Influence ot the curing temperatures on the evolution of the compression strength of concretes made with different typer of cements

Manuel Fernández Cánovas1991-06-01Materiales de Construccion

In this paper we present the results obtained in the studies carried out on evolution of the compressive strength of identical concretes made with different types of cements based on the spanish standard UNE 80 301 when they are subjected to critical temperatures (5 °C and 35 °C), compared with the same concretes cure…

Electrochromic Behavior of Nickel Oxide Electrodes: II . Identification of the Bleached State by Raman Spectroscopy and Nuclear Reactions

S. Cordoba-Torresi、Anne Hugot‐Le Goff、S. Joiret1991-06-01Journal of The Electrochemical Society

Three different types of nickel oxide electrochromic films are colored and bleached in 1 M KOH solution: porous NiO prepared by anodic oxidation of nickel, NiO ( OH ) x obtained by reactive evaporation, and Ni ( OH ) 2 cathodically deposited. Their crystallographic and chemical identification in the colored and bleach…
