Development of a Mixture of Lightweight Cell Crete with Hydraulic Cement for Green Roof Construction in Thailand

Abstract

Green roofs are still not widely known in Thailand. It is caused by the complicated construction process, the need of imported materials, and the higher cost compared to conventional roofs. Green roofs are considered a new alternative due to their ability to reduce power usage, noise, air pollution. develop an urban ecosystem, and so on. Thus, the researcher is interested in using lightweight cell crete (LCC) as a load structural material to support the weight of the soil used to grow plants, since the lightweight cell crete has the following properties: strength, resistance to heat, waterproofness, soundproofness, and light weight. Moreover, the construction cost will be more affordable. The purpose of this study is to determine lightweight cell crete for applying on green roof. The density of lightweight cell crete is set range 600 – 1,800 kg/m³. The result found that the properties of lightweight cell crete 1,200 and 1,400 kg/m3 meets the standard to substitute the normal concrete. In addition, the researcher put the green roof with lightweight cell crete structure to the test in actual site and found that it can contribute to the increase of green space in urban
life. The cost of construction was reduced, as was the temperature inside the building. It is advantageous for Thailand's green roo industry.
