Abstract
This paper discusses earth as a building material and the extent to which earth building
technology has evolved over the years. In particular it addresses the adobe, compressed and
rammed earth techniques of earth building as suitable techniques for Liberia consumption. In
addition, the paper investigates the suitability of the Latosols soils of Liberia for earth building
construction purposes using standardized earth building principles and requirements. A local
Johnson City, Tennessee, earth sample found to have the same physical characteristics of the
Latosols of Liberia was used to simulate Liberia soils to produce specimen blocks at different
configurations of moisture content and stabilizers (Bentonite and cement). Following 14 days of
cure, the blocks were tested for compressive strength. It was found that blocks produced from the
natural soil with no stabilizer added were structurally adequate for building construction
purposes. A cost-benefit analysis involving blocks with and without stabilizer (cement) added
was also performed.
