Green carbon-reducing concrete admixture, green carbon-reducing concrete and preparation method
The invention belongs to the technical field of building materials, and discloses a green carbon-reducing concrete admixture, green carbon-reducing concrete and a preparation method. When the admixture prepared from the double-doped water reducing agent and the expanding agent as main materials and the graphene oxide, the air entraining agent and the natural fibers as auxiliary materials is applied to concrete, the anti-freezing property of the concrete can be remarkably improved, the toughness of the concrete can be improved while the mechanical property of the concrete is fully guaranteed, and meanwhile, the anti-freezing performance of the concrete is improved. When the concrete is prepared, waste industrial mineral powder such as slag and steel slag is used for replacing cement, so that the use amount of the cement is reduced, the emission of carbon dioxide is indirectly reduced, and the concrete has good social value and economic value.
本发明属于建筑材料技术领域，本发明公开了一种绿色减碳混凝土外加剂、绿色减碳混凝土及制备方法。本发明以双掺减水剂和膨胀剂为主料，再辅以氧化石墨烯、引气剂和天然纤维制备的外加剂应用在混凝土中时，不仅能够显著提高混凝土的抗冻性能，而且能够在充分保证混凝力学性能的同时提高混凝土的韧性，同时，本发明制备混凝土时利用矿渣、钢渣等废弃工业矿粉替代水泥，减少了水泥的用量，间接降低了二氧化碳的排放，具有良好的社会价值和经济价值。
