Inorganic stone slab containing recycled concrete aggregate and preparation method thereof
The invention discloses an inorganic stone slab containing recycled concrete aggregate and a preparation method thereof. The inorganic stone slab comprises the following components in parts by weight:30-60 parts of an inorganic cementing material, 2-15 parts of an inorganic mineral admixture, 20-55 parts of quartz sand, 35-60 parts of recycled concrete aggregate, 0.5-4 parts of a water reducing agent, 2-4 parts of an inorganic reinforcing agent and water for mixing. Waste concrete is used as aggregate, because of its high water absorbability, the concrete serves as an internal curing agent, pre-water-absorption treatment is carried out to reduce the shrinkage cracking risk of the inorganic stone; fortifier is cooperatively used for compensation of mechanical properties of aggregates, recycling of waste concrete can relieve environmental stress, and energy-saving, waste-utilizing, economical and environment-friendly effects can be achieved. The inorganic stone slab is reasonable in proportion design, simple in technological operation, economical, environmentally friendly, capable of effectively preparing the inorganic stone slab containing the recycled concrete aggregate, capable of improving the mechanical property and the crack resistance of the inorganic stone slab, uniform in component, compact in structure, high in practicability and suitable for being widely used and popularized.
本发明公开了一种含有再生混凝土骨料的无机石板材及其制备方法，该无机石板材包括以下重量组分：无机胶凝材料30‑60份、无机矿物掺合料2‑15份、石英砂20‑55份、再生混凝土骨料35‑60份、减水剂0.5‑4份、无机增强剂2‑4份和拌合用水。本发明利用废弃混凝土作为骨料，因其具有吸水性大，充当内养护剂，进行预吸水处理减少无机石收缩开裂风险，配以增强剂，弥补骨料的力学性能，废弃混凝土的再次利用，能够缓解环境压力，节能利废，经济环保，该无机石板材配比设计合理，工艺操作简单，不仅经济环保且有效制备了一种含有再生混凝土骨料的无机石板材，而且提高了无机石板材力学性能和抗裂性能，成分均匀，结构致密，具有较高实用性，适合广泛推广与使用。
