Lightweight recycled concrete and preparation method thereof
The invention discloses light recycled concrete and a preparation method thereof, and the preparation method of the light recycled concrete comprises the following steps: step (1): uniformly mixing recycled aggregate, fly ash, ceramsite and recycled stone powder to obtain a first mixture; (2) uniformly mixing cement, water, a water reducing agent and sand to obtain a second mixture; and (3) adding the first mixture into the second mixture, and uniformly mixing to obtain the recycled concrete. According to the light recycled concrete and the preparation method thereof, the concrete can be light in weight, convenient to prepare, good in heat insulation and compression resistance effects, short in setting time and good in early strength, shale ceramsite, construction waste, ceramsite and recycled aggregate are used as raw materials, and the light recycled concrete is environment-friendly and energy-saving. While resource recycling can be effectively achieved, the heat preservation effect of the concrete is improved, and energy conservation, emission reduction and environment protection are better facilitated.
本发明公开了一种轻质再生混凝土及其制备方法，所述轻质再生混凝土的制备方法包括以下步骤：步骤(一)：将再生骨料、粉煤灰、陶粒和再生石粉混合均匀，得到第一混合物；步骤(二)：将水泥、水、减水剂和沙子混合均匀，得到第二混合物；步骤(三)：将第一混合物加入第二混合物，混合均匀，得到再生混凝土。该轻质再生混凝土及其制备方法，能够使混凝土的质量较轻，且制备方便，具有良好的隔热抗压效果，能够使混凝土具有较短的凝结时间并保证良好的早期强度，并且利用页岩陶粒、建筑垃圾、陶粒和再生骨料作为原料，在能够有效实现资源循环利用的同时，还提升了混凝土的保温效果，更有利于节能减排和保护环境。
