This study investigates the use of sodium silicate as surface modifier for coir dust waste in cement composite. The improvement of interfacial bond between the lignocellulosic coir dust material and cement matrix could increase potential application of coir dust waste in civil industry, an added value and a solution to its disposal problem. A coir dust-cement composite was produced using a ratio of 1:.0.11:0.75 by weight of cement (cement: coir dust: water). The specimen sizes of 50mmx50mmx100mm for compression and 50mmx50mmx250mm for modulus of rupture were prepared in triplicate and tested using Universal testing machine. Sodium silicate significantly improved compressive and flexural strength and effectively reduced sorption properties of the coir dust cement composite. Based on the mechanical properties test, produced composite was suitable for light weight construction material.
