Because the construction sector is growing, finding sustainable alternatives to concrete is quite important.

Cement generates huge quantities of carbon dioxide; a green alternative could alter that. Concrete, an integral construction material made by combining cement, sand, and gravel, is the second most consumed substance globally after water. According to statistics on concrete, around 3 tonnes of this stuff are poured each year for everyone. During production, limestone calcium carbonate is heated, creating calcium oxide lime, emitting CO2 being a by-product. Researchers determine CO2 emissions connected with concrete production to be around eight % of global anthropogenic emissions, adding notably to man-made climate change. Nonetheless, the interest in concrete is expected to increase because of population development and urbanisation, as business leaders such as Amin Nasser and Nadhim Al Nasr may likely attest. Hence, industry experts and scientists are working on an revolutionary solution that reduce emissions while keeping structural integrity.

There are lots of advantages to making use of concrete. For instance, concrete has high compressive strength, this means it may withstand heavy loads; this feature makes it specially suited to structural applications such as building fundamentals, columns and beams. Moreover, it could be strengthened by metal rods, what exactly is known as reinforced concrete, which exhibits even greater structural integrity. Furthermore, concrete structures are known to survive the test of time, enduring decades and on occasion even hundreds of years. Furthermore, this is a flexible material; it can be formed into various shapes and sizes. This allows architects and designers become creative with their alternatives. The versatility and strength are factors which make concrete a favoured building product for all seeking both a visual appeal along with structural robustness.

Traditional cement manufacturing utilises large reserves of recycleables such as for instance limestone and concrete, that are energy-intensive to extract and produce. Nevertheless, industry experts and business leaders such as Naser Bustami may likely point also that incorporating recycled materials such as recycled concrete aggregate or supplementary cementitious materials within the manufacturing procedure can slash the carbon footprint considerably. RCA is acquired from destroyed structures as well as the recycling of concrete waste. Whenever construction businesses utilise RCA, they re-purpose waste from dumps while at precisely the same time reducing their reliance on extra extraction of raw materials. On the other hand, studies have confirmed that RCA can not only be useful environmentally but additionally increase the overall quality of concrete. Adding RCA increases the compressive strengths, toughness and resistance to chemical attacks. Similarly, additional cementitious materials can act as partial replacements for concrete in concrete manufacturing. The most popular SCMs include fly ash, slag and silica fume, commercial by-products frequently thrown away as waste. When SCMs are incorporated, it has been shown to make concrete resist different external conditions, such as for instance changes in heat and exposure to harsh surroundings.
