||This paper aims at exploring the sites of raw materials used in the
production of laterite briquettes in Benin Republic. Specifically, the
work was based on the investigation, delimitation and evaluation of the
reserves of lateritic soils and alterites that may be included in the
production of laterite briquettes.
The tests showed thirty-three (33) favorable sites among which
eighteen (18) lateritic soils and fifteen (15) alterites identified in the
twelve Benin departments on the plateaux of the coastal sedimentary
basin (lateritic soils) as well as on the crystalline bedrock, the Buem
and the sedimentary basin (alterite) of Kandi. The various sections of
wells obtained revealed a homogeneity on the sites of lateritic soils.
Moreover, they appear as coherent soils while alterites present a more
or less indurate appearance.
The bedrock profiles varied between 1.2 and 2.2m comparatively to
plateaux where the depths of the wells reached more than 5m. The
established reserves are estimated to be 10 410 949m 3 for lateritic soils
and 724 806 m 3 for alterites; which represents a great asset with regard
to the high price of usual construction materials and the environmental
challenge. Thus, local materials impose themselves day by day.
