Abstract: | A height development in the construction sector has knower at Algeria during this last decade. However, the construction has usually confronted to two contradictory factors: reducing the coast and improving the quality. The availability of local materials like, the dune sand, who covers more than 60% of Algeria aria, can offer a good valorization in the construction sectors. Sand dune plays a very important role in the manufacture of concrete, but most researchers have found that this material has some disadvantages such as large shrinkage. The experience of most authors found that the addition of fibers to concrete and the substitution of a part of sand dune by river sad can reduced the shrinkage, increased the compression and tension resistance, and can also improve others proprieties like, porosity, ultrasonic velocity. |
