Concrete mixtures containing slag cement should be proportioned using conventional design. Slag cement should be substituted for Portland cement on a one-to-one basis by mass. Specific gravity of slag cement ranges from 2.85 to2.94, depending upon the slag cement source-as compared to 3.15for Portland cement.
Maximum strength, low risk of cracking, improved workability, and superior finish are the advantages of PSC.
PPC cement is finer than ordinary Portland cement and due to pozzolanic action; it improves the pore size distribution and also reduces the micro-cracks at the transition zone. Portland cement comes in three major categories- Ordinary Portland Cement, Portland Slag Cement, Portland Pozzolana Cement.
Portland Slag Cement, commonly known as PSC, is blended cement. Slag is, essentially, a non-metallic product comprising of more than 90% glass with silicates and alumino-silicates of lime. At JSW Cement, we use superior quality slag produced at our steel manufacturing plant, conforming to IS: 12089 standards for producing PSC.
The main advantage is that the amount of energy needed to produce a kilo gram of slag cement is much less than for ordinary Portland cement because the slag is essentially a waste material which can be used beneficially in making cement. So, slag cement is environmentally friendly. There are very few major advantages or disadvanta
A normal portland cement (PC) and a blast-furnace slag cement (BFSC) in compliance with the requirements of German standard DIN 1164 were selected for the investigations. Four bituminous coal fly ashes (FA) with different heavy metal contents were chosen as concrete addition.
PSC Portland slag cement is a blended cement. As per IS 45-2015, PSC can be produced by Adding 25-70% of slag with clinker and gypsum. PSC is Produced using superior quality slag produced from the steel plant which confirm to IS: 12089. Slag is a high glass, non-metallic Product Containing Silicate and Alumino-Silicates of lime.
General use of the Portland cement, Siliceous (ASTM C618 Class F) Fly Ash, Calcareous (ASTM C618 Class C) Fly Ash, slag cement, and silica fume in concrete is as primary binder, cement replacement, cement replacement, cement replacement, and property enhancer, respectively . 2. Types of Cements and Their Composition and Uses
Portland Slag Cement, commonly known as PSC, is blended cement. Slag is, essentially, a non-metallic product comprising of more than 90% glass with silicates and alumino - silicates of lime. At JSW Cement, we use superior quality slag produced at our steel manufacturing plant. It is created with a combination of upto 45- 50% slag, 45% – 50% ...
Portland slag cement is the most suitable cement for concrete paths, mass concrete uses, structures and bases, Pre-cast concrete, concrete open to seawater and oceanic use. All compositions produce high ultimate strength, but as slag content is increased, initial strength is reduced, while sulfate resistance upsurges and heat evolution moderates.

Aug 12, 2014· The Advantages of Portland-Limestone Cement Portland-limestone cement has a smaller carbon footprint with no drawbacks. The concrete industry has been getting beat up for the past decade over the large carbon footprint of cement, and it's true that cement manufacturing releases a significant amount of carbon dioxide into the environment.
Granulated Blast Furnace Slag is a non-metallic by-product produced during the process of Iron making. It primarily consists of silicates, alumino-silicates, and calcium-alumina-silicates. Due to strict process & quality control from generation to dispatch ensure IS 12089, 1987 is far exceeded.
Slag cement is commonly found in ready-mixed concrete, precast concrete, masonry, soil cement and high temperature resistant building products. While there are many applications and benefits of slag cement, a few are highlighted below and detailed information sheets are located here.
Advantages of Portland Slag Cement The advantages of portland slag cement over ordinary Portland cement are as follows: PSC has good compressive strength comparable to OPC in long-term and hence is less permeable and more durable as compared to OPC. PSC is smooth powered cement, which is nearly white in colour.
Maha – Portland Slag Cement (PSC), conforming to the IS 455-1989, is manufactured from high quality clinker and superior quality granulated blast furnace slag.The slag used contains more than 95% glass content – the most desired parameter to manufacture PSC. The unique feature of our Grinding Units used for manufacturing this cement is the Vertical Roller Mills (VRM) – the most modern ...
It works synergistically with Portland cement to increase strength, reduce permeability, improve resistance to chemical attack and inhibit rebar corrosion. Slag cement is used in virtually all concrete applications A high strength cement forming a Durable concrete with Highest 1 day strength of around 18 Mpa. Advantages of using Star Slag Cement:-
Advantages and Use 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. Generally, the use of high-grade cement offers many advantages for ...
Portland Pozzolana cement is integrated cement which is formed by synthesising OPC cement with pozzolanic materials in a certain proportion. It is commonly known as PPC cement. In this article we discuss about the properties, manufacture, characteristics, advantages and disadvantages of Portland Pozzolana cement. Contents:What is pozzolana or pozzolanic material?Types of pozzolana materials :1.
Penden Special Cement is the brand name of Portland Slag Cement (PSC) manufactured at Penden cement as per IS:455-2015, using 45-56% in-house produced high quality Portland clinker world's purest mineral 3-5% gypsum sourced from Pemagatshel in Bhutan and Granulated Blast furnace 40-45% Slag.
Ordinary Portland Cement: – OPC is produced by finely grinding OPC clinker obtained from the cement kilns. This cement on hydration produces C-S-H gel (Calcium – Silicate – Hydrate) Gel, which provides cementation property and is the primarily responsible for strength is cement products. Along with C-S-H gel it also produces Ca(OH)2, which does not provide any strength, rather it causes ...
Slags are used as a replacement of portland cement in amounts typically between 25 and 70% of the total mass of cementitious material. Slag concretes have improved long-term strengths even though their early strength development is lower than portland cement concretes.
Blast furnace slag cement is the mixture of ordinary Portland cement and fine granulated blast furnace slag obtained as a by product in the manufacture of steel with percent under 70% to that of cement. Ground granulated blast furnace slag cement (GGBFS) is a fine glassy granules which contain cementatious properties.
Replacement. GGBFS can be used as a portland cement replacement ranging from 35%-70% by mass. Advantages. When used in portland cement, GGBFS offers the following advantages over unmodified portland cement:
