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

Traditional concrete manufacturing utilises large reserves of raw materials such as limestone and cement, which are energy-intensive to draw out and create. However, industry experts and business leaders such as Naser Bustami would likely point out that novel binders such as geopolymers and calcium sulfoaluminate cements are good greener alternatives to traditional Portland cement. Geopolymers are built by activating industrial by products such as fly ash with alkalis resulting in concrete with comparable as well as superior performance to mainstream mixes. CSA cements, in the other hand, require lower heat processing and give off less carbon dioxide during manufacturing. Therefore, the adoption of those alternative binders holds great possibility of cutting carbon footprint of concrete manufacturing. Additionally, carbon capture technologies are increasingly being developed. These revolutionary solutions make an effort to capture carbon dioxide (CO2) emissions from concrete plants and make use of the captured CO2 within the production of artificial limestone. This technology may potentially turn concrete in to a carbon-neutral and on occasion even carbon-negative material by sequestering CO2 into concrete.

Over the past number of years, the construction industry and concrete production in specific has seen considerable change. Which has been especially the case in terms of sustainability. Governments around the globe are enacting stringent legislation to implement sustainable practices in construction ventures. There is a more powerful focus on green building efforts like reaching net zero carbon concrete by 2050 and a greater demand for sustainable building materials. The interest in concrete is expected to boost because of population development and urbanisation, as business leaders such as Amin Nasser anNadhim Al Nasrwould likely attest. Numerous countries now enforce building codes that need 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 for example green roofs, solar panels and LED lights. Also, the emergence of the latest construction technologies has enabled the industry to explore innovative methods to improve sustainability. For example, to lessen energy consumption construction companies are building building with large windows and utilizing energy-efficient heating, air flow, and ac.

Old-fashioned energy intensive materials like tangible and steel are now being gradually changed by greener options such as bamboo, recycled materials, and manufactured wood. The primary sustainability enhancement within the building industry however since the 1950s has been the introduction of supplementary cementitious materials such as fly ash, slag and slicia fume. Substituting a portion of the concrete with SCMs can dramatically reduce CO2 emissions and energy consumption during manufacturing. Moreover, the incorporating of other sustainable materials like recycled aggregates and commercial by products like crushed class and plastic granules has gained increased traction in the previous few decades. Making use of such materials has not only lowered the interest in raw materials and resources but has recycled waste from landfills.
