This paper focused on the use of cassava starch as an additive in burnt earth bricks. Burnt earth bricks is one of the oldest building materials in use and abundantly found everywhere with affordable and reasonable cost. With regard to the availability of cassava in most part of the country, looking into the possibility of using cassava starch as an additive for burnt earth bricks production is of great importance in other to enhance their physical property, such as water absorption, abrasion resistance and compressive strength. Cassava starch content of 0%, 4%, 6%, 10% and 12% were used in the mix. Batching mix by volume was adopted to get the quantity of material to be use. The specimens were produced in 100mm cube mould, demoulded after 24 hours and air dry for 28 days of curing before burning in an electric furnace at a temperature of 1000oC for a period of two hours. The result gotten from the research show that water absorption of burnt earth bricks was drastically reduced with the incorporation of cassava starch in the mix. Abrasion resistance and compressive strength of the earth burnt bricks were increased from 4.09cm2/g to 27cm2/g and from 1.19N/mm2 to 2.19N/mm2 respectively at cassava starch content of 6%. Satisfactory performance of the earth burnt bricks was achieved at an optimum amount of 6% of cassava starch content and is thus recommended for incorporation as an additive in producing earth burnt bricks.
