Concrete production is major factor to CO2 emissions, but there is a desire for greener alternatives.

Conventional power intensive materials like concrete and steel are increasingly being slowly changed by more environmentally friendly alternatives such as bamboo, recycled materials, and engineered wood. The key sustainability enhancement in the construction industry though since the 1950s was the introduction of supplementary cementitious materials such as fly ash, slag and slicia fume. Substituting a portion of the cement 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 within the previous couple of years. Making use of such materials has not only lowered the demand for raw materials and resources but has recycled waste from landfill sites.

Within the last couple of decades, the construction industry and concrete production in particular has seen substantial modification. That is especially the case with regards to sustainability. Governments around the world are enacting strict legislations to apply sustainable practices in construction projects. There is a stronger attention on green building efforts like reaching net zero carbon concrete by 2050 and a higher demand for sustainable building materials. The interest in concrete is anticipated to boost as a result of populace development and urbanisation, as business leaders such as Amin Nasser an Nadhim Al Nasr would likely attest. Many nations now enforce building codes that want a certain portion of renewable materials to be utilized in construction such as timber from sustainably manged forests. Furthermore, building codes have included energy efficient systems and technologies such as for example green roofs, solar panels and LED lights. Furthermore, the emergence of the latest construction technologies has enabled the industry to explore revolutionary solutions to improve sustainability. For example, to reduce energy consumption construction businesses are constructing building with large windows and using energy-efficient heating, ventilation, and air-con.

Conventional concrete manufacturing employs huge stocks of raw materials such as for instance limestone and concrete, which are energy-intensive to extract and produce. Nevertheless, industry experts and business leaders such as Naser Bustami would likely point out that novel binders such as for example geopolymers and calcium sulfoaluminate cements are excellent enviromentally friendly options to old-fashioned Portland cement. Geopolymers are formulated by triggering industrial by products such as fly ash with alkalis causing concrete with comparable and on occasion even superior performance to conventional mixes. CSA cements, regarding the other side, need lower temperature processing and emit less carbon dioxide during manufacturing. Thus, the adoption among these alternate binders holds great prospect of cutting carbon footprint of concrete manufacturing. Also, carbon capture technologies are increasingly being designed. These innovative approaches make an effort to catch carbon dioxide (CO2) emissions from cement plants and make use of the captured CO2 within the production of synthetic limestone. These technology could possibly turn cement right into a carbon-neutral and even carbon-negative material by sequestering CO2 into concrete.
