Recently there are many study on the effect of improving the compressive strength of MWCNT-cement composites. However study related to MWCNT-cement yet insignificant to the domestic. The MWCNT have excellent mechanical characteristics which are mixing cement. MWCNT-cement composites can be expected improving compressive strength. This parametric experimental study have verified to increasing compressive strength of mortar composites mixing MWCNT as W/C, curing age.
