Preparation method of baking-free brick with high breaking strength
The invention discloses a preparation method of a baking-free brick with high breaking strength. The method relates to the technical field of baking-free bricks, and comprises the following steps: (1)dipping treatment on fly ash, namely carrying out dipping treatment on the fly ash by adopting an ammonium dihydrogen phosphate solution for 40 minutes, and then filtering and drying to obtain dippedfly ash; (2) heat treatment: carrying out heating treatment on the impregnated fly ash at the heating temperature of 700-800 DEG C, carrying out heat preservation for 2 hours, and then naturally cooling to room temperature to obtain heat-treated fly ash; (3) clay treatment: mixing clay with a sodium silicate solution to obtain composite clay; and (4) mixing the composite clay and the heat-treatedfly ash, carrying out compression molding, and drying to constant weight, thereby obtaining the product. The invention discloses a preparation method of a baking-free brick with high breaking strength. The baking-free brick prepared by the method has excellent mechanical properties.
本发明公开了一种高抗折强度的免烧砖制备方法；涉及免烧砖技术领域，包括以下步骤：（1）对粉煤灰进行浸渍处理：将粉煤灰采用磷酸二氢铵溶液浸渍处理40min，然后进行过滤，烘干，得到浸渍粉煤灰；（2）热处理：将经过浸渍处理的粉煤灰进行加热处理，加热温度为700‑800℃，保温2小时，然后再自然冷却至室温，得到热处理粉煤灰；（3）黏土处理：将黏土与硅酸钠溶液进行混合，得到复合黏土;（4）将复合黏土、热处理粉煤灰混合后，进行压制成型，然后烘干至恒重，即得；本发明方法公开了一种高抗折强度的免烧砖制备方法，本发明方法制备的免烧砖具有优异的力学性能。
