The Properties of Nanocarbontubes Cement Mortar Incorporating Mineral Additives

The purpose of this paper is to discuss the influence of mineral additives i.e. metakaolin, silica fume, rice ash and fly ash incorporating with nanocarbontubes mortar composites. The effects on compressive strength at 28 days were also discussed and presented. Cement content of 500 kg/m3, water/cement ratio of 0.6 and aggregate/cement ratio of 2.75 were adopted for the mix propotion. 1%, 3% and 5% of nanocarbontubes in mortar were combined with 15% of mineral additives. The results show that mixtures of nanocarbontubes with 15% of metakaolin produce better strength compared to normal mortar. Meanwhile with addition of fly ash and rice husk ash the strength were decreased. The electrical resistance for all mixes at 28 days were also discussed and presented. The higher percentages of nanocarbon with addition of all mineral additives resulted in lower electrical resistance properties
