PERFORMANCE OF BITUMEN BOUND MASONRYBLOCK INCORPORATING WASTE MATERIALS

Abstract

Continuous efforts are needed in utilizing waste materials in building
industry. This investigation was intended to use waste materials, namely: steel slag,
crushed glass and coal fly ash for producing Masonryblock, i.e. a masonry building
block bound with bitumen (asphalt). The binder used was bitumen of 50 pen. The
materials were pre-heated at 160 °C for 3 hours before mixing and compacted
using static compactor at 8 MPa. The properties of the blocks evaluated were
compressive strength and creep. In order to minimize creep deformation, the
samples were heat cured at 160 °C for 24, 48, and 72 hours. Creep test was carried
out by loading the samples using a cantilever arm loading equipment with 1 MPa
stress until the creep strain stable. The strain was measured by means of a 50 mm
Demec gauge. It was found that the Masonryblock compressive strength
comparable to the concrete block commonly used in the United Kingdom (UK).
The sample requires at least 48 hours curing in order to satisfy creep performance
requirement.
