Environment-friendly pervious concrete and preparation method thereof
The invention discloses environment-friendly pervious concrete and a preparation method thereof. The environment-friendly pervious concrete is prepared from cement, water, coarse aggregate, fine aggregate, an admixture, an additive, a coloring agent and thickening powder. The preparation method comprises the following steps: mixing the cement and the water and then stirring the mixture to be uniform to form cement paste; sequentially adding the coarse aggregate, the fine aggregate and the admixture into the cement paste in the step 1, and fully stirring and mixing to form an initial mixture; mixing an additive and a coloring agent together, adding the mixture into the initial mixture obtained in the step 2, and stirring and mixing the mixture to form a secondary mixture; putting the secondary mixture obtained in the step 3 on a concrete vibration table, and adding thickening powder to form a three-stage mixture; moving out the three-stage mixture in the concrete vibration table to formthe environment-friendly pervious concrete. In the invention, the reasonable coarse aggregate is selected and the fine aggregate is properly added, so that the preparation proportion of the environment-friendly pervious concrete is ensured, and the excellent pervious performance of the concrete is achieved.
本发明公开了一种环保型透水混凝土及其制备方法，该环保型透水混凝土包括水泥、水、粗集料、细集料、掺合料、添加剂、染色剂和增稠粉，其制备方法包括如下步骤：将水泥和水一起混合后并搅拌均匀形成水泥浆；依次向步骤一中的水泥浆加入粗集料、细集料和掺合料并充分搅拌混合，形成初始拌合料；将添加剂和染色剂混合在一起并加入步骤二中的初始拌合料中，搅拌混合后形成二级拌合料；将步骤三中的二级拌合料放到混凝土振动台上，并加入增稠粉，形成三级拌合料；将混凝土振动台中的三级拌合料取出，形成环保型透水混凝土，通过选择合理的粗集料、适当添加细集料，确保环保型透水混凝土的配置比例，实现混凝土优异的透水性能。
