Admixture to reduce alkali-silica reactivity in concrete
BATIMIX Alkali-Silica 650 is a lithium nitrate admixture used to minimize the alkali-silica reactivity (ASR) that may occur in the concrete.
ASR is a chemical reaction. It occurs between the reactive silica in aggregates used to make concrete and the alkalis, sodium or potassium, present in the concrete. The reaction causes the formation of a gel that absorbs water and swells, exerting internal pressure that can lead to cracking and premature deterioration of the concrete.
BATIMIX Alkali-Silica 650 provides maximum protection against ASR. It can be used for plain or reinforced concrete, precast, prestressed, and architectural.
Concrete prepared with BATIMIX Alkali-Silica 650 is characterized by the following:
In the plastic state:
In the hardened state:
0.8% to 2.5% of the cement weight
BATIMIX Alkali-Silica 650 is not considered a hazardous product. However, it should not be swallowed or allowed to come into contact with skin and eyes. Suitable gloves and goggles should be worn.
