advantages of slag cement

Double Bull Portland Slag Cement (PSC) is specially designed and manufactured by intergrinding clinker with superior quality ground granulated blast furnace slag for even particle distribution to produce specialised cement, resistant to chemical ingress. PSC has the lower evolution of heat. It is created with a combination of upto 45- 50% Using slag cement to replace a portion of Portland cement in a concrete mixture is an efficient way to make concrete more consistent. Vertical roller mill is a special equipment which focuses on slag solid waste industry. Among all the construction materials used in the world, concrete is most widely used due to its unique advantages compared to other materials. The studies show that the GGBFS can be replaced from 30 to 85 % of the cement weight. ADVANTAGE. It is observed that the composition of 7.5% RHA + 22.5% GGBS+ 60% of quarry sand gives good strength results. 10 major advantages of concrete are explained below. Slag Cement, has been incorporated into concrete projects for over a century to improve durability and reduce life cycle costs.Among its measurable benefits in concrete are better workability and finish ability, higher compressive aggressive chemicals. It improves durability & resilience. Eco-friendly; Made of recycled materials; Less Carbon monoxide emission; 16. Ground granulated blast furnace slag cement (GGBFS) is a fine glassy granules which contain cementatious properties. The slag contains oxides of lime, alumina, and silica and easily replaces clay or shale used in the manufacture of ordinary Portland cement. It has been possible to upgrade the qualities of cement by using high-quality limestone, modern equipment, closer on line control of constituents, maintaining better particle size distribution, finer grinding and better packing. Blended cement is obtained by mixing OPC with mineral admixtures or additives like fly ash, slag or silica fumes. It is actually a byproduct of iron production. Slag cements disappeared from the market mainly because they presented relatively low mechanical resistance at first aging and failed to present other competitive advantages concerning cement other than lowering the price. • Slag can also provide improved resistance to chlorides, sulfates, and ASR when used at replacement levels of 35 to 50%. Portland slag cement is the most suitable cement for concrete paths, mass concrete uses, structures and bases, pre-cast concrete, concrete open to sea water and oceanic use. The molten slag at a temperature of about 1500°C 13.3.2.2 Slag cement use for special applications. The normal ratio of the mixture remains the same. The combination of limestone and slag with Portland cement can help to produce a new cement-based material which has advantage over binary blended cement. The Multi-fold Advantages of GGBS. At JSW Cement, we use superior quality slag produced at our steel manufacturing plant, conforming to IS: 12089 standards for producing PSC. Description: Concrete is one of the most widely used building materials throughout the world, and as such, it is in everyone’s best interest to consider more sustainable options.
