HSBFC is designed to ensure … Various grades of portland blast furnace slag cement (PBFC) and normal portland cement (OPC) concrete have been cured under adiabatic and semi-temperature matched curing conditions. ABSTRACT: Ordinary Portland cement (OPC) has been traditionally used in the construction of concrete silos in Ireland. ratio of BFS/OPC = 30/70 was a basic testing material, and the OPC was used as a control. OPC (Ordinary Portland Cement) is the basic form of cement with 95% of it being the clinker and 5% being gypsum which is added as an additive to enhance the setting time of the cement to a workable 30 minutes odd or so. With same cement content, concrete with OPC 53 grade will have more strength as compared to concrete with OPC 33 grade. The slag cement with a wt. High Slag Blastfurnace Cement (HSBFC), our high performance specialty cement, is a homogeneous blend of Ordinary Portland cement (OPC) and Ground Granulated Blastfurnace Slag (GGBS/GGBFS) complying with SS EN 197-4, BS 4246, SS 476, DIN 1164, JIS R5211, and ASTM C595. The Multi-fold Advantages of GGBS. Blended cement can improve workability, strength, durability and chemical resistance of concrete. on exposure to silage effluent. Blended cements are now being considered superior as compared to conventional OPC category of cements. Hence, during production, the amount of carbon dioxide released in the atmosphere will be reduced. One-part alkali-activated fly ash/slag binders have been promoted as an environmentally friendlier alternative to Ordinary Portland Cement (OPC). Paste Studies The cement pastes were produced by mixing cement, slag, water, and different kind of additives. There is three types of cement available in market or ordinary Portland cement (OPC) Portland slag cement (PSC) and portland pozzolana cement (PPC). Both are eco-friendly materials but Slag Cement uses natural and industrial waste thus reducing the environmental pollution. GROUND GRANULATED BLAST FURNACE SLAG. max. The granulated slag is further processed by drying and then grinding in a vertical roller mill or rotating ball mill or roller press to a very fine powder,which is called GGBS. Portland Slag Cement(PSC) As per the great success achieved by Jagdamba Cement Industries Pvt. Slag Cement. There is no need to follow the trend blindly. This cement is the standard norm being manufactured and sold by cement manufacturers around the world. Slag cements are resistant to sea water only with an addition of >60% slag if the OPC is a non-marine cement.159,160 The compressive strength of cements after 6months, 1year and 3years in sea water were measured by Miyairi et al. In this article we discuss about characteristics, types, advantages and uses […] It is preferred in places where there is need of fast construction. When slag cement hydrates, it reacts with sodium and potassium alkali and calcium hydroxide [Ca(OH)₂] to produce additional C-S-H. Why OPC and GGBS combination is Preferred?

Similar results are obtained also for the C30 and C35 concrete classes. Much of this is thanks to the development of technology, particularly in the production of concrete which is based on cement. 2. It is a recovered industrial by-product of an iron blast furnace. As seen in the Figure 1, for the pure portland cement concrete substantial reduction in the chloride permeability was obtained between the C35 and C40 . The portland slag cement has many advantages over ordinary portland cement (OPC). Magnesium (MgO) is present in small quantities as an impurity associated with limestone. Blended cement is obtained by mixing OPC with mineral admixtures or additives like fly ash, slag or silica fumes. different from OPC. CAC contains a far greater amount of alumina and a far less amount of silica. Comparisons of the compressive strength between adiabatic, semi-temperature matched and ambient cured concrete have been made. OPC is the general purpose cement used in concrete constructions. PPC (Portland Pozzolana Cement) is a variant of OPC (Ordinary Portland Cement.) Conflicting data exists, however, as to if and when the strength of slag cement eventually “catches up” to similar concrete containing 100% OPC. How is it made, and what’s different about it? Multifold Advantages . Comparison of GGBS vs FLY ASH. #PSCvsPPCcement #Portlandslagcement #Portlandpozzolnacement The Portland slag cement is one such cement, which uses blast furnace slag in the production of cement.
