ABSTRACT
The assessment of concrete's compressive strength is a pivotal component in ensuring the safety
and durability of structural elements in the construction industry. Two commonly employed
methods for this assessment involve the use of concrete cylinder and cube specimens. This research
endeavor undertakes a thorough investigation to compare the effectiveness and reliability of these
two specimen types in gauging concrete's compressive strength. A battery of compression tests is
conducted on these specimens, encompassing a wide range of concrete grades and curing
durations. The results are meticulously analyzed to evaluate the accuracy, repeatability, and
practicality of each testing method.
Preliminary findings indicate variations in the compressive strength values obtained from the
two specimen types. Factors such as specimen geometry, surface characteristics, and stress
distribution are scrutinized to elucidate the observed differences. Furthermore, the study delves
into the economic and logistical aspects of specimen preparation, testing, and storage. The insights
derived from this study have the potential to impact testing standards, quality control procedures,
and structural design protocols. Engineers, researchers, and stakeholders in the construction
industry will benefit from a nuanced comprehension of the advantages and limitations of each
specimen type. From the analysis carried out, the average compressive strength of concrete cubes
after a total curing period of 28 days was obtained to be 19.784KN/m2 while that of the cylinders
is 19.641KN/m2 , the difference was obtained as 0.143KN/m2 . This showed a very infinitesimal
difference of less than 1% of the designed strength (20 KN/m2 ).
