As the construction sector is growing, finding sustainable options to concrete is quite important.

There are numerous advantages to using concrete. As an example, concrete has high compressive strength, meaning it can resist hefty loads; this characteristic causes it to be particularly suited to structural applications such as for instance building foundations, columns and beams. Furthermore, it could be reinforced by metal bars, what is known as reinforced concrete, which exhibits also greater structural integrity. Additionally, concrete constructs have been recognized to endure the test of time, lasting years and even hundreds of years. Furthermore, it is a adaptable material; it can be moulded into different shapes and sizes. This allows architects and designers become innovative with their choices. The flexibility and toughness are aspects that make cement a favoured building product for all those seeking both a visual appeal along with structural robustness.

Cement produces huge levels of co2; a green alternative could alter that. Concrete, an integral construction product created by combining concrete, sand, and gravel, could be the 2nd most consumed substance globally after water. In accordance with data on concrete, around three tonnes of this stuff are poured each year for everyone. During manufacturing, limestone calcium carbonate is heated, producing calcium oxide lime, emitting CO2 as being a by-product. Researchers determine CO2 emissions associated with concrete production to be around eight percent of global anthropogenic emissions, contributing considerably to man-made climate change. However, the demand for concrete is expected to increase due to population growth and urbanisation, as business leaders such as Amin Nasser and Nadhim Al Nasr would likely attest. Thus, industry experts and scientists will work for an innovative solution that curbs emissions while keeping structural integrity.

Conventional concrete manufacturing utilises large reserves of raw materials such as limestone and cement, that are energy-intensive to draw out and produce. However, industry experts and business leaders such as Naser Bustami would likely mention out that incorporating recycled materials such as recycled concrete aggregate or supplementary cementitious materials into the manufacturing process can slash the carbon footprint substantially. RCA is collected from demolished buildings and the recycling of concrete waste. Whenever construction companies utilise RCA, they divert waste from landfills while in addition lowering their reliance upon additional extraction of natural resources. On the other hand, research reports have discovered that RCA can not only be beneficial environmentally but additionally improve the general grade of concrete. Incorporating RCA increases the compressive robustness, durability and immunity to chemical attacks. Similarly, additional cementitious materials can serve as partial replacements for concrete in concrete manufacturing. The common SCMs consist of fly ash, slag and silica fume, commercial by-products frequently thrown away as waste. When SCMs are included, it has been proven to make concrete resist different external factors, such as for instance alterations in temperature and contact with harsh environments.
