Concrete with slag cement will have a slower rate of strength gain than concrete made with 100 percent portland cement; however, the long-term strength of slag cement is comparable to or higher than the same concrete with all portland cement.
Two major uses of GGBS are in the production of quality-improved slag cement, namely Portland Blastfurnace cement (PBFC) and high-slag blast-furnace cement (HSBFC), with GGBS content ranging typically from 30 to 70%; and in the production of ready-mixed or site-batched durable concrete.
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.
In Building Materials in Civil Engineering, 2011. 4.2.3 Portland Blast Furnace Cement. 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 20% ~ 70% by weight.

Since slag is not commonly used as an aggregate, its properties were investigated in the first place. The possibility of application of slag as a coarse aggregate in structural concrete exposed to regular environmental conditions and exposed to fire or high temperatures was studied.
Recently the mechanical properties of high-strength concrete incorporating copper slag as coarse aggregates were investigated by Khanzadi and Behnood . The results showed that the use of copper slag aggregate compared to limestone aggregated resulted in a 28-day compressive strength improvement of about 10–15%, and a splitting tensile ...
When blended with cement, the ground granulated blast furnace slag becomes Portland blast furnace slag cement with the same properties as ordinary (Portland) cement. The advantages of this blast furnace slag cement, such as increasing strength over long periods of time, low heating speed when reacting with water, and high chemical durability ...
chemical composition and quantities of slag cement ppt Cement Composition - The Concrete Portal. Oxides in smaller quantities that are important for cement behaviour include .
HIGH-PERFORMANCE CELLULAR CONCRETE High-Performance Cellular Concrete [HPCC] has all the properties of cellular concrete and can achieve 55.37 MPa [8,000 psi]. Higher strengths can be produced with the addition of supplementary cementitious materials. Density and strengths can be controlled to meet specific structural and
Chemical Composition of Cement The raw materials used for the manufacture of cement consist mainly of lime, silica, alumina and iron oxide. These oxides interact with one another in the kiln at high temperature to form more complex compounds. The relative proportions of .
Two major uses of GGBS [2] are in the production of quality-improved slag cement, namely Portland Blast furnace cement (PBFC) and high-slag blast-furnace cement (HSBFC), with GGBS content ranging typically from 30 to 70% and in the production of ready-mixed or site-batched durable concrete.
Usage of steel slag in concrete as fine and/or coarse aggregate Gözde İnan Sezer* & Mert Gülderen Department of Civil Engineering, Ege University, İzmir, Turkey Received 27 September 2013; accepted 13 February 2015 In this study, the use of steel slag as fine and/or coarse aggregate in concrete .
Compound Composition of Clinker / Cement Four major compounds formed from the oxides under high temperature in the kiln Name (Oxide Notation) - Shorthand Tricalcium silicate (3 CaO.SiO 2) – C3S Dicalcium silicate (2 CaO.SiO 2) – C2S Tricalcium aluminate (3 CaO.Al 2O 3) – C3A Tetracalcium aluminoferrite (4 CaO.Al 2O 3. Fe 2O 3) – C4AF
Dec 04, 2017· This video introduces fly ash, slag and silica fume and discusses their properties. ... Comparing fly ash, slag, and silica fume performance in concrete. - .
centage of slag cement expressed as a whole number by mass of the final blended cement. Thus, Type IS(25) is cement that contains 25 percent slag cement. • Type IT(aX)(By) to indicate ternary (T) blend-ed cement in which the "a" refers to the type of SCM (either "P" for pozzolan or "S" for slag
Cement containing large amounts of alkali can cause some difficulty in regulating the setting time of cement. Low alkali cement, when used with calcium chloride in concrete, can cause discoloration. In slag-lime cement, ground granulated blast furnace slag is not hydraulic on its own but is "activated" by addition of alkalis.
Supplementary cementing materials (SCMs) contribute to the properties of hardened concrete through hydraulic or pozzolanic activity. Typical examples are fly ashes, slag cement (ground, granulated blast-furnace slag), and silica fume. These can be used individually with portland or blended cement or in different combinations.
High strength concrete and high-performance concrete are not synonymous because strength and performance of concrete are different properties of concrete. High-strength concrete is defined based on its compressive strength at a given age. During 1970s, any concrete mixtures which showed 40 MPa or ...
Apr 17, 2017· I had practically used PPC cement in almost all projects. I didn't find any problem. Portland Slag Cement (PSC) Portland Slag Cement (PSC) is manufactured by either inter-grinding in the Portland cement clinker, Gypsum & Granulated Slag or blendin...
May 09, 2018· Ground Granulated Blast Furnace Slag (GGBS) The importance of Ground Granulated Blast Furnace Slag (GGBS) lies in its greener way to become a substitute in concrete material. GGBS being a waste material, it needs proper method for disposal. So incorporating this waste material in concrete can reduce the depletion of conventional concrete components such as cement, fine .
They include Portland cement as covered by AASHTO M85 (2), Portland blast furnace slag cement (blended cement type IS), and slag cement (slag cement type S) as per AASHTO M240. (3) The use of GGBFS as a partial Portland cement replacement takes advantage of the energy invested in the slag making process and its corresponding benefits with ...
