Ceramic sand-based light ultra-high performance concrete and preparation method thereof
The invention relates to pottery sand light ultra-high performance concrete and a preparation method thereof, aims to solve the problems of large density and large shrinkage of traditional ultra-high performance concrete, and prepares the light ultra-high performance concrete with apparent density of 2000kg/m or less and strength of 110MPa or more by adopting pottery sand as a light aggregate and optimizing grain composition of the pottery sand and a cementing material. According to the technical scheme, the preparation method comprises the following steps: selecting cement, fly ash, silica fume and multi-particle-size pottery sand in a specific proportion, determining an optimal mixing proportion through Andriasen and a compressible stacking model, and adding copper-plated steel fibers to improve mechanical properties; the material cost, self weight and shrinkage rate are effectively reduced, and the prepared concrete has good fluidity and volume stability, is environment-friendly and energy-saving, improves the construction efficiency and structural durability, has wide building application prospects, is especially suitable for the engineering field sensitive to self weight and requiring high strength, and has wide application prospects. And a new path is provided for promoting light-weight and high-performance development of building materials.
一种陶砂轻质超高性能混凝土及其制备方法，旨在解决传统超高性能混凝土密度大、收缩大的问题，通过采用陶砂作为轻质集料，并优化陶砂与胶凝材料的颗粒级配，配置出表观密度在2000kg/m³以下，强度达110MPa以上的轻质超高性能混凝土；技术方案包括选用特定比例的水泥、粉煤灰、硅灰及多粒径陶砂，通过Andreasen和可压缩堆积模型确定最佳混掺比例，并加入镀铜钢纤维以提高力学性能；有效降低了材料成本、自重及收缩率，制备出的混凝土具有良好流动性和体积稳定性，环保节能，提升了施工效率与结构耐久性，建筑应用前景广泛，尤其适用对自重敏感且要求高强度的工程领域，为推动建筑材料轻量化、高性能化发展提供了新路径。
