Abstract
This research aimed to develop a light-weight interlocking block using rice husk ash, a waste material from rice husk burning in the production of rock salt. Twelve mixtures with the ratio between cement : dust stone : crushed rice husk ash : uncrushed rice husk ash equaled to 1:6:2:0 1:6:0:2 1:6:1:1 1:5:3:0 1:5:0:3 1:5:1.5:1.5 1:4:4:0 1:4:0:4 1:4:2:2 1:3:5:0 1:3:0:5 1:3 :1.5:1.5 by weight, were compressed into a lump with a dry density of about 1300 kg/m3. The compressive strength at the age of 7, 14 and 28 days and the water absorption at the age of 28 days were tested. The results indicated that when the amount of rice husk ash increased, the compressive strength and the water absorption increased. The compressive strength of the interlocking blocks at the age of 7, 14 and 28 days were in the range of 35 - 71, 43 - 81 and 53 - 109 kg/cm2, respectively. The water absorption at the age of 28 days were in the range of 446 - 546 kg/m3. All ratios of the interlocking blocks had the compressive strength through the standard of TCPS 602/2547, non-load-bearing type. The recommended ratio, which had the lowest cost, is 1:3:0:5.
