Concrete pavement brick prepared from graphite slag and preparation method thereof
The invention discloses a concrete pavement brick prepared from graphite slag and a preparation method thereof. Graphite slag, cement, an alkaline inorganic admixture, aggregate and fly ash are used as materials through a mature manufacturing technology, wherein the graphite slag in a base material layer is hydrated with an alkaline inorganic material, cement and fly ash to generate C-S-H gellingbodies, a water-resistant agent forms a film when meeting water, and capillary channels of hydrated ettringite are blocked, so that the compressive strength of the ettringite is high, the water invasion resistance is good, and the ettringite does not crack after being soaked in water; the graphite slag, cement, aggregate and a curing agent in the surface layer material are hydrated to form calciumsilicate gel, so that a relatively high toughening effect is achieved, and the wear resistance of the brick is improved under the cooperation of the aggregate. According to the patent technology, sintering-free normal-temperature curing molding is adopted, and special production equipment is not needed; the process flow is simple, the cost is low, and the graphite slag concrete pavement brick canbe used for sidewalks, roads, gardens, squares and the like.
本发明公开了一种石墨渣制备混凝土路面砖及其制备方法，利用石墨渣、水泥、碱性无机掺和料、骨料、粉煤灰为材料，制造技术成熟，基料层中石墨渣与碱性无机材料、水泥、粉煤灰在水化后，产生C‑S‑H胶凝体，耐水剂遇水成膜，堵塞水化后钙矾石的毛细通道，有较高的水泥石抗压强度，又有良好的抗水入侵能力，浸水后不开裂；面层料中石墨渣、水泥、骨料及固化剂水化形成硅酸钙胶凝体，具有较高的增韧效果，并在骨料配合下，增加砖的耐磨性能。本专利技术是采用免烧结常温固化成型，无需特殊生产设备；工艺流程简捷，成本便宜，石墨渣混凝土路面砖可用于人行道、马路、花园和广场等使用。
