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.
In our area, people are discussing the benefits or disadvantages of finishing exterior concrete containing ground granulated blast furnace (GGBF) slag. One group claims that since slag is finer than portland cement, a finisher brings more fines to the surface after straight edge and floating and thus creates a less durable surface. Another group suggests that the excess fines in a flatwork .
Slag cement, often called ground granulated blast-furnace slag (GGBFS), is one of the most consistent cementitious materials used in concrete. It is actually a byproduct of iron production. When the iron is processed using a blast furnace, slag and iron both collect at the bottom of the furnace.The molten slag must first be separated from the molten iron.
Clinker is often replaced with supplementary cementitious materials (SCM) such as granulated blast furnace slag, natural pozzolanes and fly ash in order to reduce CO 2 emissions and material cost. However, SCM may counteract strength development, powder flowability, mortar workability and durability, which are critical for cement quality.

Hardened concrete containing slag cement can show mottled green or blue-green areas on the surface in the first few days after placement. This temporary condition commonly is called “greening.” Surface greening occurs in only a small percentage of concrete made with slag cement and does not affect concrete performance.
Slag is often used in combination with other pozzolan in blending with Portland cement for making masonry cement. Fonseca (2012) managed to make good masonry cement with only 20% ordinary Portland cement and the rest consisting of 25% FA and 55% slag. The same author showed that the 28-day compressive strength obtained complied with the requirement for class S masonry mortar as per ASTM C91 .
Slag cement requires nearly 90% less energy to produce than portland cement. According to the Slag Cement Association, substituting 50% slag cement for portland cement reduces greenhouse gas emissions by more than 40% and lowers the embodied energy of concrete by more than 30%. Another factor is slag cement’s nearly white color. Lighter .
Slag When added to concrete, GGBFS enhances a range of performance characteristics such as the reduction of the heat of hydration in mass concrete pours, reduction of concrete permeability and improvement of durability properties in resistance to aggressive environments.

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.
