WENDLER, A. P.; MARQUES FILHO, J.; FRANCO FILHO, J. M. M.  e  BIANCHINI, M.. Grout enrichment of RCC for face of dams. Rev. IBRACON Estrut. Mater. [online]. 2014, vol.7, n.4, pp.709-722. ISSN 1983-4195.  http://dx.doi.org/10.1590/S1983-41952014000400009.

The construction of RCC dams emphasizes the minimization of interferences, such as execution of the upstream face, to ensure productivity. The study sought to evaluate the physical properties of the grout enriched RCC, replacing the conventional concrete usually employed in the face, using the same materials, concrete core, labor and equipment used in construction of the Maua Hydro Power Plant. Thus were made site experimental prisms (with different water / cement ratios and grout amounts) and subsequent core drilling, which were subjected to mechanical tests and permeability. The results showed that for grout water / cement ratio 0.74, the resulting material met the design specifications for cement consumption markedly lower (between 70 and 85% of the conventional concrete).

Palavras-chave : dams; rolled compacted concrete (RCC); grout enrichment; permeability.
