2. Ground-Granulated Blast-furnace Slag Sometimes, also referred to as GGBFS Obtained by quenching molten iron slag from a blast furnace in water or steam, dried and ground into a fine powder. 3. Chemicals Present in GGBS CaO 30-50% SiO2 28-38% Al2O3 8-24% MgO 1-18% MnO 0.68% TiO2 0.58% K2O 0.37% N2O 0.27%.

Slag cement is as old as iron-making itself. In the 1700s, it was combined with lime to make mortar. One of the first major uses of slag-lime cements was construction of the Paris underground in the late 1800s. In the U.S., blends of slag and portland cements were introduced in 1896. Today, slag cement can account for 30% to 50% of the cement ...

Slag cement and some pozzolans with high calcium contents. No calcium hydroxide byproduct; may consume calcium hydroxide from system. Reactivity dependant on fineness and composition of slag cement, temperature, and alkali content of portland cement. Slag cement is referred to as a latent hydraulic material.

Setting Time Cement paste setting time is affected by a number of items including: cement fineness, water-cement ratio, chemical content (especially gypsum content) and admixtures. For construction purposes, the initial set must not be too soon and the final set must not be too late.

In my opinion, PSC (Premium Slag Cement) fits the most. Because of the construction qualities, it is ideal for house construction. PSC is a blended cement. Slag is a product that is non-metallic and is 90% glass. With silicates of lime, these qualities make the …

Introduction Cement is a building material for binding bricks, stones or aggregates. Used for making mortar or concrete. Cements natural and artificial. Natural cement-burning and crushing of stones and lime. Artificial cement-burning at high temperature and gypsum is added. 4. Lime- excess will decrease the strength.

In developing countries, there is a necessity for sophisticated buildings and High Strength Concrete (HSC). In this study, the HSC of grade M65 with a slump of 100mm and w/c of 0.28 is considered. The fine aggregate of the concrete is replaced …
