Pervious concrete and preparation method thereof
The invention relates to the field of concrete, and particularly discloses pervious concrete and a preparation method thereof. The pervious concrete comprises the following raw materials: slag; cement; water; a polyamide resin; corn straw fibers; a water reducing agent; and an interface modifier. The preparation method comprises the following steps: taking part of corn straw fibers, crushing, adding polyamide resin and an interface modifier, and stirring for reaction to obtain a product A; and uniformly stirring and mixing slag, cement, water, residual corn straw fibers and a water reducing agent, then adding the product A, uniformly stirring and mixing, and cooling to room temperature to obtain the pervious concrete. According to the pervious concrete, the polyamide resin, the corn straw fibers, the interface modifier and the water reducing agent are adopted, the corn straw fibers reinforce the polyamide resin under the action of the interface modifier, the tensile strength and bending strength of the prepared pervious concrete are improved, and the water cement ratio is reduced by adding the water reducing agent, so that the strength of the prepared pervious concrete is comprehensively improved.
本申请涉及混凝土领域，具体公开了一种透水混凝土及其制备方法。透水混凝土包括如下原料：矿渣；水泥；水；聚酰胺树脂；玉米秸秆纤维；减水剂；界面改性剂；其制备方法为：取部分玉米秸秆纤维粉粹，加入聚酰胺树脂和界面改性剂搅拌反应，制得产物A；将矿渣、水泥、水、剩余的玉米秸秆纤维和减水剂搅拌混匀，接着加入产物A，搅拌混匀，冷却至室温，制得透水混凝土。本申请的透水混凝土采用聚酰胺树脂、玉米秸秆纤维、界面改性剂和减水剂，玉米秸秆纤维在界面改性剂的作用下对聚酰胺树脂进行增强，提高了制得的透水混凝土的拉伸强度和弯曲强度，减水剂的加入降低了水灰比，从而综合提高了制得的透水混凝土的强度。
