In this paper, sawdust concrete with nominal mixes 1:1:2, 1:1½:3, 1:2:4, 1:3:6 and 1:4:8 were subjected to durability test. The 28-day water absorption of the mixes are 5.69, 8.97, 8.29, 7.83 and 11.11%, 28-day linear shrinkages are 0.67, 0.50, 1.83, 1.83 and 1.95%, respectively. The 28-day thermal conductivities are 0.229, 0.232, 0.229, 0.223 and 0.176W/m.K., respectively. The 28-day compressive strengths of mixes 1:1:2 and 1:1½:3 are 18.33 and 8.78 N/mm2, respectively, while their 28-day flexural strengths are 1.71 and 1.33 N/mm2, respectively. These values indicated that they are good and durable concrete and can be used for construction of rigid pavement.
