Concrete production is a leading factor to CO2 emissions, but there clearly is hope for an environmentally friendly options.

There are numerous advantages to utilizing concrete. For instance, concrete has high compressive power, which means that it may withstand heavy lots; this trait makes it particularly ideal for structural applications such as building fundamentals, columns and beams. Furthermore, it could be strengthened by metal bars, what is referred to as reinforced concrete, which exhibits also greater structural integrity. Furthermore, concrete constructions are recognized to survive the test of time, lasting decades or even hundreds of years. Furthermore, this is a flexible material; it can be moulded into different size and shapes. This permits architects and designers to be creative making use of their alternatives. The flexibility and strength are factors that make cement a favoured building material for all seeking both a visual appeal as well as structural robustness.

Cement generates huge levels of carbon dioxide; a green alternative could change that. Concrete, a vital construction material made by combining concrete, sand, and gravel, is the 2nd most used substance globally after water. According to data on concrete, around three tonnes of the material are poured each year for everyone. During manufacturing, limestone calcium carbonate is heated up, producing calcium oxide lime, emitting CO2 as being a by-product. Experts determine CO2 emissions associated with concrete production become around eight percent of global anthropogenic emissions, contributing dramatically to man-made climate change. Nevertheless, the interest in concrete is expected to boost due to populace growth and urbanisation, as business leaders such as Amin Nasser and Nadhim Al Nasr would probably attest. Therefore, experts and researchers will work on an innovative solution that reduce emissions while maintaining structural integrity.

Conventional concrete manufacturing utilises large reserves of recycleables such as limestone and cement, that are energy-intensive to extract and create. Nevertheless, experts and business leaders such as Naser Bustami would likely point also that incorporating recycled materials such as recycled concrete aggregate or supplementary cementitious materials into the production process can minimise the carbon footprint significantly. RCA is gained from demolished buildings plus the recycling of concrete waste. When construction businesses utilise RCA, they divert waste from landfill sites while in addition bringing down their dependence on extra extraction of natural resources. On the other hand, research reports have found that RCA can not only be beneficial environmentally but also increase the overall quality of concrete. Adding RCA increases the compressive strengths, toughness and immunity to chemical attacks. Similarly, supplementary cementitious materials can act as partial substitutes for cement in concrete manufacturing. The common SCMs consist of fly ash, slag and silica fume, industrial by-products frequently thrown away as waste. When SCMs are included, it is often shown to make concrete resist various outdoor conditions, such as changes in heat and experience of harsh environments.
