Abstract

To address the drawbacks of high energy consumption and insufficient durability in traditional concrete, and to promote the greening and high-performance development of concrete, this study focuses on the application performance and durability of new industrial solid waste admixtures in concrete. Through single-factor variable experiments, the influence of different admixture dosages on the workability and mechanical properties of concrete was explored. Various testing methods were used to evaluate its impermeability, freeze-thaw resistance, chemical erosion resistance, and carbonation resistance, and the mechanism of action was analyzed using microscopic testing. The results show that, at appropriate dosages (15%–25%), the new admixtures can significantly optimize the workability and mechanical properties of concrete and improve durability indicators. A durability evaluation system based on multi-dimensional indicators was established, providing theoretical support and technical basis for the engineering application of the new admixtures.
