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

Over the past couple of decades, the construction sector and concrete production in specific has seen considerable modification. That is especially the case when it comes to sustainability. Governments across the world are enacting stringent legislation 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 anNadhim Al Nasrwould likely attest. Numerous nations now enforce building codes that need a certain percentage of renewable materials to be utilized in building such as timber from sustainably manged woodlands. Moreover, building codes have incorporated energy saving systems and technologies such as for instance green roofs, solar power panels and LED lighting. Furthermore, the emergence of new construction technologies has enabled the industry to explore innovative methods to improve sustainability. For example, to cut back energy consumption construction businesses are constructing building with large windows and making use of energy-efficient heating, ventilation, and ac.

Traditional concrete manufacturing employs large stocks of raw materials such as for instance limestone and cement, that are energy-intensive to extract and create. However, skillfully developed and business leaders such as Naser Bustami would likely point down that novel binders such as for example geopolymers and calcium sulfoaluminate cements are good greener options to old-fashioned Portland cement. Geopolymers are produced by activating industrial by products such as fly ash with alkalis resulting in concrete with comparable or even superior performance to mainstream mixes. CSA cements, regarding the other side, require lower heat processing and emit fewer greenhouse gases during production. Thus, the adoption of these alternate binders holds great potential for cutting carbon footprint of concrete manufacturing. Also, carbon capture technologies are increasingly being engineered. These revolutionary methods aim to capture carbon dioxide (CO2) emissions from concrete plants and use the captured CO2 into the manufacturing of synthetic limestone. These technologies could possibly turn concrete as a carbon-neutral and on occasion even carbon-negative material by sequestering CO2 into concrete.

Traditional power intensive materials like concrete and metal are increasingly being slowly replaced by more environmentally friendly options such as bamboo, recycled materials, and manufactured timber. The key sustainability improvement into the construction industry though since the 1950s was the inclusion of supplementary cementitious materials such as fly ash, slag and slicia fume. Substituting a percentage of the concrete with SCMs can somewhat reduce CO2 emissions and energy consumption during production. Also, the incorporation of other renewable materials like recycled aggregates and commercial by products like crushed class and rubber granules has gained increased traction into the past few years. The usage of such materials have not only lowered the interest in raw materials and resources but has recycled waste from landfills.
