Concrete production is a major contributor to CO2 emissions, but there is hope for a greener alternatives.

There are numerous benefits to using concrete. For example, concrete has high compressive power, meaning it could resist heavy lots; this quality makes it specially suited to structural applications such as building foundations, columns and beams. Furthermore, it may be reinforced by metal bars, what is known as reinforced concrete, which exhibits also greater structural integrity. Furthermore, concrete constructions are known to endure the test of time, enduring decades and sometimes even hundreds of years. Moreover, it is a flexible material; it could be moulded into various size and shapes. This enables architects and designers to be creative making use of their choices. The versatility and strength are factors which make concrete a favoured building product for all those seeking both a visual appeal in addition to structural robustness.

Cement produces huge levels of carbon dioxide; a green alternative could alter that. Concrete, a key construction product made by combining concrete, sand, and gravel, is the 2nd most consumed substance globally after water. In accordance with statistics on concrete, around 3 tonnes of this material are poured each year for every person. During production, limestone calcium carbonate is heated, creating calcium oxide lime, emitting CO2 being a by-product. Researchers calculate CO2 emissions connected with concrete production to be around eight % of global anthropogenic emissions, contributing notably to man-made climate change. However, the interest in concrete is expected to boost because of populace growth and urbanisation, as business leaders such as Amin Nasser and Nadhim Al Nasr would likely attest. Hence, industry experts and scientists will work on an revolutionary solution that curbs emissions while keeping structural integrity.

Conventional concrete manufacturing utilises large reserves of garbage such as limestone and concrete, that are energy-intensive to extract and create. But, industry experts and business leaders such as Naser Bustami would probably point out that integrating recycled materials such as recycled concrete aggregate or supplementary cementitious materials in the production procedure can reduce the carbon footprint significantly. RCA is gained from demolished structures plus the recycling of concrete waste. When construction companies utilise RCA, they re-purpose waste from landfills while on top of that lowering their reliance on extra removal of raw materials. Having said that, research reports have demonstrated that RCA can not only be useful environmentally but also improve the overall quality of concrete. Adding RCA improves the compressive robustness, longevity and resistance to chemical attacks. Likewise, supplementary cementitious materials can serve as partial replacements for cement in concrete production. The common SCMs consist of fly ash, slag and silica fume, commercial by-products often thrown away as waste. Whenever SCMs are incorporated, it has been proven to make concrete resist different outdoor factors, such as for instance alterations in temperature and experience of harsh environments.
