The Effect of Admixtures on Anti-Permeability of C30 Anchor Anti-Seepage Mass Concrete

Abstract:

Abstract. It was based on bridge anchor structure of three gorges reservoir area, from the perspective of enhancing the anti-permeability performance of mass concrete, taking into account the economic perspective, with the use of large dosage of fly ash and slag powder to replace cement to reduce the water-binder ratio and hydration heat, improve the anti-permeability performance of concrete, according to the characteristics of mass concrete. Through the test, the influence law of admixtures on impermeability of C30 mass concrete were obtained, and at the same time the better mix proportion of C30 anti-seepage mass concrete used in bridge anchor structure was recommended.
