Slag cement is a hydraulic cement formed when granulated blast furnace slag is ground to fine pieces and used to replace a portion of Portland cement. It is a recovered byproduct of the iron manufacturing process. The use of slag cement demonstrated long-term performance enhancements enabling designers to decrease the environmental footprint of concrete while ensuring improved performance and enhanced durability.
As an iron byproduct, the molten slag diverted from the iron blast furnace is quickly chilled, creating glassy granules that yield desired reactive characteristics when ground into cement finesse.
The Benefits of Using Slag Cement
There are many different uses and applications of slag cement including ternary mixtures and soil stabilization to name a few. The advantages of using slag cement are:
------ Improved workability
------ Easier place ability and finish ability
------ Higher long-term compressive and flexural strengths
------ Decreased permeability.
------ ASR mitigation properties
------ Improved durability and resilience
------ More consistent performance
------ Lighter color
Strength and Durability of Slag Cement
Concrete made with slag cement offers greater compressive and flexural strengths as compared to Portland cement concrete. SCIC #14, Compressive and Flexural Strength analyses the factors that affect concrete strength and indicates how slag cement enhances both the compressive and flexural strength of concrete. advantages of higher strength include increased safety and reliability; optimized element designs that enable thinner, lighter, and fewer members in structures; optimized mixture designs that experience less shrinkage, curling, and heat; and lower life cycle costs through improved service life.
Slag Cement and Life Cycle Prediction Models, analyze how slag cement can positively affect some of the characteristics that enhance the useful life of a concrete structure and decrease life cycle cost. It includes low permeability, improved corrosion resistance, high strength, increased resistance to alkali-silica reactivity and sulfate attack and reduced thermal stress. This information sheet offers a short case study of a life cycle prediction model.
Slag Cement Specifications
A great primer for those new to the slag cement industry, SCIC #12, Terminology, and Specifications, provides definitions of 12 basic slag cement-related terms. It includes slag cement, granulated blast furnace slag, blended cement, hydraulic cement, and pozzolan. Standard ASTM specifications crucial for those working with slag cement are summarized, including ASTM C 989, ASTM C 595, and ASTM C 1157. Three pertinent ACI Committee reports also are combined. This information sheet is an amazing starting point for anyone who wants to learn more about using slag cement concrete.
