Pervious concrete and preparation method thereof
The invention discloses pervious concrete and a preparation method thereof, and relates to the technical field of concrete. The pervious concrete comprises: 10-20 parts by weight of cement; 0.2-1 part by weight of an expanding agent; 0.1-0.5 parts by weight of polyacrylate; 60-80 parts by weight of a coarse aggregate; 1-5 parts by weight of an organic emulsion; 1-5 parts by weight of a three-dimensional fabric; and 0.2-1 part by weight of a superplasticizer. The preparation method of the pervious concrete is simple, and the pervious concrete is convenient to construct. The problem of poor anti-freezing and anti-cracking performance of pervious concrete in the prior art is solved, and the anti-freezing performance, compressive strength and breaking strength of the pervious concrete are improved.
本发明公开了一种透水混凝土及其制备方法，涉及混凝土技术领域，透水混凝土包括：10～20重量份的水泥；0.2～1重量份的膨胀剂；0.1～0.5重量份的聚丙烯酸盐；60～80重量份的粗骨料；1～5重量份的有机乳液；1～5重量份的三维织物；0.2～1重量份的高效减水剂，该透水混凝土制备方法简单，施工方便；本发明解决了现有技术中的透水混凝土存在抗冻抗裂性能较差的问题，实现了提高透水混凝土的抗冻性能、抗压强度和抗折强度的技术效果。
