液态渣混凝土的预估强度回归方程和长期强度

Regression Equation for predicting Strength of Concrete with Liquid Slag Fines and its long term Strength

通过大量的液态渣混凝土(液态渣作细骨料)和天然砂混凝土的配制试验,考查了水泥强度、水灰比、细骨料品种等因素对混凝土拌合物的和易性及混凝土强度等性能的影响,对试验结果进行统计分析,得出了符合本试验条件下的液态渣混凝土的预估强度回归方程。并对液态渣混凝土的长期强度进行了测定。

Through numerous mix tests for concrete with liquid slag fines and natural sand,a study is carried out for influence of cement strength,water/cement ratio and type of fine aggregate on workability of fresh concrete and strength of the concrete.After statistical analysis of experimental data,a regression equation for predicting strength of concrete with liquid slag fines is obtained.In addition,long term strength of liquid slag concrete is determined.
