| description | This study investigates the physical qualities and strength properties of
representative cements manufactured by different brands in Bangladesh. The
physical and strength properties such as normal consistency, initial and final
setting time, density, specific gravity, fineness, and compressive strength of
cement mortars as well as concrete cylinders were investigated experimentally.
Using CEM II/B-M type cement, a total of 300 test specimens are prepared to
determine those parameters. In this case study, specimens were prepared from
ten different representative cement industries of Bangladesh and tested as per
ASTM specifications. The experimental result shows that the physical and
strength parameters of nearly all the representative cement samples are within
the ASTM recommended ranges that ultimately proofs the quality of
Bangladeshi Cement. The relationship between mortar and concrete strengths
from the same batch of cement has also been investigated. Besides, a regression
analysis has been conducted to find relationships between the concrete strength
and their age of curing. The influence of initial and final setting times on
concrete strength is also investigated. This study also provides the relationships
between compressive strengths, between mortar and concrete cylinders at
different ages. These age dependencies of concrete strength will help to predict
the actual concrete strength at the early age of curing which may ensure faster
construction work. |
