Anti-crack pervious concrete and preparation method thereof
The embodiment of the invention is suitable for the technical field of building materials, and provides anti-crack pervious concrete and a preparation method thereof. The anti-crack pervious concrete is prepared from the following raw materials in parts by weight: 20 parts of cement, 7 parts of water seepage filler, 0.4 part of reinforced fiber, 90 parts of recycled aggregate, 20 parts of water, 3 parts of a water reducing agent, 3.5 parts of welan gum, 2.5 parts of a thickening agent, 11 parts of isopropanolamine and 4 parts of modified siloxane. The invention also provides a preparation method of the anti-crack pervious concrete, and the preparation method comprises the following steps: weighing the cement, a water infiltration filler, reinforced fibers, recycled aggregate and water in parts by weight, putting the weighed materials into a mixing tank, and uniformly conducting stirring; and then weighing a water reducing agent, welan gum, a thickening agent, isopropanolamine and modified siloxane in parts by weight, and uniformly conducting mixing to obtain the anti-crack pervious concrete. The anti-crack pervious concrete provided by the embodiment of the invention effectively solves the problems that the existing pervious concrete is relatively low in self strength and cannot meet the use requirements of high strength and quick water permeability at the same time.
本发明实施例适用于建筑材料技术领域，提供了一种抗裂透水混凝土及其制备方法，所述的抗裂透水混凝土包括以下按重量份组成的原料：水泥20份、渗水填料7份、增强纤维0.4份、再生骨料90份、水20份、减水剂3份、温轮胶3.5份、增稠剂2.5份、异丙醇胺11份和改性硅氧烷4份。还提供了一种抗裂透水混凝土的制备方法，所述的制备方法包括以下步骤：按重量份称取水泥、渗水填料、增强纤维、再生骨料和水，并投入到混合罐内搅拌均匀；然后按重量份称取减水剂、温轮胶、增稠剂、异丙醇胺和改性硅氧烷并混合均匀制得抗裂透水混凝土。本发明实施例提供的抗裂透水混凝土有效解决了现有的透水混凝土，自身强度较低，无法同时兼顾高强度和快透水的使用要求的问题。
