In this paper it was studied and described possibility of siliceous and calcium fly ash for production of previously prestressed reinforced concrete elements, with the objective to decrease production costs and to improve physically - mechanical and durability properties of concrete as a civil engineering material. Fly ash as a mineral additive has a great role in a cement replacement and in improvement of permeability properties. Influence of fly ash to cementitious composite material is exceptionally good and desirable, especially for cements with application in aggressive media. For this purpose laboratory investigations of properties of concrete, with certain contents of fly ash was conducted, which was compared with properties of concrete with CEM I 52, 5 N cement type, to obtain optimal composition for prestressed reinforced concrete elements. |
