Powder silica fume (undensified) for high performance concrete
BATIMIX Silica Fume 710 is a powder silica fume mineral additive. It is used to produce high-performance concrete. It is available in two forms: BATIMIX Silica Fume 710 U, in an un-densified form with bulk density typically of 200 to 350 kg/m³, and BATIMIX Silica Fume 710 D, in a densified form with a bulk density of typically 450 to 700 kg/m³.
When added to a concrete mix, the ultra-fine particles of BATIMIX Silica Fume 710 U significantly improve the particle packing, as they physically fill the voids in the cement paste. This leads to a more densified concrete skeleton, with reduced levels of bleeding. On the other hand, this product reacts chemically with the calcium hydroxide present in the cement paste, yielding a calcium silicate hydrate gel that significantly enhances strength, water/chloride impermeability, and durability.
BATIMIX Silica Fume 710 U is incorporated in a wide variety of high strength and specialty concrete mixtures. It is used to produce underwater, shotcrete, self-consolidating, and pre-stressed concrete. It is also used to improve the strength and reduce the sizing of structural sections of columns, retaining walls, bridges, dams, marine structures, and various structural elements.
Concrete prepared with BATIMIX Silica Fume 710 is characterized by the following:
In the plastic state:
In the hardened state:
BATIMIX Silica Fume 710 is not a hazardous material. However, it should not be breathed or allowed to come into contact with skin and eyes. Suitable gloves and goggles should be worn. For additional information, kindly refer to the product’s Material Safety Data Sheet.Reference:MK-PR-5547
