Traditional concrete production methods needs to be changed to reduce CO2 emissions.

There are lots of benefits to using concrete. For example, concrete has high compressive power, meaning it may endure hefty loads; this characteristic makes it specially suitable for structural applications such as for instance building foundations, columns and beams. Furthermore, it may be reinforced by steel bars, what is known as reinforced concrete, which exhibits also greater structural integrity. Furthermore, concrete structures are proven to endure the test of time, enduring years if not hundreds of years. Also, it is a flexible material; it can be formed into different shapes and sizes. This permits architects and designers become innovative with their choices. The flexibility and strength are aspects which make concrete a favoured building material for all those seeking both a visual appeal in addition to structural robustness.

Cement generates huge levels of co2; a green alternative could alter that. Concrete, a key construction product made by combining cement, sand, and gravel, could be the 2nd most consumed substance globally after water. Based on statistics on concrete, around 3 tonnes of the material are poured every year for every person. During production, limestone calcium carbonate is heated up, producing calcium oxide lime, emitting CO2 as a by-product. Scientists calculate CO2 emissions connected with concrete production to be around eight % of global anthropogenic emissions, adding significantly to man-made climate change. Nonetheless, the interest in concrete is expected to increase due to populace development and urbanisation, as business leaders such as Amin Nasser and Nadhim Al Nasr would probably attest. Hence, industry experts and researchers are working for an revolutionary solution that curbs emissions while maintaining structural integrity.

Conventional cement manufacturing utilises large reserves of garbage such as for instance limestone and cement, which are energy-intensive to draw out and create. Nevertheless, industry experts and business leaders such as Naser Bustami would probably point out that integrating recycled materials such as recycled concrete aggregate or supplementary cementitious materials into the production process can minimise the carbon footprint considerably. RCA is procured from demolished buildings plus the recycling of concrete waste. When construction companies utilise RCA, they re-purpose waste from dumps while at precisely the same time decreasing their dependence on extra extraction of raw materials. Having said that, studies have revealed that RCA can not only be beneficial environmentally but also increase the overall grade of concrete. Incorporating RCA increases the compressive robustness, durability and immunity to chemical attacks. Similarly, additional cementitious materials can serve as partial substitutes for concrete in concrete manufacturing. The most popular SCMs include fly ash, slag and silica fume, industrial by-products frequently discarded as waste. Whenever SCMs are incorporated, it is often shown to make concrete resist different external conditions, such as for instance alterations in temperature and exposure to harsh surroundings.
