Portland Slag Cement(PSC) As per the great success achieved by Jagdamba Cement Industries Pvt. Difference Between OPC and PPC Cement . cement concrete is about 6 times higher than the slag cement concretes. Portland vs. Slag cement concrete WCPA Annual Concrete Pavement Workshop Bruce Blair Presentation February 12, 2015 22 of 41. 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. GGBS can be used as a partial replacement of OPC cement in concrete production at batching plants. There is three types of cement available in market or ordinary Portland cement (OPC) Portland slag cement (PSC) and portland pozzolana cement (PPC). A multi-method approach was used for the investigation and comparison of alkali-activated slag binders (AAS), pure slag and ordinary Portland cement (OPC). A metered proportion of crushed, dried limestone is fed to the finish grinding mill, along with clinker and gypsum. OPC (Ordinary Portland Cement) is the basic form of cement with 95% cement clinkers and 5% being gypsum. Multifold Advantages . Slag is, essentially, a non-metallic product comprising of more than 90% glass with silicates and alumino-silicates of lime. 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? Conflicting data exists, however, as to if and when the strength of slag cement eventually “catches up” to similar concrete containing 100% OPC. Table 1 illustrates the major chemical compositions of OPC and CAC. Which Cement is Better PSC or PPC ?What is(Portland slag Cement ) & (Portland pozzolona Cement)? Blended cements are now being considered superior as compared to conventional OPC category of cements. HSBFC is designed to ensure … In this article we discuss about characteristics, types, advantages and uses […] Visit Materialtree.com for full details of OPC 53 Grade Cement Vs OPC 43 Grade Cement Vs PPC Vs PSC, like IS Standard, Full Name, Sizes Available, Compression Strength. Since OPC 53 grade requires less time to gain early strength, we recommend it for RCC/structural members. It provide higher strength to rcc roof slab withstand with different types of load acting on it. It is preferred in places where there is need of fast construction. Gypsum is as an additive to increase the setting time of the cement to a workable 30 minutes or more.. OPC Cement gives high compressive strength at early ages and at 28 days. Slag cement is a latent hydraulic material, meaning that with use of this material, the rate of strength gain will be lower when compared to OPC concrete. This cement is the standard norm being manufactured and sold by cement manufacturers around the world. Construction materials in our world have come a long way.
