Comparative Analysis Of The Chemical Composition, Normal Consistency And Setting Times Of Some Selected Brands Of Ordinary Portland Cement:- Ndianefo Chinonso V
ABSTRACT
This study attempted to examine
the experimental study ofthe effect of brands of ordinary portland cement (OPC)
on the consistency and setting times of cement paste. Cement is the most
ubiquitous cement and is produced in high-temperature kilns. The ban on the
importation of cement in Nigeria has given room for investors to establish more
cement factory industry Tire investigation will be done with different cement
products, using laboratory analysis. The major factors affecting the setting
time of cement are cement composition, water-cement material ratio (w/c),
environmental conditions like temperature & humidity, and admixtures like
Accelerator and Retarder. This study has suggested Some ofthe brands of cement
available in Nigeria conform with BS 12: part 2, 1992 in terms of silica
content, but with a slight variation in A12O3. All the brands under
investigation have CaO within the specified limit by the BS standard code The
brands can be recommended for large concrete pours with provision for expansion
joints to prevent cracking.. All the brands under investigation have CaO within
the specified limit by the B S standard code.
