Water permeable brick and preparation method thereof
The invention provides a water permeable brick and a preparation method thereof. The water permeable brick comprises the following components: aggregate, Portland cement, polypropylene fiber and an additive. Wherein the aggregate is prepared by crushing and sieving waste concrete, coal cinder and gravel through a crusher, so that building pollution sources are reduced, and the resource utilization rate is increased; the polypropylene fiber is modified by the silane coupling agent, so that the compressive strength of the water permeable brick is improved on the premise of ensuring the water permeability; the glass powder in the admixture can make up the defect of poor fluidity of the polypropylene fiber water permeable brick. The aggregate water permeable brick disclosed by the invention is high in strength, capable of bearing loads of medium-sized vehicles, good in water permeability and relatively high in flowability.
本发明提出了一种透水砖及其制备方法，包括如下组分：骨料、硅酸盐水泥、聚丙烯纤维和外加剂。其中骨料选取废弃混凝土、煤渣和碎石，经破碎机破碎过筛而成，减少建筑污染源，提高资源利用率；而聚丙烯纤维经硅烷偶联剂改性而成，保证透水性的前提下，提高了透水砖抗压强度；外加剂中的玻璃粉能弥补聚丙烯纤维透水砖流动性差的不足。本发明的骨料透水砖强度高，可承受中型车辆载荷，同时透水性好，流动性较强。
