Prefabricated composite floor slab and preparation method thereof
The invention discloses a prefabricated composite floor slab and a preparation method thereof. The concrete comprises the following raw materials in parts by weight: 2-8 parts of cement, 8-14 parts of steel slag, 1-3 parts of a mineral admixture, 25-35 parts of fine aggregate, 40-50 parts of coarse aggregate, 0.1-0.5 part of a water reducing agent and water. The steel slag is used as a carbonization material, on one hand, the steel slag has high carbonization performance, carbonization reaction can be carried out, early strength can be provided, the maintenance period can be shortened, and the problem of volume stability of the steel slag can be effectively solved after carbonization; on the other hand, internal unreacted steel slag and cement can be hydrated in the later period, the strength is further improved, the internal structure of the prefabricated composite floor slab is more compact, and the durability is improved. The formula provided by the invention has the characteristics of large steel slag doping amount and excellent carbonization performance. In addition, large-scale application of the steel slag in prefabricated component building materials can be achieved, CO2 is effectively absorbed, and storage and utilization of CO2 are achieved.
本发明公开一种预制叠合楼板及其制备方法。按重量份计，其原料包括：水泥 2‑8份、钢渣 8‑14份、矿物掺合料 1‑3份、细骨料 25‑35份、粗骨料 40‑50份、减水剂 0.1‑0.5份和水。本发明以钢渣作为碳化材料，一方面钢渣具有较高的碳化性能，可以进行碳化反应，提供早期强度，缩短养护工期，碳化后也可以有效解决钢渣体积稳定性的问题；另一方面内部未反应钢渣与水泥也可以在后期进行水化，进一步提升强度，使预制叠合楼板内部结构更加密实，提高耐久性。本发明的配方具有钢渣掺量大、碳化性能优异的特点。此外，还可以实现钢渣在预制构件建筑材料中的大规模应用，并且有效吸收CO2，实现CO2的封存和利用。
