Silica Fume is a by-product of producing silicon metal or ferrosilicon alloys. Silica Fume consists primarily of amorphous (non-crystalline) silicon dioxide (SiO2). Our Silica Fume product range is GMS85, GMS90 and GMS94
Fly ash is a by-product of power plants fuelled by coal. Fly ash is a pozzolan that when mixed with lime, combines to form cementitious compounds. Concrete containing fly ash becomes stronger, more durable and more resistant to chemical attack. Our Fly Ash product range is GMF75 and GMF80
Lytag products are secondary aggregates made from Pulverised Fuel Ash (PFA), a by-product from coal fired power stations which makes them truly sustainable. General Properties Lytag is very light having a bulk density of between 700 and 800 kg/m3. This is half the weight of normal aggregate. Void ratio exceeds 40% Resistant to high temperatures Spherical granular particles Resistant to freeze/thaw cycles
GMX 100 is intended for use in factories and laboratories and is suitable for mixing all types of materials in wet and dry state.
