GGBS
Granulated Slag is a byproduct of the blast furnaces that are used to make iron. It is obtained by rapidly chilling the molten ash with the help of water. During this process, the slag gets fragmented and transformed into amorphous granules. The granulated slag is ground to desired fineness to produce GGBS.
Advantages of using Ecofines GGBS with cement:
- Higher durability
- Higher compressive & flexural strength
- Improved workability
- Replacing the Portland cement by GGBS helps reduce CO2 emissions. Replacement can go up to 70%.
- Since it is produced in a controlled environment, GGBS is more consistent than fly ash in concrete performance as it has better particle packing.
- Reduces the temperature rise in concrete and helps to avoid early-age thermal cracking.
MFGGBS
It is an ultrafine powder, especially processed by further grinding GGBS in a controlled environment. The computed blain value based on particle size distribution (PSD) is around 700-800 m2/kg and is truly ultra fine. This ultra fineness helps improve properties of regular GGBS like high surface area leading to an increase in the rate of hydration, improved particle packing leading to lower voids, and lower permeability leading to higher resistance to chemical attacks. In spite of its high fineness, it does not increase water demand at the dosage range of 5 to 15 percent of normal OPC in general. In fact, the concrete slump is seen to be improved, due to the dense packing of cementitious material, producing low void content.
Advantages of Ecofines Microfine GGBS:
- Since it is a specialized product with uniform PSD, it enhances the permeability which can find its application in high rise construction.
- High resistance against chemical attacks will help find its wide-scale application in ETP plants.
- Since corrosion is controlled due to lower permeability, it has marine applications such as dams, causeways, shore protection, etc.
- It can also be used as a silica replacement.
