High-strength pervious concrete admixture and pervious concrete
The invention relates to the technical field of concrete admixtures, and discloses a high-strength pervious concrete admixture and pervious concrete. The high-strength pervious concrete admixture is composed of, by weight, 1-2% of a water reducing agent, 1-2% of a dispersing agent, 10-15% of paraffin, 20-30% of asbestos wool, 2-3% of redispersible latex powder, 1-2% of an active agent and 1-2% of butyl stearate. The specific method comprises the following steps: step 1, placing asbestos wool in a high-speed stirrer and conducting stirring for 5-10 min in the environment of the high-speed stirrer at the temperature of 160-200 DEG C so as to disperse and expand the asbestos wool. According to the high-strength pervious concrete admixture and the pervious concrete, the concrete has good water permeability and good air permeability through preparation of the high-strength pervious concrete admixture, and the strength and wear resistance of the concrete are guaranteed while the porosity and the water permeability of the pervious concrete are improved through addition of cellulose.
本发明涉及混凝土外加剂技术领域，且公开了一种高强透水混凝土外加剂及透水混凝土，包括以下重量比的原料组成：减水剂1～2％、分散剂1～2％、石蜡10～15％、石棉戎20～30％、可再分散乳胶粉2～3％、活性剂1～2％、硬脂酸丁酯1～2％，具体方法步骤如下：步骤一，石棉戎置于高速搅拌机中，在高速搅拌机160‑200℃的环境中进行搅拌5‑10min使其分散、膨胀。该种高强透水混凝土外加剂及透水混凝土，通过高强透水混凝土外加剂的制作，使的混凝土具有良好的透水性和良好的透气性，通过纤维素的添加，提升了透水混凝土孔隙率和透水量的同时，还保证了混凝土的强度、耐磨性。
