Paper Title:A Review on the Application of Carbon Dioxide Gas as a Curing Compound


The rising level of carbon dioxide in the atmosphere is one of the main concerns of researchers of all the time. The high level of CO2 concentration in the atmosphere has serious effects on environment as it can make the earth warmer than it would be. Recently, there was a warning from UN weather agency’s annual flagship report about the increasing level of CO2 concentration in the atmosphere. According to the report, the CO2 concentration has risen from 400 parts per million in 2015 to 403.3 parts per million in 2016, which was found to be the highest rate in past three million years. This paper discusses about reduction of CO2 emission by utilizing it in the curing process of precast concrete elements. The comparison of effect of different curing conditions on carbonation reaction was reviewed. The effect of initial curing in the water loss and carbon uptake of concrete was also discussed.
