The building and construction sector has gone via a remarkable change since the 1950s.

Over the past handful of years, the construction sector and concrete production in specific has seen significant change. That has been especially the case with regards to sustainability. Governments around the world are enacting strict legislation to apply sustainable techniques in construction projects. There exists a more powerful attention on green building efforts like reaching net zero carbon concrete by 2050 and an increased interest in sustainable building materials. The interest in concrete is expected to boost due to population development and urbanisation, as business leaders such as Amin Nasser anNadhim Al Nasrwould probably attest. Numerous nations now enforce building codes that need a certain percentage of renewable materials to be utilized in construction such as for instance timber from sustainably manged forests. Moreover, building codes have included energy saving systems and technologies such as for instance green roofs, solar power panels and LED lights. Furthermore, the emergence of the latest construction technologies has enabled the industry to explore revolutionary solutions to enhance sustainability. For example, to reduce energy consumption construction companies are building building with big windows and utilizing energy conserving heating, ventilation, and air conditioning.

Traditional concrete manufacturing employs huge reserves of raw materials such as for instance limestone and cement, which are energy-intensive to draw out and create. Nonetheless, skillfully developed and business leaders such as Naser Bustami may likely point down that novel binders such as for example geopolymers and calcium sulfoaluminate cements are good enviromentally friendly options to conventional Portland cement. Geopolymers are built by activating industrial by products such as fly ash with alkalis causing concrete with comparable and sometimes even superior performance to old-fashioned mixes. CSA cements, in the other hand, need lower temperature processing and give off fewer greenhouse gases during manufacturing. Thus, the use of those alternative binders holds great possibility cutting carbon footprint of concrete manufacturing. Furthermore, carbon capture technologies are increasingly being improved. These innovative techniques aim to catch carbon dioxide (CO2) emissions from concrete plants and use the captured CO2 in the manufacturing of synthetic limestone. This technologies could potentially turn cement into a carbon-neutral and even carbon-negative product by sequestering CO2 into concrete.

Conventional energy intensive materials like tangible and metal are increasingly being slowly replaced by greener alternatives such as bamboo, recycled materials, and manufactured wood. The key sustainability improvement within the construction sector though since the 1950s happens to be the introduction 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. Moreover, the incorporation of other renewable materials like recycled aggregates and industrial by products like crushed class and rubber granules has gained increased traction into the past few decades. Making use of such materials has not only lowered the interest in raw materials and natural resources but has recycled waste from landfill sites.
