Description |
The objective of using sand concrete is to reduce costs especially in sand rich regions where transportation costsof aggregates over long distances makes any construction too expensive. This paper presents the mechanicalcharacteristics of two types of sand concrete, a sand concrete based on rolled sand and dune sand concrete, andcompares these two types of sand concretes. It is also intended to determine the influence of the water/cement(0.4, 0.45, 0.5), cement/ sand (1/3, 1/4) and additives (plasticizers and thinners) on the mechanicalcharacteristics: Compression and tension. It is observed that the cube strength rises with respect to time for thetwo types of sand concrete. The cube strength diminishes when increasing the water/ cement for rolled sandconcrete and increases for the dune sand concrete. The influence of additives is quite noticeable; the rise in thecube strength is about 40 %. Taking into consideration these results, it is then recommended for the users theexploitation of rolled sand concrete with or without additives, however for the dune sand concrete, the use ofadditives is most important.
