"We believed in working together, there is no place where we are not."
MARKCHEM SCA is composed of silicon dioxide (SiO2), collected from silica ores that is crushed to make a fine powder, silica alloys, natural volcanic ash and ferro silica. SCA will react with the Calcium Hydroxide from the cement, which will form more of the Calcium Silicate hydrate, increasing the strength of the concrete. Using SCA will also increase the durability of the concrete and compressive strength. SCA also help in waterproofing and bleeding prevention in concrete
