| description | It is widely use of air-conditioning
systems in Thailand due to its location. It is located in a tropical zone with
relatively high temperatures all year round, with high humidity and high
intensity of sunlight. In order to save electrical energy for air-conditioning
systems, preventing heat transfer into the building is required. The objective
of this study is to investigate the physical and thermal properties of concrete
blocks. An attempt is made to increase heat resistance of concrete blocks. Foam
beads (0-0.30% by weight) and kaolin (0-70% by weight) were added in concrete block
mixture to increase discontinuous voids in concrete. Compressive strength and
water absorption of concrete blocks were tested. The testing results indicated
that compressive strength decreased when foam beads and kaolin were added.
Water absorption increased when foam beads were added. In contrast, the more
kaolin added the less water absorption. The thermal conductivity coefficient of
concrete blocks was also investigated. The results confirmed that the higher
the amount of foam beads or kaolin added, the higher the thermal resistance of
concrete blocks. Thermal time-lag behavior was also investigated. The results
indicated that concrete block with kaolin took the longest time in heating and
took the shortest time in cooling. These properties are good for heat
prevention in hot climate regions. These concrete blocks which were developed
and tested in this research conform to the Thai Industrial Standard. Finally,
it can be concluded that because of its thermal behavior, concrete block with
kaolin is a suitable energy-saving concrete block for hot and humid climates. |
