IRAN BITUMEN GRADE 60/70
Bitumen penetration grade 60/70 is semi-hard penetration grade bitumen using as paving grade bitumen suitable for road construction and repair also for the production of asphalt pavements with the below technical specification. This grade of bitumen is mainly used in the manufacture of hot mix asphalt for bases and wearing courses.Bitumen 60/70 is most used bitumen grade and basic material for all other bituminous products.
Gypsum powder or plaster is a building material that features similar properties to mortar or cement. The powder is created by heating gypsum a soft naturally occurring mineral to roughly 300 degrees Fahrenheit (150 °C) and then mixing with water. The resulting paste hardens as it cools, developing a relatively soft, pliable finished product. Unlike mortar or cement, which dry much harder. It can be sanded or otherwise manipulated once cured, making a valid option for aesthetic, non-load bearing purposes.
Blast Furnace Slag is a by-product of the manufacturing of steel in a blast furnace. Initially, in its molten form, it is diverted to a granulator where it is quenched with water and rapidly cooled to form glassy, non-metallic granules which are silicates and aluminosilicates of calcium. These granules are dried to produce Granulated Blast Furnace Slag (GBFS) and then ground to a suitable fineness to produce Ground Granulated Blast Furnace Slag (GGBFS). When used as a cementitious material in concrete, GGBFS enhances long-term performance and durability characteristics while reducing life-cycle and maintenance costs.
