摘要
根据C30级混凝土的强度要求,采用均匀设计法制定20组试验方案,对比分析粉煤灰取代率和水胶比对混凝土抗压强度的影响规律。研究发现,随着粉煤灰取代率的增加,混凝土试件抗压强度呈逐渐降低趋势;而随着水胶比减小,其抗压强度随之增加。
By studying the relationship between the change of first grade fly ash replacement rate and water cement ratio of Huaneng Power Plant in Fuzhou, the influence of the 20 experiment groups on the compressive strength of concrete was studied by using uniform design method with the design strength of C30. The research shows that： with the increase of the replacement rate of fly ash, the compressive strength of concrete decreases gradually; while the compressive strength increases with the decrease of water cement ratio.
