Concrete production is major contributor to CO2 emissions, but there clearly was hope for greener options.

In the last couple of years, the construction sector and concrete production in particular has seen substantial modification. That has been particularly the situation regarding sustainability. Governments across the world are enacting strict regulations to apply sustainable methods in construction projects. There exists a stronger focus on green building attempts like reaching net zero carbon concrete by 2050 and a higher interest in sustainable building materials. The demand for concrete is anticipated to improve because of populace development and urbanisation, as business leaders such as Amin Nasser an Nadhim Al Nasr would likely attest. Numerous countries now enforce building codes that want a certain percentage of renewable materials to be utilized in construction such as for example timber from sustainably manged forests. Additionally, building codes have included energy-efficient systems and technologies such as green roofs, solar panel systems and LED lighting. Furthermore, the emergence of new construction technologies has enabled the industry to explore revolutionary solutions to enhance sustainability. For example, to lessen energy consumption construction companies are building building with big windows and utilizing energy saving heating, ventilation, and air-con.

Traditional concrete manufacturing employs large stocks of raw materials such as limestone and cement, that are energy-intensive to draw out and produce. Nonetheless, industry experts and business leaders such as Naser Bustami may likely aim out that novel binders such as for example geopolymers and calcium sulfoaluminate cements are good enviromentally friendly options to conventional Portland cement. Geopolymers are formulated by activating industrial by products such as fly ash with alkalis causing concrete with comparable and even superior performance to old-fashioned mixes. CSA cements, on the other hand, need lower temperature processing and give off fewer greenhouse gases during manufacturing. Hence, the adoption of those alternate binders holds great potential for cutting carbon footprint of concrete manufacturing. Also, carbon capture technologies are now being designed. These revolutionary solutions aim to capture co2 (CO2) emissions from concrete plants and use the captured CO2 into the production of artificial limestone. These technology could potentially turn cement as a carbon-neutral as well as carbon-negative product by sequestering CO2 into concrete.

Old-fashioned energy intensive materials like concrete and steel are now being slowly changed by greener alternatives such as bamboo, recycled materials, and manufactured wood. The main sustainability improvement within the building sector though since the 1950s is the inclusion of supplementary cementitious materials such as fly ash, slag and slicia fume. Replacing a percentage of the concrete with SCMs can dramatically reduce CO2 emissions and energy consumption during manufacturing. Additionally, the incorporating of other sustainable materials like recycled aggregates and industrial by products like crushed class and rubber granules has gained increased traction into the previous few decades. The use of such materials has not only lowered the interest in raw materials and natural resources but has recycled waste from landfill sites.
