Industrial waste pervious concrete and preparation method thereof

ZHANG CHENGGONG

The invention discloses industrial waste pervious concrete and a preparation method thereof. The industrial waste pervious concrete is prepared from the following components: cement, siliceous sand grains, barren rock, fly ash, water, a water reducing agent, lightweight aggregate, triethanolamine and polypropylene fibers. The preparation method comprises the following steps: crushing industrial waste; selecting raw materials; preparing fly ash ceramsite; preparing a lightweight aggregate; preparing an additive; stirring and mixing. According to the pervious concrete disclosed by the invention, the fly ash and the barren rock are added into the raw materials for preparing the concrete, so that industrial wastes generated by a thermal power plant can be recycled, and the strength and the adaptability of the pervious concrete can be enhanced; the polypropylene fibers can increase the strength of the concrete and enable the concrete to become wear-resistant and corrosion-resistant, triethanolamine is used as a medium, and the polypropylene fibers can be uniformly mixed with other materials of the concrete, so that the concrete with good water permeability is better in water permeability, higher in strength and longer in service life.

本发明公开了一种工业废弃物透水混凝土及其制备方法由以下成分组成：水泥、硅质砂粒、废石、粉煤灰、水、减水剂、轻骨料、三乙醇胺、聚丙烯纤维，包括如下步骤：工业废弃物的粉碎；选择原料；粉煤灰陶粒的制备；轻骨料的制备；外加剂制备；搅拌混合。在制备混凝土的原材料中加入了粉煤灰与废石，既能够回收火电厂产生的工业废弃物，又可以使该透水混凝土的强度与适应性增强，制备混凝土时，向搅拌装置的内部添加三乙醇胺与聚丙烯纤维，聚丙烯纤维可以以使该混凝土的强度增加并可以使该混凝土变得耐磨、耐腐蚀，三乙醇胺作为介质，可以使聚丙烯纤维均匀的与混凝土的其它材料进行混合，使该透水性好的混凝土透水性更好，且强度更高、使用寿命增加。
