AB  - Despite the abundance of sand mining sites observed in Cameroon and especially in the Western region, the recognition of the granular properties of these building materials remains a major issue for local builders. This study focuses on the characterization of granular properties of Nepenet sand. On-site sand samples were subjected to laboratory tests to determine their granular properties. Analysis results show that sands are clay (SE≈65<70%) and medium sized (2.5<Mf≈3.175<3.5). Washing makes sand coarse by loss of these fine elements (Mf>3.6<3.5%) with negligible improvement in their cleanliness (SE≈70%). These natural sands are therefore not recommended for concretes. However, treatment by mechanical washing can make them suitable for concrete of good resistance to the detriment of the ease of implementation. Thus, the improvement of the quality of the sand lies in the installation of a washing device in order to make these materials cleaner.

Abstract

Despite the abundance of sand mining sites observed in Cameroon and especially in the Western region, the recognition of the granular properties of these building materials remains a major issue for local builders. This study focuses on the characterization of granular properties of Nepenet sand. On-site sand samples were subjected to laboratory tests to determine their granular properties. Analysis results show that sands are clay (SE≈65<70%) and medium sized (2.53.6<3.5%) with negligible improvement in their cleanliness (SE≈70%). These natural sands are therefore not recommended for concretes. However, treatment by mechanical washing can make them suitable for concrete of good resistance to the detriment of the ease of implementation. Thus, the improvement of the quality of the sand lies in the installation of a washing device in order to make these materials cleaner.

Author Keywords: Sand, Cameroon, granular characterization, washing, treatment.

Abstract: (french)

Malgré l’abondance des sites d’extraction de sable observés au Cameroun et particulièrement dans la région de l’Ouest, la reconnaissance des propriétés granulaires de ces matériaux de construction reste un enjeu majeur des bâtisseurs locaux. Cette étude porte sur la caractérisation des propriétés granulaires du sable de Népenet. Des échantillons de sable prélevés sur le site ont subi des essais de laboratoire pour la détermination de leurs propriétés granulaires. Les résultats des analyses montrent que les sables sont argileux (ES≈65<70%) et de granulométrie moyenne (2,53,6<3,5%) avec une amélioration négligeable de leur propreté (ES≈70%). Ces sables à l’état naturel ne sont donc pas recommandés pour les bétons. Néanmoins un traitement par lavage mécanique peut les rendre adapté au béton de bonne résistance au détriment de la facilite de mise en œuvre. Ainsi l’amélioration de la qualité dudit sable réside en la mise en place d’un dispositif de lavage permettant de rendre ces matériaux plus propres.
