摘要:
针对粉煤灰的显著特性及其在工程中的广泛应用,经时工程充分调查、材料成分分析和配合比设计.以水胶比、粉煤灰掺量和砂率为变化参数.采用正交试验法对高掺量粉煤灰混凝土进行试验研究,并对各影响因素进行了深入分析.结果表明.水胶比、粉煤灰取代率是影响混凝土性能的主要因素,砂率对混凝土的流动性和强度影响较大.同时,得出在高掺量粉煤灰状况下各影响因数与混凝土性能的相关关系及其变化规律,可供理论研究和工程实践参考.
Abstract:
Aiming at the remarkable characteristics of fly ash and its wide application in engineering, the time engineering fully investigates, analyzes the material composition and designs the mix ratio. The water-to-adhesive ratio, fly ash content and sand rate were used as the changing parameters. The orthogonal test method was used to conduct experimental research on high content fly ash concrete, and the influencing factors were analyzed in depth. The results show that . The water-to-adhesive ratio and fly ash substitution rate are the main factors affecting the performance of concrete, and the sand rate has a great influence on the fluidity and strength of concrete. At the same time, the correlation between the influencing factors and the concrete properties under the condition of high fly ash content and its variation law are obtained, which can be used as a reference for theoretical research and engineering practice.
