Abstract

The invention relates to fireproof mortar prepared from waste bricks and tiles and a preparation method of the fireproof mortar, and belongs to the field of building materials, the fireproof mortar comprises the following components in parts by weight: 400-500 parts of cementing material, 100-280 parts of vermiculite aggregate, 200-400 parts of vitrified waste brick and tile aggregate, 7-10 parts of cellulose, 2-5 parts of water reducing agent and 2-4 parts of tackifier; the granularity of the vitrified waste brick and tile aggregate is 0.5-1.5 mm, and the stacking area is 70-80 kg/m3; vitrified waste brick and tile aggregate and vermiculite aggregate are used as mortar aggregate, Portland cement or aluminate cement is used as a cementing material, resource utilization of the waste bricks and tiles can be achieved, and the problems of environmental pollution, resource and energy consumption and the like caused by the waste bricks and tiles are relieved to the maximum extent; and waste bricks and tiles are crushed and processed to prepare waste brick and tile particles, and the specific surface area and porosity of the waste brick and tile particles are increased through hydrochloric acid acidification, so that the thermal conductivity of the waste brick and tile particles is reduced, and the fireproof performance of mortar is effectively improved.

Description

technical field [0001] The invention belongs to the field of building materials, and in particular relates to a fireproof mortar prepared from waste bricks and tiles and a preparation method thereof. Background technique [0002] With the continuous acceleration of the socialization process, the construction industry is also developing rapidly. At the same time, people's pursuit of a higher level of quality of life is also increasing day by day, and building mortar with thermal insulation properties is also popularized. Mortar is mostly organic material with unstable physical and chemical properties, which is easy to cause fire, causing greater casualties and property losses. With the continuous enhancement of people's safety awareness, fireproof mortar is gradually favored by the construction industry. The current fireproof mortar is mainly made of some natural stone, but these natural stone reserves are insufficient, so the shortage of natural stone resources has become a ...
