Coal gangue pervious concrete and preparation method thereof
The invention discloses coal gangue pervious concrete and a preparation method thereof, and is characterized in that the coal gangue pervious concrete is prepared from the following materials: coal gangue aggregate, cement, silica fume, water, nano silicon dioxide, a liquid type superplasticizer and a powder type superplasticizer; the preparation method comprises the following steps: S1, preparing materials; s2, washing and stirring the coal gangue in the sun to obtain treated coal gangue I; s3, adding cement, silica fume and water to obtain treated coal gangue II; s4, adding nano silicon dioxide, a high-efficiency water reducing agent and water to obtain the coal gangue pervious concrete; and S5, discharging and mold filling are conducted, manual inserting and tamping treatment is conducted, pouring is conducted in three layers, after pouring of each layer is completed, inserting and tamping are evenly conducted from the edge to the center through a stick, and standard curing is conducted after demolding is conducted. According to the present invention, the scientific ratio and the preparation process are combined, such that the strength of the coal gangue pervious concrete is improved, the resource utilization of the coal gangue building material is achieved, and the secondary energy consumption is reduced.
本发明公开了一种煤矸石透水混凝土及其制备方法，其特征在于，其是由如下材料制成：煤矸石骨料、水泥、硅灰、水、纳米二氧化硅、液体型高效减水剂、粉末型高效减水剂；其制备方法包括以下步骤：S1：准备材料；S2：对煤矸石晒洗与搅拌，得到处理后的煤矸石一；S3：加入水泥、硅灰以及水，得到处理后的煤矸石二；S4：加入纳米二氧化硅和高效减水剂以及水，得到煤矸石透水混凝土；S5：出料装模，人工插捣处理，分三层进行浇筑，每层浇筑完成之后，从边缘到中心用棍棒均匀插捣，脱模后进行标准养护。本发明通过科学的配比与制备工艺结合，提高了煤矸石透水混凝土的强度、实现煤矸石建筑材料资源化利用，同时减少了二次能耗。
