RESEARCH ON THE REDUCTION OF CARBON EMISSIONS IN BUILDINGS BY SPECIFYING LOW-CARBON CONCRETE MIXES IN CHINA

Abstract

Buildings are key contributors to the emissions of toxic carbon dioxide, which is a global greenhouse gas, and lowering the concentration of this gas is an essential mitigation in mitigating the effects of climate change. This study majorly focused on the strategies that could be applied in the building and construction industry to help in lowering carbon concrete in concrete mixes. Various challenges were reported to be prevailing when it comes to the adoption of the use of low-carbon concrete in the construction sector. The cost of low-carbon concrete alternatives was among the topmost challenges that made most of the owners of the construction projects apply them. The study was conducted at Huajie Construction Company, which was among the leading construction companies in China. This facilitated the acquisition of accurate information as per the needs of the research objectives. For data collection, 150 participants were selected from this company through the implementation of a purposive sampling technique. Therefore, to address all these, some low-carbon concrete alternatives were suggested for adoption in construction activities. These alternatives included: carbon capture concrete, hempcrete, ferrock, recycled aggregate concrete, and geopolymer concrete. All these alternatives had safe properties that could help to lower carbon emissions.
