Cement, Energy and Environment

possible to produce concrete with high strength, water and frost resistance and durability at a high economic efficiency of produc on and applica on [4] having higher characteris c condi ons than the tradi onal cement. Hence, the concrete produced using Nano cement is normally of lesser pores, lower porosity, and consequently be er quality and Nano cement based-concrete has also higher hydrodynamic resistance to dal waves. Moreover, Nano cement is a good alterna ve to grout used for rehabilita on and strengthening of exis ng structures due to its high compa bility with different surfaces as Nano cement matrix has the ability to produce a higher percentage of calcium silicate hydrate and fill the pores well. The compressive and flexural strength of concrete with Nano cement a er 28 days increase by 60 % and 17% consecu vely [5].
