Fireproof mortar prepared from waste bricks and tiles and preparation method thereof
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.
本发明涉及一种利用废弃砖瓦制备的防火砂浆及其制备方法，属于建筑材料领域，本发明按重量份计包括：胶凝材料400‑500份、蛭石骨料100‑280份、玻化废弃砖瓦骨料200‑400份、纤维素7‑10份、减水剂2‑5份、增粘剂2‑4份；所述的玻化废弃砖瓦骨料粒度为0.5‑1.5mm，堆积面积为70‑80kg/m3；本发明以玻化废弃砖瓦骨料和蛭石骨料为砂浆骨料，采用硅酸盐水泥或者铝酸盐水泥为胶凝材料，可以对废弃砖瓦实现资源化利用，最大限度的减轻由废弃砖瓦造成的环境污染、资源能源的消耗等问题；本发明将废弃砖瓦进行破碎加工，制备成废弃砖瓦微粒，通过盐酸酸化，增大废弃砖瓦微粒比表面积和孔隙度，从而降低废弃砖瓦微粒的导热性，有效提高砂浆的防火性能。
