混凝土掺合料优化组合方法的研究

Research on the Optimization of Combination Method of Concrete Mineral Admixture

根据混凝土掺合料的酸碱性、活性和吸水性等物理化学性能,提出划分混凝土掺合料种类的不同方法。并根据掺合料性能对混凝土工作性、强度和耐久性的影响,提出改善混凝土性能的掺合料优化组合方法。此外,探讨了掺合料优化组合提高混凝土工作性、强度和耐久性的作用机理。

According to the properties of mineral admixture of concrete, such as acid-alkaliness, reactivity and water-absorbability, the classification methods of it were presented. And based on analysing the influences of this propenties on concrete workability, strength and durability, the methods and rules for optimizing the combinations of different admixture have been put porward. Besides, the mechanism of that the optimized combination will improve the workbility, strength and durability of concrete has been discussed.
