High-compactness sand washing mud baking-free brick and preparation method thereof
The invention belongs to the technical field of building materials, and particularly discloses a high-compactness sand washing mud baking-free brick and a preparation method thereof.The high-compactness sand washing mud baking-free brick is prepared from 60-90 parts of sand washing mud, 10-30 parts of stone powder, 5-20 parts of cement, 1-5 parts of slaked lime, 0.1-1 part of redispersible latex powder and 5-10 parts of water.The preparation method comprises the steps that firstly, the sand washing mud, the stone powder, the cement, the slaked lime and the redispersible latex powder are subjected to dry mixing; then spraying water into the dry mixture until a wet mixture with the moisture content within a certain accurate range is obtained, and finally pouring the wet mixture into a static pressure brick mold to be subjected to secondary static pressure molding under the pressure within a certain accurate range, the sand washing mud baking-free brick obtained through the method has the advantages of being high in strength, small in shrinkage, excellent in water resistance, low in carbon, environmentally friendly and remarkable in economic benefit on the whole, and has a good popularization prospect.
本发明属于建筑材料技术领域，具体公开一种高密实度洗砂泥免烧砖及其制备方法，所述免烧砖成分为洗砂泥60~90份、石粉10~30份、水泥5~20份、熟石灰1~5份、可再分散乳胶粉0.1~1份和水5~10份，制备过程，先将洗砂泥、石粉、水泥、熟石灰和可再分散乳胶粉干拌，接着喷洒水到干混合料中，直到获取含水率在一定精确范围的湿混合料，最后将湿混合料倒入到静压砖模具中在一定精确范围压力下二次静压成型，该方法获得的洗砂泥免烧砖整体上具有强度高、收缩小、耐水性优、低碳环保且经济效益显著的特点，具有较好的推广前景。
