Environment-friendly pervious concrete and preparation method thereof
The invention belongs to the technical field of building materials, and particularly relates to environment-friendly pervious concrete and a preparation method thereof. The environment-friendly pervious concrete is prepared from the following components in parts by mass: 200 to 300 parts of cement, 100 to 200 parts of medium sand, 50 to 150 parts of aggregate, 3.5 to 5 parts of modified bamboo leaf fiber, 8 to 15 parts of carboxylic butadiene-acrylonitrile latex, 3 to 4 parts of silane coupling agent and 100 to 200 parts of water, the modified bamboo leaf fibers are subjected to surface modification through a siloxane polymer; the modified bamboo leaf fiber, the silane coupling agent and the carboxylic butadiene-acrylonitrile latex have a good compatibility effect, and the compressive strength, the splitting tensile strength and the permeation coefficient of the environment-friendly pervious concrete are enhanced.
本发明属于建筑材料技术领域，具体来说涉及一种环保透水混凝土及其制备方法。其中，一种环保透水混凝土，以质量份计，包括200‑300份的水泥、100‑200份的中砂、50‑150份的骨料、3.5‑5份的改性竹叶纤维，8‑15份的羧基丁腈胶乳，3‑4份的硅烷偶联剂及100‑200份的水；改性竹叶纤维经硅氧烷聚合物进行表面改性；改性竹叶纤维、硅烷偶联剂及羧基丁腈胶乳之间具有较好的配伍效果，增强了环保透水混凝土的抗压强度、劈裂抗拉强度及透水系数。
