碱矿渣高钙粉煤灰混凝土的优化及长期性能的研究

STUDY ON OPTIMUM DESIGN AND LONG TERM PERFORMANCE OF CONCRETE OF SLAG-ALKALI FLY ASH

碱矿渣混凝土在自然使用环境中的长期稳定性是该材料耐久性研究中的重要课题 .本研究采用碱矿渣激发高钙粉煤灰的活性 ,配制了碱矿渣高钙粉煤灰混凝土 ,重点测试评价了在北方自然环境中存放 8年后的试件力学性能、显微结构及组成 ,综合分析了该材料的长期稳定性 .

Using the slag_alkali activates the activity of fly ash. By the method of the designs of the mixture ratio and the Quadratic Regression Orthogonal Design, this paper seeks out the best combination and researches several mixture factors having an effect on the rule of the kind of the concrete material properties and long term performance.
