mineral additives in cement manufacturing

  • Concept of Evaluation of Mineral Additives' Effect on ...

    For optimal w/c ratio for the investigated cement paste with and without mineral additive, we consider 0.4 (w/c ref). In addition, reference cement pastes without the subjected mineral additive with higher (w/c–up, e.g., 0.5) and lower (w/c–down, e.g., 0.3) water to cement ratio should be prepared.

    Cement content of 500 kg/m 3, 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.
