"partial replacement of fine aggregate with saw dust for light weight and insulating concrete". In this present experimental work, we incorporate the saw dust with concrete in order to replace the fine aggregates that can be used in the building construction. By adding the sawdust it is not only the fine aggregates content we replace, it ...

2. Materials and methods. LWA having a unit weight of 1536 kg/m 3 and limestone crushed aggregate having a maximum size of 19 mm, procured from a local aggregate crushing facility were used as LWA and NWA, respectively. Locally produced crushed stone sand having fineness modulus of 4.18 was used as fine aggregate.

Fine Aggregate Meaning. Fine aggregates are usually sand or crushed stone that are less than 9.55mm in diameter. Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete. Larger aggregate diameters reduce the quantity of cement and water needed.

Figure 1 shows the grain size distribution curves for the blended fine aggregates containing granite dust replacing 0, 10, 15, 20 and 30% by volume of sand. It can be observed from the figure that the blended fine aggregate exhibits well-graded curve which means it may be suitable for the preparation of concrete.
