Experts contend that recycled materials and supplementary cementitious materials can control emissions without compromising structural integrity.

There are many advantages to making use of concrete. As an example, concrete has high compressive power, this means it may tolerate heavy lots; this characteristic makes it specially suitable for structural applications such as building fundamentals, columns and beams. Moreover, it can be reinforced by steel bars, what exactly is known as reinforced concrete, which exhibits even greater structural integrity. Also, concrete structures have been known to survive the test of time, lasting decades and on occasion even hundreds of years. Additionally, it is a flexible material; it may be formed into different size and shapes. This allows architects and engineers to be creative with their choices. The flexibility and strength are considerations which make concrete a favoured building material for all those seeking both a visual appeal also structural robustness.

Traditional cement manufacturing utilises large reserves of raw materials such as for instance limestone and concrete, that are energy-intensive to draw out and create. However, industry experts and business leaders such as Naser Bustami would probably mention also that integrating recycled materials such as recycled concrete aggregate or supplementary cementitious materials into the production process can reduce the carbon footprint significantly. RCA is collected from demolished buildings and also the recycling of concrete waste. When construction companies utilise RCA, they move waste from landfill sites while at exactly the same time bringing down their reliance upon extra extraction of raw materials. On the other hand, studies have demonstrated that RCA will not only be beneficial environmentally but also improve the general grade of concrete. Adding RCA improves the compressive strengths, durability and resistance to chemical attacks. Similarly, additional cementitious materials can act as partial substitutes for cement in concrete manufacturing. The common SCMs consist of fly ash, slag and silica fume, commercial by-products frequently discarded as waste. When SCMs are incorporated, it is often demonstrated to make concrete resist different external factors, such as alterations in heat and contact with harsh environments.

Cement produces huge quantities of carbon dioxide; a green alternative could alter that. Concrete, an integral construction material made by combining concrete, sand, and gravel, could be the second most consumed substance globally after water. In accordance with data on concrete, around three tonnes of this material are poured every year for every person. During manufacturing, limestone calcium carbonate is heated up, creating calcium oxide lime, emitting CO2 being a by-product. Scientists determine CO2 emissions connected with concrete production to be around eight per cent of global anthropogenic emissions, adding notably to man-made climate change. Nonetheless, the demand for concrete is expected to boost as a result of populace growth and urbanisation, as business leaders such as Amin Nasser and Nadhim Al Nasr may likely attest. Thus, experts and researchers are working for an innovative solution that reduce emissions while maintaining structural integrity.
