Composite cement carbonized building material product and preparation method thereof
The invention belongs to the technical field of building material products, and particularly relates to a composite cement carbonized building material product and a preparation method thereof. Comprising the following steps: stirring and mixing materials containing composite cement, an admixture, aggregate, a water reducing agent and water to obtain mixed slurry; based on the total mass of the composite cement, the composite cement comprises 80-92% of Portland cement clinker, 3-10% of sulphoaluminate cement clinker and 5-10% of gypsum, pouring the mixed slurry into a mold, and carrying out vibration molding to obtain a test block with a mold; naturally curing the test block with the mold for 2-8 hours, and removing the mold after curing; and performing carbonization maintenance on the test block subjected to form removal to obtain the carbonized building material product. According to the method, the carbonization reaction degree and carbonization effect of the product can be improved, the early strength of the product can be rapidly improved, and the problems of loose structure, temperature difference cracks, shrinkage cracks and the like of a cement concrete interface transition area are remarkably improved and avoided.
本发明属于建材制品技术领域，具体涉及一种复合水泥碳化建材制品及其制备方法。包括以下步骤：将包含复合水泥、掺合料、骨料、减水剂和水的物料搅拌混合，得到混合浆体；以所述复合水泥的总质量计，所述复合水泥包含硅酸盐水泥熟料80‑92％、硫铝酸盐水泥熟料3‑10％和石膏5‑10％；将所述混合浆体浇筑到模具中，经振动成型后，得到带模试块；对带模试块进行自然养护2‑8h，养护后拆模；将拆模后的试块进行碳化养护，即得碳化建材制品。该方法可提高制品碳化反应程度与碳化效果，更快速地提高制品早期强度，显著改善和避免水泥混凝土界面过渡区结构疏松、存在温差裂缝干缩裂缝等问题。
