Influence of steel slag on mechanical properties and ...

2013-10-1  The negative effect of steel slag on the compressive strength, permeability, and carbonation resistance of concrete is weaker at lower W/B. At high W/B, steel slag tends to accelerate the development of drying shrinkage at the early ages, but it has an insignificant influence on the ultimate shrinkage at 90 days.

Effect of blast-furnace slag as cement replacement on ...

Sustainability is getting more and more attention during the last years. Also in the concrete and cement industry, attempts are made to minimize the environmental impact. One way to implement this thought, is the use of industrial by-products as cement replacing material. The 'waste' products are upgraded in high-value applications and the need for clinker is reduced.

Durability Properties of Concrete with GGBS

Effect of GGBFS of durability properties of concrete is discussed in this article. Durability is an important factor that must be appreciable for any structure so that it is performing for the requirement for which it is built for. It is a time period requirement. Every structure irrespective of what material is employed should gain this property.
