The Characteristiks Of Bricks In West Sumatera

[Full Text]

Brick, Density, Water Absorption, Brick Compression strength



The majority of earthquake victims were caused by building debris. The latest research after earthquake in Padang city found that there were many victims fell due to the collapse of the brick wall. Other research states that bricks in Sumatera Barat was not in Indonesian standard or Indonesian National Standards or SNI 15-2094-2000. This is the reason to study the characteristics of bricks in Sumatera Barat. This associative research collected bricks in Sumatera Barat randomly. In each place, brick samples were taken when people or worker building a houses. It was found that the average Sumatera Barat bricks had a higher density than the standard, which was 1.39 gr/cm² or above SNI 1.2 gr/cm2, and the highest was found from Pesisir Selatan 1, 44 gr/cm². All dimensions are below the minimum standard, the average length of 18.17 cm, width 8.88 cm, height 4.64 cm, while according to the standard the length is 23 cm, width 11 cm, and height 5.5 cm. For the brick water absorption test found an average of 26.21%, which exceeds the maximum standard of only 20%. Furthermore, the average compressive strength was found to be 43.04 kg/cm², meaning that it was below the SNI standard of 50 kg/cm2. No dimensional, density and water absorption effects were found on the compressive strength of bricks, with an average influence value ˂0.4. This finding is important as a basis for the need to improve the characteristics of bricks in Sumatera Barat, so that they are more better and friendly to earthquakes to be used in Sumatera Barat.
