Predicting the compressive strength of ground …
01-05-2009 · However, hydration of ground granulated blast furnace slag is much more sensitive to temperature than Portland cement and the strength development of ground granulated blast furnace slag concrete is considerably slower under standard 20 °C curing conditions than that of Portland cement concrete, although the ultimate strength is higher for the same water–binder ratio , , .
NewCem | Lafarge Canada
When slag is separated from iron and rapidly cooled with water (granulated), the morphology of the slag changes. This morphology change provides the slag with its cementitious properties. The granulated slag is then ground to a controlled fineness, typically greater than that of GU portland cement, and the finished product, called ground granulated blast furnace slag (GGBFS) is ready for ...
GGBS - Ground Granulated Blast Furnace Slag for …
07-10-2019 · Granulated slag is then ground to desired fineness for producing ground granulated blast furnace slag. Also Read: Wet Process for Manufacturing of Cement Concrete made with GGBS cement sets more slowly as compared to ordinary concrete and its setting time depends on the amount of GGBS in the cementitious material, but it endures to gain strength over a longer period.

Keywords: blast-furnace slag; compressive strength; concretes; curing; low temperature. Date: 1/1/2000. Abstract: This stone presents the effect of mixture proportions and curing method on the strength development of concrete incorporating high levels of ground granulated blast-furnace slag (GGBS) at low temperatures.
Ground Granulated Blastfurnace Slag
When Ground Granulated Blastfurnace Slag is blended with cement or added to the concrete mixer the amount of soluble SO3 and C3A is reduced in proportion to the slag added. While we are not aware of any difficulties in setting times or admixture performance we advise comprehensive mix trials especially at high slag replacement levels to check workability.

A comparative assessment of the mechanical properties of concrete containing electric arc furnace (EAF) oxidizing slag and granulated blast furnace (GBF) slag was performed. The goal was to investigate the effects of the substitution of EAF oxidizing slag and GBF slag for cement, in order to examine the possibility of using EAF oxidizing slag as a binder.
What is slag cement
Slag cement, or ground granulated blast furnace slag (GGBFS), has been incorporated into concrete projects in the U.S. for over a century to improve durability and reduce life cycle costs. Among its measurable benefits in concrete are better workability and finishability, higher compressive and flexural strengths, and improved resistance to aggressive chemicals.
