Alternatives For Sand As Fine Aggregate. Abstract There is a great demand of both coarse fine aggregates for the construction of infrastructural facilities, rather than using a conventional river sand as a fine aggregate in concrete mix as one of the construction material which has led to the scarcity of the material an alternative material ... Fine Aggregate Fine aggregate/ coarse sand consists of natural sand, crushed stone sand or crushed gravel stone dust. It should be hard, durable chemically inert, clean and free from organic matter, not containing any appreciable amount of clay balls or pellets and other harmful impurities i. e. alkaline, salt, mica, decayed vegetation, lumps etc.

Two sets of mixture with six samples of each for a total of 12 samples were prepared and tested. Findings of the study revealed that the concrete mixture using sawdust is comparable to the compressive strength of concrete mixture using sand as fine aggregate. Thus, the sawdust can be considered as an alternative for sand as fine aggregate. Jul 30, 2018 This study is experiment the suitability to use beach/sea sand as a substitute for river sand as fine aggregate for concrete. Experimental results show that the washed sea sand is ideal for concrete and plastering activities. REFERENCE. National sand study for Sri Lanka, vols. 1 and 2.
