Benefits of A-chem micro silica in concrete aditive longer service life: A-Chem microfine is a highly reactive pozzolan and give concrete a dense microstructure, lower permeability & higher electrical resistivity leading to improved durability.
The durability of a reinforced concrete structure can be difined as the capability of the structure to maintain its original functional and structural characteristics during the expected service life in the exposure conditions it was intended for combined with correct design and workmanship, micro silica concrete offer characteristics that will ensure long term durability and service life. Higher strength concrete that is often essential in magor projects such as record breaking tall building, roads and bridge.
These engineering applications requiring high strength concrete use microsilica as a cost effective means to increase comprehensive strength. Ultra High strength concrete (UHSC) typically defined as > 150mpa can be achieved using higher dosage of A- Chem microfine increased strength results from micro silica``s particles packing & pozzolanic reaction in micro silica concrete the thickness of the transition zone (interface) between the cementitious paste and aggregate is reduced and the CH crystal are smaller and more randomly oriented, resulting in decreased porsoity & increased inter face bonding strength.
