Utilization of vesicular basalt fragment as aggregate in cement board for knockdown building wall
MetadataShow full item record
This research aims to develop the cement board from vesicular basalt fragment which reinforced with steel wire mesh. The ratio of Portland cement type1: fine sand: vesicular basalt fragment: sodium silicate: tap water was equal to 1: 2: 4: 0.03: 0.55 by weight. The 5 sizes of steel wire mesh (steel wire no.25) were installed including: 3/8”, 1/2”, 5/8”, 3/4”, and 1”. The cement boards were produced by compression machine. The property tests of cement-bonded fiberboard followed the TIS. 878-1994 standard (cement bonded particle board: high density). From the results, the 3/4" of steel wire mesh size was the most suitable size for reinforcing the cement board from vesicular basalt fragment. This developed cement boards was the construction materials which had the high bending strength, good thermal insulation, and moisture protection properties.
