Properties of Cement Matrix According to Replacement Ratio of Bamboo Activated Carbon
Recently, China's air pollution is serious because of China's fine dust. Fine dust is a first-class carcinogen and plans are needed to reduce it. Therefore, in this study, an experiment was conducted to investigate the adsorption properties of the fine dust of the matrix by producing a matrix incorporating bamboo activated carbon. Cement and bamboo activated carbon are used as materials used, and in the case of bamboo activated carbon, harmful substances can be adsorbed. The replacement ratio of bamboo activated carbon was 0% to 40% in 10% increments, and experiments on absorption rate, density, fluidity, strength, and fine dust adsorption performance were performed. After inserting the measuring device and the air circulation device, the measurement was performed for 24 hours in 1 hour increments. As the replacement rate of bamboo activated carbon increases, the strength tends to decrease gradually. The reason is that bamboo activated carbon has a lower strength than cement, so it decreases. The absorption rate is gradually increasing as the replacement rate increases. This is because bamboo activated carbon has a property of absorbing moisture and gradually increases as the replacement rate increases. Density and table flow tend to decrease gradually as the replacement rate increases. In terms of density, bamboo activated carbon is thought to decrease gradually due to its low density. In the case of table flow, bamboo activated carbon absorbs moisture, so it gradually decreases by absorbing the moisture required for the flow. Fine dust concentrations tend to gradually decrease as the replacement rate of bamboo activated carbon increases. The reason for this is considered to be gradually reduced by the nature of adsorbing fine dust of bamboo activated carbon. The strength is lower than that of a regular finishing board, so improving it can help improve indoor air quality.
