While the construction sector continues to grow, finding sustainable alternatives to concrete is quite important.

Traditional cement manufacturing utilises large reserves of raw materials such as for example limestone and cement, that are energy-intensive to extract and create. However, experts and business leaders such as Naser Bustami would likely mention out that integrating recycled materials such as recycled concrete aggregate or supplementary cementitious materials in the manufacturing process can lessen the carbon footprint substantially. RCA is procured from demolished structures and the recycling of concrete waste. Whenever construction businesses utilise RCA, they move waste from dumps while on top of that lowering their reliance on extra extraction of natural resources. On the other hand, studies have shown that RCA will not only be useful environmentally but also enhance the general quality of concrete. Incorporating RCA boosts the compressive strengths, toughness and immunity to chemical attacks. Similarly, supplementary cementitious materials can act as partial replacements for cement in concrete production. The most popular SCMs include fly ash, slag and silica fume, commercial by-products usually discarded as waste. When SCMs are included, it is often shown to make concrete resist various outdoor factors, such as for instance alterations in heat and exposure to harsh environments.

Cement generates huge levels of carbon dioxide; a green alternative could change that. Concrete, a vital construction material produced by combining concrete, sand, and gravel, could be the 2nd most consumed substance globally after water. Based on data on concrete, around 3 tonnes of the stuff are poured each year for every person. During production, limestone calcium carbonate is heated up, producing calcium oxide lime, emitting CO2 as a by-product. Experts determine CO2 emissions connected with concrete production become around eight per cent of global anthropogenic emissions, contributing considerably to man-made climate change. However, the interest in concrete is anticipated to increase due to population growth and urbanisation, as business leaders such as Amin Nasser and Nadhim Al Nasr would probably attest. Hence, industry experts and researchers are working on an innovative solution that curbs emissions while maintaining structural integrity.

There are lots of benefits to making use of concrete. As an example, concrete has high compressive power, which means it can resist heavy loads; this quality makes it especially suited to structural applications such as for instance building fundamentals, columns and beams. Furthermore, it could be strengthened by metal rods, what exactly is known as reinforced concrete, which exhibits also greater structural integrity. Furthermore, concrete constructs are proven to endure the test of time, enduring years and sometimes even hundreds of years. Additionally, this is a adaptable product; it could be formed into different sizes and shapes. This enables architects and designers to be imaginative using their choices. The adaptability and endurance are factors that make cement a favoured building product for all seeking both a visual appeal in addition to structural robustness.
