EXPLORAX Division of Geocon Products offers broad range of Silica Products that contains crystalline and amorphous silica particles. In Oilefield Cementing applications Silica mainly used as densification, pozzolan and reactivity product to attain high & early strength of concrete design. ULTRABLOCK MK series Silica are Micronized Amorphous Silica Grey color in powdered form used to counteract and control strength retrogression.

The Strength retrogression in concrete terminology mean during the hydration products that are formed when cement is exposed to high temperatures (>110°C / 230°F). Due to this there is decline of cement strength at elevated temperatures & therefore decreased in strength & pore diameter is observed.

The strength retrogression is achieved by reacting Silica with Calcium Hydroxide turn into Calcium Silicate bond this reduce permeability zonal isolation in concrete pore.
