1.Introduction:
Concreteisawidelyusedconstructionmaterialduetoitsstrengthanddurability.However,variationsinmixtureproportionsandcuringconditionscanaffectthestrengthofconcrete.Hence,standardspecimensarepreparedandtestedtodeterminethecompressivestrength,whichisvitalfordesigningstructuresappropriately.Thispaperdiscussestheanalysisofstrengthtestingmethodsandprovidesrecommendationsforimprovingtheaccuracyandreliabilityoftestresults.
