Curing process for improving strength of clay bricks
The invention discloses a curing process for improving the strength of clay bricks. The curing process comprises the following steps of: S1, removal of impurities in sludge: removing tree branches, household garbage, stones and the like through a vibration stirrer; S2, filter pressing of the sludge, thereby finally obtaining sludge with a water content of less than or equal to 60 percent; S3, addition of coal ash and fine sand: adding the coal ash and the fine sand into the sludge, wherein a mass ratio of the coal ash to the fine sand to the sludge is 5: 3: 1, uniformly mixing the coal ash, the fine sand, the sludge, and carrying out stirring; S4, addition of a curing agent: adding the curing agent which contains 0.3% of a waterproof agent, continuing stirring, and rolling a stirred material; S5, molding: adding the stirred material into a mold, and conducting molding in a bench mold resonance brick machine; S6, maintenance: conducting curing for specified days in a curing chamber withset standard temperature and humidity to obtain a cured green body; and S7, detection of the strength and the pressure resistance of the clay bricks, wherein finished products are obtained if the clay bricks are detected to be qualified. The process can be used for producing the clay bricks with higher strength and long service life, so the resource reutilization of solid wastes is realized.
本发明公开了一种提高泥土砖强度的固化工艺，包括以下步骤：S1.去除淤泥中杂质，将树木枝干、生活垃圾、石块等，通过振动搅拌机剔除，S2.对淤泥进行压滤，最终得到含水率≤60％的淤泥；S3.掺加粉煤灰、细砂，在淤泥中掺加粉煤灰、细砂，淤泥、粉煤、细砂灰质量比为5：3：1，三者混合均匀，并进行搅拌，S4.添加固化剂，添加固化剂，固化剂中含有0.3％的防水剂，继续搅拌，并对搅拌物进行辗压，S5.成型，将搅拌物加入模具，在台模共振砖机中成型，S6.养护，在设定标准温湿度的养护室中，养护规定天数，得固化坯体，S7.检测对泥土砖强度、抗压性进行检测，合格后获得成品。本发明可以生产强度较高的泥土砖，使用寿命长，实现固体废弃物的资源化再利用。
