Embodiment 1
[0022] A special mortar for making aerated bricks, made of the following substances by weight:
[0023] 33 parts of cement, 40 parts of quartz sand, 10 parts of fly ash, 4 parts of modified starch, 3 parts of hollow glass microspheres, 0.3 parts of redispersible latex powder, 2 parts of sodium benzoate, and 4 parts of additives.
[0024] Further, the quartz sand SiO 2 The content is above 98%, and it has been processed through the following steps:
[0025] (1) Soak the quartz sand in hydrochloric acid with a mass fraction of 3 times its mass and 25% for 30 minutes, then take it out and rinse it with deionized water until neutral;
[0026] (2) After the washed quartz sand is calcined at 650~750°C for 3 hours, take it out and cool it to room temperature;
[0027] (3) After the calcined quartz sand is crushed and sieved, 100% of it can pass 60 mesh, and more than 60% of it can pass 100 mesh.
[0028] Further, the cement is slag portland cement.
[0029] Further, the modified ...

Abstract
The invention discloses special mortar used for preparing aerated bricks. The special mortar is prepared from, by weight, 30-35 parts of cement, 30-40 parts of quartz sand, 10-15 parts of coal ash, 4-6 parts of modified starch, 3-5 parts of hollow glass micro-beads, 0.2-0.5 parts of redispersible emulsion powder, 1-3 parts of sodium benzoate and 2-4 parts of auxiliaries. The quartz sand is pre-processed specially, the starch is modified cross-linked starch, the mortar and products prepared from the mortar have good heat preservation performance, sound silencing performance, fire-resistance performance and corrosion-resistant performance through cooperation with the functions of the remaining component and meanwhile have high compression resistance, high anti-shearing performance and other mechanical properties, comprehensive characteristics are greatly improved compared with similar products in the market, high competitiveness is achieved, and the special mortar used for preparing aerated bricks is worthy of popularization.
Description
technical field [0001] The invention relates to a mortar, in particular to a special mortar for making aerated bricks. Background technique [0002] Aerated bricks are aerated bricks produced by high-temperature autoclaved equipment, that is, bricks produced by various other processes including autoclaved. It is unique in that it is a very light thermal insulation Hot new building wall materials. The biggest advantage of aerated bricks is to save land resources, without wasting a lot of cultivated land. Its raw materials are widely used. Ash sand, slag, fly ash and coal gangue are all raw materials for aerated bricks. After mixing the raw materials into mortar, Then through the molding process to make aerated bricks. At present, the composition and properties of the mortar prepared by most manufacturers are not perfect, resulting in defects such as low strength, easy to burst, weak water resistance, and poor temperature resistance in the manufactured aerated bricks. The pr...
