Conclusion

Thetestwassuccessfullydoneusingtheavailablematerialsandtheequipment.Thecubethat wasbeingusedforinvestigationof thecompressive strengthwas2 inchby 2 inch.Themortarcubeswereof 7.79 squareinch,andtheloadof 50743 lb wasappliedontothecubeto determineitcompressive strength.Theresultfrom thecrushing machineindicatesthatthemortarcubehas thecompressive strengthof 6513.86 psi.

Whencomparedto theearlierresultspublished,itcan be fitfortheusein construction.Themortarbriquette wasusedto determinethetensile strengthof themortar.ItwaslabeledW-1 whilein thelaboratory.

Tensilestrengthof mortarbriquette wasmeasuredusingthemortarbriquette machineprovidedin theconcretelaboratory.

Thelab experiment(practicaltests)aimedat investigatingthecompressive strengthandtensile strengthof themortarcubesandmortarbriquettes.In thisexperiment,theresultshowedthatconcreteis fragilein tensionandstrongin compressionas indicatedby theresultsdiscussedabove.

Basingon theresultsobtainedabove concreteneedsto beproperlycompacted,placed, andcuredat thesuitableconditionssothatitcan gainenoughstrengthwithin thespecifiedperiod.Becauseconcretehas littletensionforceresistanceandhas highcompressive forcestrength,itis, therefore,essentialto reinforceitwith thesteelbarssothatitcan resistbothtensionandcompressionforces.

Thebrickbeingone of theprimaryconstructionmaterials,itwasinvestigatedto determinetheir compressive strengthandthestrengthwasfoundto reasonablyacceptableas comparedto thoseusedearlierin developmentfrom theknownstandard.Thebrickhadtheareaof 50.38 squarecentimeters excludingtheareaof holes.
