ABSTRACT

Modern day building materials must be sustainable, cheap, environmental friendly, durable and available. Laterite reinforced with bamboo fiber was moulded into blocks to determine the compressive strength, flexural strength and fracture toughness using universal tensile machine (UTM), while the elemental composition was determined by EDS, SEM/Gwyddion software were used to study the fractured surface of the bamboo-fiber reinforced laterite (BFRL) block. Water absorption test and bulk density were also carried out. The blocks were moulded by varying the percent weight (%wt) fraction of bamboo fiber from 0 to 25%. The dimensions for the compressive and flexural samples were 100 x 100 x 100 mm and 600 x 100 x 100 mm respectively. The results of the experiment showed that at 25 %wt of bamboo fiber a maximum compressive strength, flexural strength and fracture toughness of 5.0卤0.25 MPa, 2.25卤0.113 MPa and 1.70卤0.085 MPa respectively were obtained. EDS result reviewed the following elements Al, Si, Ca, Fe and C. SEM images analyzed using Gwyddion software reviewed different fracture patterns.
