Effect of fillers Granulated slag on the durability of HPC in marine environment

Abstract

The combined effect of fillers of silica fume and blast furnace slag on the durability of high performance concretes was studied .The storage media are: seawater and tap water as reference. This work focuses on the effect of the incorporation of different amounts of milk more silica fume on the mechanical strength of concretes with limestone cements and its influence on sustainability with respect to marine. The results show that the addition of quantity 10%slag and 5% silica fume offers the best protection in marine waters .One of the indicators of sustainability are selected and monitored from 1 day to 28 days are variations of unconfined compressive strengths . The PH of the solution, especially related to the frequency of renewal baths, appears as an important parameter of aggressiveness.
