Abstract
This research deals with assessing fine aggregate (sand) properties as construction materials, that were collected from the Dibdibba Formation at Tar AL-Sayed, Karbala, Iraq, in mortar, concrete, tiles, thermo-stone, solid, hollow masonry blocks and cement paste. Physical tests were carried out on five samples, the moisture content, specific gravity, density of both bulk, dry and porosity were almost varied. The tested samples show that they are unsuitable for all types of concrete, tiles types, thermo-stone and cement masonry block in terms of grain size in all fractions except that of 4.75 mm and 2.36 mm. Later all samples were treated by washing using fresh water, fine clean sand was added in an attempt to form a convenient type for all construction works. The total dissolved solids (1.67– 4.53%), gypsum content (0.64–2.13%), organic matters (0.71 – 2.01%), Cl- (0.11 – 0.81%) and pH (7.51 – 7.91) are ranged within the global standards (ASTM, USCS, BS, and IQS). Quartz is predominated mineral, albite and gypsum are of moderate abundance, whereas mica and calcite occurred as traces.
