Believe it or not. After water, concrete is the most widely used substance on Earth. The claim of mankind in cementing relation with its environment has failed miserably, yet he thinks concrete is the foundation of modern development. It provides a structure for healthcare, education, energy and industry in natural disasters.
We truly enjoy having a roof over our heads and mud off our feet when discussing concrete. Yet, concrete is part and parcel of our lives. Everywhere we go, we use concrete. In our homes, in our schools, in our offices, on the pavements, on the roads, and in hospitals. Even when we flush the toilet, we use concrete. This is why we often measure modern development in terms of concrete.
Our built environment has been greatly influenced by it, but as they say, everything comes at a cost, which comes at a huge environmental price.
Cement is a crucial ingredient in concrete. A study found that “cement which we use on a global scale over 4 billion tons every year, its production alone generates around 2.5 billion tonnes of carbon dioxide (CO2) per year—about 8% of the global total.
Making cement requires using long rotating kilns for the length of two football pitches, which are heated to around 1,500°C. The chemical process which turns the raw material of limestone and clay into cement also releases high levels of CO2. However, the environmental impact of concrete goes further than a large amount of CO2 released into the atmosphere through cement production.
Such widespread use of concrete is also exhausting our diminishing supplies of useable sand. Moreover, concrete consumes almost 10% of the world’s industrial water supplies.
