RESULTS AND DISCUSSION. Nevertheless, table 1 and 2 reveal that the particles of the samples are uniformly graded. There are 90.8% and 83.8% of sand size particles in the river sharp sand and quarry dust samples respectively. The quarry dust sample contains 11.8% of silt/dust size particles and 4.4% of gravel size particle, while the river ...
The sand is used extensively for horse arenas, under water tanks and fuel tanks and has been used for all the above purposes for the last 40 years. It is trucked as far as Sydney.

River sand concrete attained higher densities than quarry dust concrete for all ages of curing. The higher density of river sand concrete can be as a result of higher density of the river sand in relation to the quarry dust. The density of river sand concrete and quarry dust concrete are within the nominal value of 24 kN/m 3 (i.e. 2,446 kg/m 3
