Reinforced recycled red brick aggregate, preparation method thereof, mortar and preparation method thereof
The invention discloses a reinforced recycled red brick aggregate and a preparation method thereof, and mortar and a preparation method thereof, and relates to the technical field of building materials, and the method comprises the following steps: calcining the recycled red brick aggregate at 400-600 DEG C, after calcining, carrying out ball milling, sieving, and separating to obtain a first recycled coarse aggregate and a first recycled fine aggregate; soaking the first recycled coarse aggregate in a weak acid solution for 8-10 hours, taking out the first recycled coarse aggregate, sieving the first recycled coarse aggregate, and separating the first recycled coarse aggregate into a second recycled coarse aggregate and a second recycled fine aggregate; soaking the second recycled fine aggregate in a polyethyleneimine solution for 4-6 hours to obtain third recycled fine aggregate and soaking waste liquid; performing precipitation treatment on the soaking waste liquid to obtain supernatant liquid and precipitate, and separating the precipitate to obtain fourth regenerated fine aggregate; and drying the first recycled fine aggregate, the third recycled fine aggregate and the fourth recycled fine aggregate in the air, and sieving to obtain the reinforced recycled red brick aggregate with the particle size of 0.15-4.75 mm. The strength of the recycled red brick aggregate can be improved.
本申请公开了强化再生红砖骨料及其制备方法、砂浆及其制备方法，涉及建筑材料技术领域，方法包括：再生红砖骨料置于400℃‑600℃温度下煅烧，煅烧后进行球磨、过筛，分离为第一再生粗骨料和第一再生细骨料；弱酸液浸泡第一再生粗骨料8‑10h，取出后过筛，将第一再生粗骨料分离为第二再生粗骨料和第二再生细骨料；第二再生细骨料放入聚乙烯亚胺溶液浸泡4‑6h，得到第三再生细骨料和浸泡废液；浸泡废液进行沉淀处理，得到上层清液和沉淀物，分离出沉淀物，得到第四再生细骨料；将第一再生细骨料、第三再生细骨料和第四再生细骨料晾干后过筛，得到粒径在0.15‑4.75mm的强化再生红砖骨料。本申请能够提高再生红砖骨料强度。
