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

There are lots of advantages to making use of concrete. As an example, concrete has high compressive energy, this means it can tolerate heavy loads; this trait causes it to be particularly suitable for structural applications such as for instance building foundations, columns and beams. Moreover, it could be reinforced by metal rods, what is known as reinforced concrete, which exhibits also greater structural integrity. Additionally, concrete structures are known to endure the test of time, lasting decades and sometimes even hundreds of years. Furthermore, this is a flexible product; it may be moulded into different sizes and shapes. This permits architects and designers to be imaginative with their alternatives. The flexibility and toughness are points that make cement a favoured building material for all seeking both an aesthetic appeal also structural robustness.

Cement produces huge levels of carbon dioxide; a green alternative could alter that. Concrete, an integral construction product produced by combining concrete, sand, and gravel, may be the 2nd most consumed substance globally after water. In accordance with statistics on concrete, around 3 tonnes of this material are poured each year for everyone. During manufacturing, limestone calcium carbonate is heated up, producing calcium oxide lime, emitting CO2 being a by-product. Scientists determine CO2 emissions associated with concrete production become around eight % of global anthropogenic emissions, contributing notably to man-made climate change. However, the interest in concrete is expected to boost due to populace development and urbanisation, as business leaders such as Amin Nasser and Nadhim Al Nasr would probably attest. Therefore, experts and researchers will work for an innovative solution that reduce emissions while keeping structural integrity.

Traditional cement manufacturing utilises large reserves of raw materials such as for instance limestone and concrete, which are energy-intensive to extract and create. However, experts and business leaders such as Naser Bustami would probably point also that integrating recycled materials such as recycled concrete aggregate or supplementary cementitious materials in the production procedure can reduce the carbon footprint significantly. RCA is obtained from demolished structures plus the recycling of concrete waste. When construction companies utilise RCA, they re-purpose waste from landfills while on top of that bringing down their dependence on additional removal of natural resources. On the other hand, studies have confirmed that RCA will not only be beneficial environmentally but also increase the general quality of concrete. Incorporating RCA improves the compressive robustness, longevity and resistance to chemical attacks. Similarly, supplementary 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 frequently thrown away as waste. Whenever SCMs are incorporated, it has been proven to make concrete resist various outdoor conditions, such as for example alterations in temperature and exposure to harsh environments.
