May 01, 2007 The National Council for Cement and Building Materials NCB has done pioneering work in the area of utilisation of industrial by-products for cement manufacture. The joint study aims to utilise the copper slag as raw mix component in the manufacture of Ordinary Portland Cement OPC and as a blending material for Portland Slag Cement PSC ...
Dec 18, 2010 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. The difference in specific gravity means a greater volume of slag cement will be used to replace the same mass of Portland cement.
Cement - Cement - Slag cements The granulated slag made by the rapid chilling of suitable molten slags from blast furnaces forms the basis of another group of constructional cements. A mixture of portland cement and granulated slag, containing up to 65 percent slag, is known in the English-speaking countries as portland blast-furnace slag cement.
Portland slag cement, which is most commonly used in the region, was used for the study complying with IS 455 21.Its specific gravity was 2.87 having initial and final setting times of 70 minutes and 480 minutes, respectively.For fine aggregate, natural sand was used, having a maximum size of 4.75 mm.Its specific gravity was 2.72, conforming to Zone-III, and having a fineness modulus of 2.313.
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.
The two most common types of blended cement using slag cement are Type IS - Portland blast-furnace slag cement in which slag constituent is between 25 percent to 70 percent by mass Type I SM - Slag-modified portland cement in which slag constituent is less than 25 percent Standard Performance Specification for Hydraulic Cement - ASTM C ...
Jun 10, 2019 The main materials selected in this study are magnesium phosphate cement MPC, steel slag and water. The MPC is prepared from a mixture of dead burnt magnesium MgO, metakaolin MK, ammonium dihydrogen phosphate NH 4 H 2 PO 4, borax Na 2 B 4 O 7 10H 2 O and dispersant in various proportions and it can be used directly as ordinary Portland cement. In the case of water
Gujarat Govt made mandatory to use only Portland Slag Cement in coastal Gujarat. Gujarat Government Road amp Building Department has made it mandatory to use only Portland Slag Cement confirming IS 455-1989 in all Buildings, Roads and Bridges and all other constructions in coastal Gujarat and the areas prone to Salinity.
Making Concrete Greener with Slag Cement Slag cement is a byproduct of iron production in a blast furnace. It is a hydraulic cement that can replace between 20 to 80 percent of the portland cement in concrete depending on application, see Table 1 and helps makes concrete even greener. Slag cement contributes the following sustainability ben-
Oct 22, 2013 Nowadays, alkali-activated cements attract worldwide attention because their production is associated with much lower CO2 emissions compared to that of Portland cement PC. However, little information can be found on the strength and durability behavior of concrete made with alkali-activated cement. This is rather surprising since alkali-activated cement has already been used in the past.
Slag is commonly used to make cement. This substance is produced during the smelting process in several ways. Firstly, slag represents undesired impurities in the metals, which float to the top during the smelting process. Secondly, metals start to oxidize as they are smelted, and slag forms a protective crust of oxides on the top of the metal ...
Expanding the use of Portland blast furnace slag cement is one measure included in the plan to achieve the targets of the Kyoto Protocol, and there are large expectations for its ability to help reduce CO 2 emissions. Under the Kyoto Protocol, Japan has made a commitment to the world to reduce its 2008 2012 emissions of greenhouse gases by 6 from 1990 levels.
Portland blast furnace cement simply called slag cement refers to the hydraulic binding material ground by mixing Portland cement clinker, granular blast furnace slag, and appropriate amount of gypsum, code-named P S. The mixed amount of granular blast furnace slag in cement is
Jan 01, 2021 Therefore, it is worthwhile to consider slag cement concrete made with CS as a serious option for structural applications. Following inferences are obtained from the study by using CS as fractional replacement of FNA in slag cement concrete The copper slag, when substituted up to 40 replacement of FNA, enhanced the compressive strength.

Needs for concrete, being the major construction material has grown with the rapidly growing construction sector. Aggregate generally occupy about 70-80 of the volume of concrete used in buildings. The needs for alternative sources of aggregates are pressing. Steel slag, which is a by-product of steel manufacturing, could be an alternative ...
At construction with use of slag stone a little cement mortar leaves. The weight of this block material is very small, since it is inferior in density to ordinary brick. Due to this quality, it is permissible to use cinder blocks in the construction of buildings on lightweight foundations.
Portland slag cement CEM IIA-S 42,5 R is suitable for the production of higher cement grades, chemical building structures, for the production of reinforced concrete products, reinforced constructions and pre-stressed concrete. Technical Specifications Clinker ranging 80-94 BF Slag ranging 6-20 Produced according to EN 1971-2011 ...
The ground granulated blast furnace slag GGBFS is a by-product of iron manufacturing which when added to concrete improves its properties such as workability, strength and durability. This material is obtained by the heating of iron ore, limestone and coke at a temperature about 1500 degree Celsius. The process is carried out in a blast furnace.
Jan 15, 2019 Manufacturing companies and investors must be given incentives for adopting green cement manufacturing processes. Appointment of home inspectors will help keep records of buildings made of green cement, so that such buildings could be certified and builders rewarded.
