A Systematic Review Of Drivers And Barriers To The Assimilation Of Net-Zero Carbon Emission Requirements Into Construction Megaprojects Procurement, Andrew Anafo, Robert Osei-Kyei, Vivian Wy Tam

CIB Conferences

There is no gainsaying that climate change is globally recognised as the greatest environmental threat of the 21^st century. Therefore, under the Parish Agreement to restraint greenhouse gases (GHGs) emission to net-zero by 2050, climate change mitigation is at the core of environmental schemes of governments worldwide. Bearing in mind that mega construction projects contribute to the rising level of GHGs in the atmosphere, and the seldom consideration of net-zero carbon requirements in the procurement of construction megaprojects, this paper examines the drivers and barriers to assimilating net-zero requirements into construction megaprojects procurement. When net-zero emission requirements are well-thought-out …

Using Recycled Materials For Asphalt Road Pavement Pothole Repair To Reduce Carbon In Construction, Kenneth O. Lawani, Carys Morrison, Farhad Sadeghineko, Billy Hare, Michael K. Tong

CIB Conferences

The physical condition of motorways and trunk roads in Scotland is monitored by specialist contractors on behalf of Transport Scotland by annual condition survey to provide information about the structural, surface and safety condition of the road surface or pavements. Flexible asphalt pavement is subjected to continuous vehicular and environmental loading causing potholes that needs to be reinstated to maintain functional requirements. However, traditional pothole repair materials have sustainability concerns and can deteriorate quickly after installation. The longevity and durability of pothole repairs is important as repeat treatments incite additional costs. Innovation can enhance sustainable development and for road transport …

Performance Of Natural Pozzolans (Nps) In Field Concrete Mixtures, Bibigul Zhaksybay, Alberto Castillo, Raikhan Tokpatayeva, Jan Olek

CIB Conferences

Cement, the binding component of concrete, the most widely used construction material in the world, accounts for 8% of global CO₂ emissions. Its significant contribution to global warming has motivated researchers to aim for achieving carbon neutrality by 2050, in alignment with the 1.5°C global warming temperature limit stipulated by the Paris Agreement. A successful strategy to reduce CO₂ emissions in concrete production is through the use of supplementary cementitious materials (SCMs) as a partial replacement for cement. However, it is estimated that by 2030, the demand for the most common SCM, fly ash, will exceed its supply. …
