RESISTANCE OF MORTARS CONTAINING SILICA FUME TO ATTACK BY A SOLUTION CONTAINING CHLORIDES

Mortars prepared at water/cement + silica fume ratios, w/(c+sf), of 0.45 and 0.60 were exposed to a solution containing a mixture of magnesium, calcium and sodium chlorides to investigate their resistance to attack. Mixes contained 0, 10 and 30 per cent silica fume, and sand-binder ratio was 2.25. Stiffness, pore-size distribution, calcium hydroxide content and non-evaporable water were measured before and after exposure to salt solution. Inclusion of silica fume resulted in increased durability of mortar, especially in specimens prepared at w/(c+sf) of 0.45 and cured for 28 days. Specimens prepared at the same w/(c+sf) with 30 per cent silica fume were also durable even after seven days of curing. Calcium hydroxide in mortars was reduced to zero by exposure to the salt solution. (Author/TRRL)
