Building solid waste regenerated material and preparation method thereof
The invention discloses a building solid waste recycled material and a preparation method thereof, and belongs to the field of building materials, and the building solid waste recycled material comprises reinforced recycled sand powder, natural fine aggregate, water, reinforced recycled micro powder, silicon powder and an aqueous alkali. The obtained building solid waste recycled material is more excellent in compressive strength, alkalinity is reduced after carbonization treatment, the building solid waste recycled material can be used for a fiber-reinforced composite bar concrete structure, a low-alkali service environment is provided for fiber-reinforced composite bars, the etching degree of the fiber-reinforced composite bars in concrete is reduced, and the service life of the fiber-reinforced composite bars is prolonged. Therefore, the durability of the fiber reinforced composite bar concrete structure is improved. And an industrial byproduct silica fume can be effectively utilized, so that the method is economical and environment-friendly, and can be well applied to constructional engineering.
本发明公开了一种建筑固废物再生材料及其制备方法，属于建筑材料领域，所述建筑固废物再生材料包括强化再生砂粉、天然细骨料、水、强化再生微粉、硅粉以及碱水剂。本发明得到建筑固废物再生材料抗压强度更优异，同时碳化处理后碱性降低，可用于纤维增强复合筋混凝土结构，为纤维增强复合筋提供低碱的服役环境，降低纤维增强复合筋在混凝土中的刻蚀程度，从而提高纤维增强复合筋混凝土结构的耐久性。还能有效利用工业副产品—硅灰，经济环保，能很好地应用于建筑工程中。
