Concrete that traps co2 forever -Green Concrete

the world is expecting more than 2 trillion sq feet of new building space by 2060

that's the equivalent of adding another Hyderabad every month for the next 50 years. many of these buildings will be made using cement a massive emitter of greenhouse gases.it is the 2nd most consumed substance on the planet after water. cement industry generates approximately 8 percent of global CO2 emissions.if you consider the cement industry as a country then it would be the third-highest emitter after China and the United States.

Cement vs Concrete:

a simple analogy is if you consider cement as flour then concrete is a cake a finished product.concrete is a mixture of rocks, sands, water, and most importantly cement that binds it all together. without cement concrete doesn't hold up skyscrapers.to make cement we dig out limestone and run it through klin where it heated with very high temperatures of around 1500 degrees Celcius and during this process each 1000 kilogram of limestone produces a half a kilogram of co2. cement is the glue to make concrete it hardens the concrete and given the strength and compressibility that make concrete perfect for infrastructure 

Solution:

CO2 mineralization is a technology that introduces recycled CO2 into fresh concrete. CO2 is converted to a mineral and becomes permanently captured forever. and the best part of that it improves the compressive strength of the concrete. that right the real selling point here adding CO2 makes a concrete stronger that means concrete producers can use less cement in their mixtures and still achieve the same strength. less cement equals fewer emissions of CO2. This enables production efficiencies as well as carbon footprint reductions. this technology is invented by CarbonCure

Impact:

ultimately if this technology was deployed across the globe this could reduce 700 megatons of CO2 emission ("7 billion metric tones. total CO2 emission is around 36 billion metric ton") every year and that's the same as taking 150 million cars off the road every year or CO2 reduction from 500 million acres of trees annually.

business point of view:

concrete companies pay to use CarbonCure signature system and have to buy/trade CO2 from a factory where its emitted but they save money by using less of their most expensive ingredient cement. well we have to understand that to make environmental impacts we have to make business sense it's an environmentally friendly business model.

Final Words:

my inspiration to this blog post this video Climate Change, how covid19 impact all of us this show us what happens when human mess with mother nature. climate change is a reality we have to think about it. THINK HUMAN THINK!

and this blog helps me start with this

FBR’ a silly acronym that can help you to get started with anything

check it out if you really want to get started because at last it only matters 

how you feel about this climate change let me know and  let me know how you feel about this blog and please share it if you think it is impactful 

Namaste this is Anish Jain
