Effect of Sand Fines and Water/Cement Ratio on Concrete

surface-dry samples measured were 2.60 and 2.61 for fine and coarse aggregates respectively. This indicates the aggregates used for the study were within the accepted specified values for concrete production in accordance with BS EN 1097-6 [19]. The water absorption for the sand used was 1.4% which is below the specification limit of 2%.

Mechanical and Durability Properties of Concrete Made with

River sand is one of the main ingredients used as a fine aggregate in concrete production. A rising demand for construction material has led to the overexploitation of river sand, and this overexploitation has led to harmful consequences like increase in river bed depth, lowering of the water table, and intrusion of salinity into the river.

The Suitability Of Limestone Aggregates For Use In

Crushing Limestone to produce fine aggregate results in the generation of a substantial amount of fine sizes (minus 0.075mm or #200 mesh) commonly referred to as dust. These fines do not aid in the production of good quality concrete and therefore must be removed from the sand before combining with Coarse Aggregate and cement.

Practical Grading of Aggregates Concrete Technology

The suitability of the fine sand of zone 4 for use in reinforced concrete should be tested. For sands, the sand content of the mix should be low whose greater part is smaller than 60C micron. In general, finer the grading of the fine aggregate, higher should be the coarse/fine aggregate ratio. Typical values are shown in Table 4.23.
