ABSTRACT: The paper evaluates
the feasibility of reducing clinker in the Portland Cement production using
local metakaolin in Burkina Faso. Standardized testing methods have been used
for this purpose, and experiments were performed on mortar prisms containing
different amounts of metakaolin. Important results about the physical,
mechanical and durability characterization of blended mortars were carried out
in this study. The obtained results are discussed based on available literature
data. These results have shown increased physical and durability properties for
blended mortars. Although the mechanical strengths remained relatively low for
higher MK incorporations, the latter grow to surpass these of PC mortars (the
reference) at 28, 56 and 90 days of curing. The results in the paper, have
confirmed the possibility of using metakaolin to partially substitute cement, a
possibility to reduce the CO2 production by the cement industry in Burkina
Faso.
