            This research was resulted of the characterization of cement paste composites (CPC) blended with palmyra fiber ash and surface-treated on short SWNT prepared by an electroless plating process. The cement paste composites included cement, 270 meshes of palmyra fiber ash and short SWNT. The design of experiment was divided into 3 conditions namely uncuring, 28 and 56 days in distilled water. The properties of CPC were carried out in chemical composition, physical, mechanical, mineral phase, microstructure and statistical analysis. It was found that in the chemical compositions an amount of silicon dioxide, aluminium oxide and ferric oxide were 51.53%, which was rated in class C. The bulk densities of CPC series between PFA10 (C) and PFA5AgSWNT0.01 (G) cured 56-day distilled water were an increased 38%. Then, the highest specific electrical resistivity of CPC series PFA5OSWNT0.03 (F) cured 56-day distilled water was 1.14±0.31 The highest compressive strength of CPC series PFA5AgSWNT0.01 (G) cured at 28-day distilled water was 25.45±2.00 MPa compared with the OPC (A) was an increased 5%. Which, the bulk densities of CPC series between PFA10 (C) and PFA5AgSWNT0.01 (G) were statistical analyzed the mostly cured at significant difference, α = 0.05. In addition, CPC series PFA5AgSWNT0.01 (G) mainly contained calcite, portlandite, quartz dolomite and ettringite were caused increasing compressive strength. And the SEM microphotograph were also displayed the calcium silicate hydrate, portlandite and ettringite. Consequently, the PFA was used to ability pozzolanic material using for lightweight concrete of CPC.
