Low Frequency Ballast

Aggregates are mixtures of sand, gravel, crushed rock or other bulk minerals used in construction, principally as a component of concrete, and in civil engineering. At CEMENTATION we supply aggregates for a range of core applications, from fill materials to aggregates that can be used in concrete, precast concrete, asphalt and for surface dressing. Aggregate plays an important role in concrete and construction part. We supply quality material which makes durable concrete with higher compressive strength and low permeability having better finish. We can supply a wide range of coarse, fine and blended aggregates in accordance with international standards. We acquire rock mines and stone crushing plants and enable us to fulfil contract of any size. Progressive stages if crushing and screening enable us to produce a range of aggregate sizes (06mm to 65mm) APPLICATIONS Road and Highway surfaces Constructions or Civil work Railway Ballast To make Concrete or Asphalt Filling

Ramming mass is commonly used in metallurgy, building materials, non-ferrous metal smelting, chemical, machinery and other manufacturing industries. Ramming mass is widely used in non-core intermediate frequency furnace and core induction furnace. As an intermediate frequency furnace ramming material, refractory ramming is applied to melt gray cast iron, nodular cast iron, malleable cast iron, vermicular cast iron, and cast alloy steel; to melt carbon steel, alloy steel, high manganese steel, tool steel, heat resistant steel, stainless steel, molten aluminum and its alloys; to melt red copper, brass, white brass, bronze and its alloys, etc. Induction furnaces are used for melting cast iron, mild steel and various alloy steels in foundries and making of steel in mini steel plants using sponge iron The refined high silicon, low iron quartz sand and quartz powder are selected and the fused quartz sand is added as the refractory material., with no slag, no crack, damp proof, convenience of repair, and the corrosion resistance, thus greatly improving the furnace service life span and the economic benefit.. Silica ramming mass can safely be used up to an operating temperature of 1600 deg C. Since it expands very little, it is superior to both alumina and magnesia refractories to resist thermal shocks Acid ramming material is the premixed ramming mass of the lining material. The acid ramming mass is used to smelt a series of metal materials such as ordinary steel and carbon steel. The lining practice best suited to a particular furnace depends upon the capacity and design of the furnace, operation practice adopted during making of a heat, and furnace output.
