Because the construction sector is growing, finding sustainable options to concrete is quite essential.

There are lots of advantages to making use of concrete. As an example, concrete has high compressive energy, this means it can tolerate hefty loads; this trait causes it to be especially suitable for structural applications such as for instance building fundamentals, columns and beams. Moreover, it can be strengthened by steel rods, what exactly is referred to as reinforced concrete, which exhibits also greater structural integrity. Furthermore, concrete frameworks have been proven to endure the test of time, lasting years and on occasion even hundreds of years. Moreover, this is a flexible material; it could be moulded into various size and shapes. This enables architects and engineers become imaginative with their alternatives. The flexibility and endurance are points that make cement a favoured building material for all seeking both a visual appeal as well as structural robustness.

Cement generates huge quantities of co2; a green alternative could change that. Concrete, a vital construction material created by combining cement, sand, and gravel, is the 2nd most consumed substance globally after water. Based on 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 per cent of global anthropogenic emissions, adding significantly to man-made climate change. However, the demand for concrete is expected to boost because of population development and urbanisation, as business leaders such as Amin Nasser and Nadhim Al Nasr may likely attest. Thus, industry experts and scientists are working for an innovative solution that curbs 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 draw out and produce. Nonetheless, industry experts and business leaders such as Naser Bustami may 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 considerably. RCA is collected from demolished structures and the recycling of concrete waste. When construction businesses utilise RCA, they divert waste from landfill sites while as well decreasing their reliance upon additional removal of natural resources. On the other hand, research reports have shown that RCA will not only be useful environmentally but additionally improve the overall quality of concrete. Adding RCA increases the compressive strengths, toughness and immunity to chemical attacks. Likewise, supplementary cementitious materials can serve as partial substitutes for concrete in concrete production. The common SCMs include fly ash, slag and silica fume, commercial by-products usually thrown away as waste. When SCMs are incorporated, it has been proven to make concrete resist different external factors, such as for instance alterations in heat and exposure to harsh environments.
