Solid waste-based ultra-high performance concrete dry blend and preparation method thereof
The invention discloses a solid-waste-based ultra-high-performance concrete dry blend and a preparation method thereof, belongs to the field of concrete, and solves the inherent problems of large raw material fluctuation, large performance fluctuation, non-uniform regulation and control methods and means and the like in the preparation process of the ultra-high-performance concrete dry blend. The invention relates to a solid waste-based ultra-high performance concrete dry blend, which comprises any one of C100, C120 and C140 solid waste-based ultra-high performance concrete dry blends, and comprises the following components: cement, superfine fly ash, silica fume, a core admixture, quartz sand, steel fiber and a viscosity reduction powder water reducer. The preparation method comprises the following steps: premixing powder; homogenizing the powder; and fiber dispersion. According to the invention, a series of three solid-waste-based ultra-high-performance concrete dry blends with the same material types, excellent construction performance and stepped rising strength indexes are successfully formed by designing and regulating the solid-waste-based ultra-high-performance concrete mix proportion, the admixture, the fiber and the functional core admixture, and convenient production in factories can be realized.
本发明公开了一种固废基超高性能混凝土干混料及其制备方法，属于混凝土领域，解决了超高性能混凝土干混料制备过程中原材料波动大、性能波动大、调控方法手段不统一等固有问题。一种固废基超高性能混凝土干混料，包括：C100、C120、C140固废基超高性能混凝土干混料中的任意一种，组分如下：水泥、超细粉煤灰、硅灰、核心掺合料、石英砂、钢纤维、降粘粉体减水剂。制备方法：粉体预混；粉体均化；纤维分散。本发明通过固废基超高性能混凝土配合比、外加剂、纤维和功能性核心掺合料设计和调控，成功形成材料种类相同、施工性能优异、强度指标阶梯式上升的一系列三种固废基超高性能混凝土干混料，可实现工厂便捷生产。
