As populations continue steadily to grow and towns expand, the interest in concrete increase.

Over the past number of years, the construction sector and concrete production in particular has seen important change. That has been particularly the situation with regards to sustainability. Governments around the globe are enacting stringent legislations to apply sustainable methods in construction projects. There is a more powerful attention on green building efforts like reaching net zero carbon concrete by 2050 and a higher interest in sustainable building materials. The interest in concrete is expected to increase as a result of populace growth and urbanisation, as business leaders such as Amin Nasser an Nadhim Al Nasr would likely attest. Numerous nations now enforce building codes that need a certain percentage of renewable materials to be utilized in construction such as timber from sustainably manged woodlands. Moreover, building codes have included energy-efficient systems and technologies such as green roofs, solar panel systems and LED lights. Additionally, the emergence of the latest construction technologies has enabled the industry to explore revolutionary solutions to enhance sustainability. For instance, to reduce energy consumption construction businesses are constructing building with big windows and making use of energy conserving heating, ventilation, and air-con.

Traditional concrete manufacturing employs huge reserves of raw materials such as for example limestone and cement, that are energy-intensive to extract and create. Nonetheless, industry experts and business leaders such as Naser Bustami would probably point down that novel binders such as for instance geopolymers and calcium sulfoaluminate cements are excellent enviromentally friendly alternatives to conventional Portland cement. Geopolymers are built by triggering industrial by products such as fly ash with alkalis resulting in concrete with comparable or even superior performance to old-fashioned mixes. CSA cements, on the other side, require reduced temperature processing and give off fewer greenhouse gases during manufacturing. Therefore, the use of those alternate binders holds great possibility of cutting carbon footprint of concrete manufacturing. Furthermore, carbon capture technologies are increasingly being introduced. These innovative solutions try to catch carbon dioxide (CO2) emissions from cement plants and make use of the captured CO2 in the manufacturing of synthetic limestone. This technologies could possibly turn cement right into a carbon-neutral and sometimes even carbon-negative material by sequestering CO2 into concrete.

Old-fashioned energy intensive materials like concrete and metal are increasingly being gradually changed by greener alternatives such as for instance bamboo, recycled materials, and engineered timber. The key sustainability improvement in the construction sector however since the 1950s is the introduction of supplementary cementitious materials such as fly ash, slag and slicia fume. Replacing a portion of the concrete with SCMs can somewhat reduce CO2 emissions and energy consumption during production. Also, 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 past few years. The application of such materials have not only lowered the interest in raw materials and resources but has recycled waste from landfills.
