Traditional concrete production practices must certainly be altered to reduce CO2 emissions.

There are numerous advantages to making use of concrete. For instance, concrete has high compressive strength, which means that it could withstand hefty loads; this trait makes it particularly suited to structural applications such as building fundamentals, columns and beams. Moreover, it could be reinforced by metal bars, what exactly is referred to as reinforced concrete, which exhibits also greater structural integrity. Also, concrete structures are known to endure the test of time, lasting years as well as hundreds of years. Moreover, this is a flexible product; it can be formed into various size and shapes. This allows architects and designers to be imaginative with their choices. The versatility and strength are considerations that make cement a favoured building material for all those seeking both an aesthetic appeal along with structural robustness.

Cement generates huge quantities of co2; a green alternative could change that. Concrete, an integral construction product made by combining concrete, sand, and gravel, is the second most used substance globally after water. According to data on concrete, around 3 tonnes of this material are poured every year for every person. During production, limestone calcium carbonate is heated, producing calcium oxide lime, emitting CO2 as being a by-product. Scientists calculate CO2 emissions connected with concrete production to be around eight percent of global anthropogenic emissions, adding significantly to man-made climate change. However, the interest in concrete is expected to increase as a result of population growth and urbanisation, as business leaders such as Amin Nasser and Nadhim Al Nasr would likely attest. Therefore, experts and scientists are working on an revolutionary solution that reduce emissions while maintaining structural integrity.

Traditional cement manufacturing utilises large reserves of garbage such as limestone and cement, that are energy-intensive to draw out and create. Nevertheless, experts and business leaders such as Naser Bustami would probably mention out that incorporating recycled materials such as recycled concrete aggregate or supplementary cementitious materials within the manufacturing procedure can reduce the carbon footprint significantly. RCA is gained from demolished buildings and also the recycling of concrete waste. Whenever construction businesses utilise RCA, they re-purpose waste from landfills while on top of that decreasing their reliance upon additional extraction of raw materials. On the other hand, studies have confirmed that RCA can not only be useful environmentally but also improve the overall quality of concrete. Incorporating RCA enhances the compressive robustness, longevity and immunity to chemical attacks. Likewise, additional cementitious materials can act as partial substitutes for concrete in concrete manufacturing. The common SCMs include fly ash, slag and silica fume, industrial by-products often discarded as waste. When SCMs are incorporated, it has been shown to make concrete resist various external factors, such as for instance changes in temperature and contact with harsh environments.
