Abstract
Clay is a raw material that has many uses across the different industries around the world.The principal use of clay in some part of Nigeria are: pots making, ornamental decoration and ceramics etc. The study examine engineering properties of sawdust modified clay soil and to determine thegeotechnical properties of these materials be established to define the suitability of sawdust modified clay soil for engineeringpurposes. Test such as: porosity, permeability, atterberg limit, cold compressive strength, impact strength, unconfined compressive strength and absorption test. The clay samples were collected from Ondo state,Niger state, Ekiti state and Lagosstate respectively in Nigeria. It was cleaned, soaked, dried, crushed and sieved then moulded to some definite shapes such as cylindrical and rectangular shape depending on the type of test carried out on the various clay samples.0%, 45%,50% and 60%percentages of sawdust were varied with the clay sample and moulded.. Results obtained shows that natural water content are fairly okay which varied between2.34% and 3.5% . The atterbag limit classified soil as MH, ML,CL and ML for for all the location respectively according [21]. The permeability test shows that all the sample are within the range of semi pervious clay material according to USBR specification. The effect of sawdust on the clay materials as shown in figure 1,2 and 3 shows that the modified clay has a lower strength, a higher water absorption and a higher porosity as the sawdust content in the clay sample increases and vice versa, this is due to effect of pores created by sawdust. Results obtained show that Lagos has the highest water retention potential compare to other locationand has the lowest rate of water absorption, highest resistance to shattering which make the sample the strongest in term of compressive strength and also very suitable as a filter media for industrial application.

Keywords: porosity, permeability, compressive strength, impact test, water absorption test
