Lightweight construction waste reclaimed sand and production method thereof
The invention relates to the technical field of building materials, and particularly discloses light building waste reclaimed sand and a production method thereof. The light construction waste reclaimed sand comprises the following raw materials, 10 to 30 parts of aerated brick powder; 20-40 parts of red brick powder; 12 to 20 parts of fly ash; 2 to 6 parts of tetraethoxysilane; 5-9 parts of alkaline phenolic resin; and 7-11 parts of water. The production method comprises the following steps: S1, drying and grinding the aerated brick and the red brick into powder, adding the fly ash, and uniformly stirring to obtain a mixture; s2, adding tetraethoxysilane and water into the mixture in the step S1, uniformly stirring, then adding alkaline phenolic resin, fluorine-containing alkyl alkoxy silane and slaked lime, and continuously uniformly stirring to obtain slurry; s3, drying the slurry prepared in the step S2 to prepare dry particles; and S4, the dried particles prepared in the step S3 are cured, and the reclaimed sand is obtained. The method has the advantage of enhancing the strength of the reclaimed sand.
本申请涉及建筑材料技术领域，具体公开了一种轻质建筑垃圾再生砂及其生产方法。轻质建筑垃圾再生砂的原料包括；加气砖粉10‑30份；红砖粉20‑40份；粉煤灰12‑20份；正硅酸乙酯2‑6份；碱性酚醛树脂5‑9份；水7‑11份。其生产方法为：S1：将加气砖、红砖烘干磨细成粉，加入粉煤灰搅拌均匀得到混合物；S2：在步骤S1的混合物中加入正硅酸定酯和水，搅拌均匀，然后加入碱性酚醛树脂、含氟烷基烷氧基硅烷、消石灰继续搅拌均匀得到浆体；S3：将步骤S2制得的浆体干燥制得干燥颗粒；S4：将步骤S3制得的干燥颗粒进行养护，得到再生砂。其具有增强再生砂强度的优点。
