Abstract:
This study focuses on evaluating the use of the Dangote Ordinary Portland and Portland
Pozolana cement for structural concrete production and its production processes of Dangote
cement factory with special emphasis to its property as ingredient of structural concrete with
regards to quality, eniviroment and minimization of structural cross sections However, most
of the consultants who design structures are simply specifying the ingredients of concrete
without enough description of type, reasonable content, and relations with other factors
which have direct effect to the hydrolysis reaction of the cements. This and others are costing
the country negatively.
Anon-experimental survey and experimental test design employing a qualitative approach
was used in in this investigation. The research Design in this Current inquiry involved two
phases: data Collection and data analysis. The data Collection phase included examining the
current literature to identify relevant background and collecting data from the factory. The
data analysis phase distilled the findings of the laboratory test result of different classes of
Concrete produced from each of cement type were Conducted and recorded at different ages.
This research discuses results from analysis on the compressive strength test results and rate
of gaining strength.by studying how each of the classes of Concrete produced by Ordinary
Port land and Portland Pozolana Cement were compared, we found good strength
development was observed especially in the high strength concrete, Strength up to54.75%
and 58.06% in 3 days and 77.74% and 73.7% in 7 days relative to their28 days strength was
possible using the Dangote Portland Pozolana Cements and Ordinary Port land Cement
respectively.
Further, we identifies that the OPC is best in high early Strength concrete production. And
the PPC cannot produce a 28th day concrete compressive strength as high as that of the
OPC .The study also identifies that carbon dioxide emitted more and costs higher than other
greenhouse gases during per ton production of Portland cements.
