Abstract

As humans began to use fossil energy such as coal and oil through the Industrial Revolution two centuries ago, the amount of CO2 emitted into the atmosphere began to increase rapidly. One of the main causes of CO2 is the construction industry, and research to solve it is being actively conducted. Accordingly, in this study, a permeable block mixed with photosynthetic cyanobacteria was manufactured and the flexural strength, compressive strength, permeability coefficient, and CO2 adsorption performance were analyzed. As a result of the experiment, as the mixing ratio of the cyanobacteria culture solution increased, the flexural and compressive strength of the cement matrix decreased, but the CO2 adsorption performance increased. In the case of aggregate mixing, as the mixing ratio increased, the flexural and compressive strength decreased, but the CO2 adsorption performance and permeability increased.
