Regenerated plastic fiber regenerated self-compacting concrete and preparation method thereof
The invention discloses regenerated plastic fiber regenerated self-compacting concrete and a preparation method thereof. The concrete is prepared from the following components: cement, recycled coarse aggregate, natural coarse aggregate, sand, water, additional water, mineral admixtures (coal ash, mineral powder and silica fume), recycled plastic PET (Polyethylene Terephthalate) fibers and an additive, wherein the replacement rate of the recycled coarse aggregate is 50-100%; and the substitution rate of the mineral admixture is 50-75%. According to the invention, wastes are used for treating wastes, so that the obtained concrete not only can obviously improve the strength and toughness of the concrete, but also can reduce the consumption of non-renewable natural resources and cement, effectively solves the difficult problem of treatment of waste concrete and plastic garbage and environmental pollution caused by the difficult problem, and realizes high performance of the recycled aggregate; the sustainable development capability of the fiber concrete and the self-compacting concrete is improved, and the important requirements of future development of low-carbon buildings, environmental protection and the like are met.
本发明公开了一种再生塑料纤维再生自密实混凝土及其制备方法。所述混凝土的组分如下：水泥、再生粗骨料、天然粗骨料、砂、水、附加水、矿物掺和料(粉煤灰、矿粉、硅灰)、再生塑料PET纤维、外加剂，其中再生粗骨料取代率为50％‑100％；矿物掺和料取代率为50％‑75％。本发明“以废治废”，所得混凝土不仅可以显著提高混凝土的强度和韧性，还可以减少不可再生自然资源及水泥的消耗，有效解决废弃混凝土和塑料垃圾处理难题及其引发的环境污染，实现再生骨料的高性能化，提升纤维混凝土和自密实混凝土的可持续发展能力，满足低碳建筑、环境保护等未来发展的重大需求。
