Concrete applied to large-volume radiation-proof building and construction process thereof
The invention relates to concrete applied to a large-size radiation-proof building and a construction process of the concrete. The concrete grout applied to the large-volume radiation-proof building comprises the following components: cement, sands, sandstones, barite, polymerized alcohol amine, polyhydroxy polyester, epoxy resin, and water; the construction process of the concrete applied to thelarge-volume radiation-proof building further comprises the following steps: 1), hardening a site; 2), mounting a formwork system; 3), binding reinforcing steel bars; 4), pouring concrete grout of thehorizontal structure; 5), controlling the layered pouring thickness of the concrete grout; 6), carrying out temperature control maintenance on mass concrete of all ages; 7), removing formwork framesand scaffolds in the formwork system; and 8), sealing lead plates at construction joints. According to the invention, the adiabatic temperature rise of the mass concrete can be effectively reduced, hydration heat can be reduced, the temperature difference between the inside and the outside of the concrete can be controlled, the radiation shielding performance and the crack resistance of the concrete can be improved, and the radiation protection performance effect of the structure can be achieved.
本申请涉及一种应用于大体积防辐射建筑的混凝土及其施工工艺。应用于大体积防辐射建筑的混凝土浆液包括以下组分：水泥；砂；砂石；重晶石；聚合醇胺；多羟基聚酯；环氧树脂；水；应用于大体积防辐射建筑的混凝土的施工工艺还包括以下步骤：步骤1），场地硬化；步骤2），模架体系安装；步骤3），钢筋绑扎；步骤4），水平结构的混凝土浆液浇筑；步骤5），混凝土浆液分层浇筑厚度控制；步骤6），各龄期大体积砼温控养护；步骤7），模架体系中模板架、脚手架拆除；步骤8），施工缝处铅板密封。本发明能有效降低大体积混凝土的绝热温升，减小水化热，控制混凝土内外温差，提高其辐射屏蔽性能及抗裂性能，达到结构的防辐射性能效果。
