A Case Study on Properties of River Sand used in Sundarbazar Municipality in Nepal
Abstract
Concrete is the most important component in construction industry. It consists of cement, fine aggregate, coarse aggregate and water. So, all these materials have great influence on properties of concrete. Fine aggregates combined with cement, acts as a filler in the voids created in the coarse aggregate tostrengthen the concrete. Fine aggregate plays vital role in providing strength to concrete. Properties of concrete is governed by the size,composition and shape of fine aggregate.Fine aggregates come from different sources such as river bed, quarry, etc. Quarry sand possesses good quality and provides good durability and workability of concrete, but the cost of production is high.River sand has rounded or cubic particles with a smooth surface texture that provide good workability in concrete, but it may contains organic materials which will hamper the quality of concrete. So, this study aims to check the
quality of fine aggregates from rivers in Sundarbazar municipality. Overall observation and analysisconcludes that sand sample from Marsyangdi river meets the standard value of these physical properties whereas sand sample from Paundi river deviates from the standard value of these physical properties. Classification on grading zone, Marsyangdi river sand can be used for concreting as well as plastering in structural construction works. Similarly, Paundi river sand can be used in road construction since its finer size helps to bind coarser particles in gravelling.
