the ratio of the recycled concrete aggregate to the recycled concrete cement to the natural gravel to the activated water to the anti-freezing water reducing agent is 15: 4: 1.9: 1.5: 3-13: 3.7: 2.2: 1.9: 2.4. According to the recycled concrete prepared on the basis of activated water, waste concrete is crushed and screened to form coarse and fine aggregate to replace a stone part in traditional concrete, and meanwhile, cement components are prepared from micro powder generated by the fine aggregate, brick-mixed micro powder, waste concrete powder, slag powder and steel slag powder, so that the overall utilization rate of the waste concrete is increased; meanwhile, the effect of destroying intermolecular hydrogen bonds is achieved by adding the additive water and applying electric field energy through water, and meanwhile, by adding the anti-freezing water reducing agent, the anti-freezing property of the recycled concrete can be enhanced, and the cracking condition is reduced.
本发明涉及制备再生混凝土技术领域，且公开了基于活化水制备再生混凝土，包括：再生混凝土骨料、再生混凝土水泥、活性水、天然砂石和防冻减水剂，所述再生混凝土骨料、再生混凝土水泥、天然砂石、活性水和防冻减水剂的比例为15：4：1.9：1.5:3至13:3.7:2.2:1.9:2.4，该基于活化水制备再生混凝土，通过废弃混凝土采用破碎筛选形成粗细骨料，替代传统混凝土中的石料部分，同时水泥成分通过细骨料产生的微粉和砖混微粉、弃混凝土粉、矿渣粉、钢渣粉制备，提高整体的废弃混凝土利用率，同时通过添加性水，其通过水施加电场能量作用，以达到破坏分子间氢键的效果，同时通过添加防冻减水剂，可以增强再生混凝土的防冻性，减少开裂的情况发生。
