The influence of slag content on compressive strengths of High Volumes Slag Concrete (cement: GGBS = 50:50 is considered) is investigated for 28 days and 90 days. Specimens of …
Pozzolana cement and blast-furnace slag cement have many common grounds in performance (see Table 4.6), such slow hydration, setting and hardening process, low early strength, high growth of the later strength, low heat of hydration, high corrosion, poor frost-resistance, and easy carbonization. The water demand of pozzolana cement is large.
difference in the level of deicer scaling that occurred in slag cement concrete versus OPC concrete (Dubovoy, et al, 1986). Afrani and Rogers (1994), on the other hand, recorded much greater scaling loss for concrete with high slag cement replacement compared to OPC concrete. Also noted was a difference in deicer scaling resistance apparently

Slag cement is a hydraulic cement formed when granulated blast furnace slag (GGBFS) is ground to suitable fineness and is used to replace a portion of portland cement. It is a recovered industrial by-product of an iron blast furnace.
Jun 30, 2020· In this study, the Portland cement (C 3 S:47.5%, C 3 A:6.9%) by the China Cement Corporation was used. Furthermore, ground granulated blast furnace slag was added as supplementary cementing material. The chemical composition of the used binders is listed in Table 1.The natural river sand with a fineness modulus of 2.8 and a saturated surface dry specific gravity of 2.75 was used as …

In France, these slag cements were used as early as 1889 to build the Paris underground metro system (Thomas 1979). Mary (1951) described the preparation of slag cement ...
Cement Type Description Type IL Portland-Limestone Cement Type IS Portland-Slag Cement Type IP Portland-Pozzonlan Cement Type IT Ternary Blended Cement. In addition, some blended cements have special performance properties verified by additional testing.
Proportioning Concrete with Slag Cement. Concrete mixtures containing slag cement should be proportioned according to ACI 211.1. The specific gravity of slag cement ranges from 2.85 to 2.94, depending on the slag source, as compared to 3.15 for portland cement.
Slag Cement (France) NATIONAL SLAG ASSOCIATION Page 5 There is a big opportunity for a large development in the use of slag considering the fact that not more than 30% fly ash or pumice can be employed in concrete. 6. SLAG CEMENT USES The market for slag cement includes the following principal uses:
Slag cement increases the compressive and flexural strength of conventional concrete (Figures 1 and 2) and is often a vital component in producing high strength concrete. 28-day strengths generally increase as the percentage of slag cement increases, up to about50 percent slag cement as a percent of cementitious material.
Portland Blast-furnace Slag Cement. A Portland cement mixed with a designated amount of ground granulated blast-furnace slag. The latent hydraulic property of the blast-furnace slag gives excellent long-term strength. Properties Significant chemoresistance, and Suppression of alkali-aggregate reaction (type B and C). Applications
Ground-granulated blast-furnace slag is obtained by quenching molten iron slag from a blast furnace in water or steam, to produce a glassy, granular product that is then dried and ground into a fine powder. Ground-granulated blast furnace slag is highly cementitious and high in CSH which is a strength enhancing compound which improves the strength, durability and appearance of the concrete.
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. Its use is well established in the construction industry in producing durable ...
Pozzolana cement and blast-furnace slag cement have many common grounds in performance (see Table 4.6), such slow hydration, setting and hardening process, low early strength, high growth of the later strength, low heat of hydration, high corrosion, poor frost-resistance, and easy carbonization. The water demand of pozzolana cement is large.
Steel slag is an industrial by-product of steel industry. It possesses the problem of disposal as waste and is of environmental concern. The results were compared with conventional concrete ...
Color of concrete incorporating slag. Due to light color of blast furnace slag, color of slag concrete is lighter in comparison with conventional concrete. Moreover, deep blue-green color shown by interior part of slag concrete and can be noticed from slag concrete broken parts, for …
Proportioning Concrete with Slag Cement. Concrete mixtures containing slag cement should be proportioned according to ACI 211.1. The specific gravity of slag cement ranges from 2.85 to 2.94, depending on the slag source, as compared to 3.15 for portland cement.
SPECIAL CEMENT WITH A VERY HIGH SLAG CONTENT FOR ROAD CONSTRUCTION CIMENTS SPECIAUX A TRES HAUTE TENEUR EN LAITIER POUR UTILISATION ROUTIERE. The standard gravel-cement technique offers various advantages regarding cost, availability of the binder, and mechanical performance.
Aug 16, 2007· Slag is expense, about the same cost of portland cement, but worth it. The strength gains between slag and flyash are quite different. Slag is a "hydrate" than flyash and you get the bang for buck, in 16-20 hours strengths, especially in hot weather. Slag isn't cheap, just about the same cost as cement, but in my book, its worth every penny you ...
