  1. 1. THE CO2 NEGATIVE CEMENT FERROCK OVERVIEW CO2 EMISSION
  2. 2. CEMENT  It’s been called the foundation of modern civilization. Portland cement, the generic name, is the glue that allows concrete to harden. And concrete is everywhere, in highways, bridges, sidewalks, buildings of all sizes, and much more.  Four billion tons of cement is manufactured each year worldwide, a half-ton for every person on Earth.
  3. 3. NEED OF SUBSTITUTE FOR CEMENT  Climate change has prompted scientists to search for new ways to reduce greenhouse gases in all kinds of fields.  alternative to the unlikely cause of fully 7 percent of the world’s carbon dioxide emissions.  For every one ton of cement produced approximately .8 ton of co2 is released.  It’s incredibly polluting. Problem is, we can’t really get away from cement, considering we need it to build a whole lot of structures.
  4. 4. CO2 EMISSION CHART
  5. 5. INRODUCTION TO FERROCK  Created by David Stone back when was a PhD student,  A key ingredient is iron, something he gets from steel mill. discovered that there was this material called steel dust that is not recycled. So, it typically goes straight to the landfill.
  6. 6. PROPERTIES OF FERROCK  Stone’s material, called Ferrock for the iron.  When you talk to anybody about concrete, the first thing that they will ask you is, what’s the strength?  Compressive strength tests show the pure paste (without aggregate) to be stronger than comparable samples of Portland cement  Flexural strength tests show the pure paste to be four times stronger than comparable samples of Portland cement.
  7. 7. PROPERTIES OF FERROCK contd..  Analysis (atomic absorption spectroscopy) shows that fully cured samples contain between 8 and 11% captured CO2 by weight. Ferrock is therefore "carbon negative" unlike Portland cement, which during manufacture is a major source of CO2 and other air pollutants.
  8. 8. OKLAHOMA CITY BOMBING
  9. 9. Professor Narayanan Neithalath, a civil engineer who develops sustainable materials, is testing Ferrock.  According to his study -:  What happened in Oklahoma City bombing(April 19, 1995) was the explosion demolished all the columns of the building and the building crashed because of the weight of it and the columns not being able to support them.  But if I have a blast-resistant material, so something made out of this material, what you will have is the — the columns will still become weaker. But it won’t collapse just like that, and you will save loss of lives and loss of property.
  10. 10. CONCLUSION It’s a golden opportunity for countries like INDIA and CHINA as being the global leaders in cement production to move a step forward towards a greener and sustainable future by adopting FERROCK as the substitute to traditional cement..
