Chloride ion erosion resistant recycled coarse and fine aggregate concrete and preparation method thereof
The invention relates to the technical field of concrete, in particular to chloride ion erosion resistant recycled coarse and fine aggregate concrete and a preparation method thereof. The chloride ion permeability resistance of recycled aggregate concrete prepared by a conventional method is poor. In order to solve the problems, the invention provides the recycled coarse and fine aggregate concrete resistant to chloride ion corrosion, which is prepared by the following steps: premixing and stirring recycled coarse aggregate, recycled fine aggregate, natural gravel and natural sand to form an aggregate mixture, soaking the aggregate mixture in water, so that the aggregate mixture fully absorbs water to obtain a pre-impregnated aggregate mixture, and curing the pre-impregnated aggregate mixture to obtain the recycled coarse and fine aggregate concrete resistant to chloride ion corrosion. According to the process, the pre-impregnated aggregate mixture is uniformly mixed with other raw materials, so that the obtained concrete has better chloride ion corrosion resistance, and meanwhile, the strength and durability of the obtained concrete in the construction process are ensured by accurately controlling the effective water-binder ratio.
本发明涉及混凝土技术领域，具体涉及一种耐氯离子侵蚀的再生粗细骨料混凝土及其制备方法。常规方法制备的再生骨料混凝土的抗氯离子渗透性较差。针对上述问题，本发明提供一种耐氯离子侵蚀的再生粗细骨料混凝土，其先将再生粗骨料、再生细骨料、天然碎石、天然砂预混搅拌形成的骨料拌合料，再在水中浸润，使得骨料拌合料充分吸水后，得到预浸骨料拌合料，再将预浸骨料拌合料与其他原料混合均匀，该工艺使得所获混凝土具有更好的耐氯离子侵蚀性能，同时，通过精确控制有效水胶比，确保了所获混凝土在施工过程中强度和耐久性。
