New advances in the carbonation of aluminous cement. Alkaline hydrolisis
Materiales de Construccion, 1999 The carbonation process of aluminous cement in presence of high alkali content is studied. In this work, the formation of a compound which formula is close to K4Al6(CO3)11-x(OH)2x(H2O)y is shown for the studies samples. The aluminous cement carbonation

Structural Control and Health Monitoring, Volume 2025, Issue 1, 2025.Concrete resistivity (ρ) is commonly monitored in situ using sensors based on the rebar‐disc (RDM) or four‐electrode (FEM) methods. This study validates, for the first time in reinforced concrete, an innovative corrosion sensor approach (CSA) previously tested only in simulated pore solutions.

The process for designing and constructing the Sunpu Kaikan
JAPAN ARCHITECTURAL REVIEW, Volume 7, Issue 1, January–December 2024.Tange and a model of Sunpu Kaikan. Abstract This study aims to reveal the difficulty of realizing large hyperbolic paraboloid (HP) shell structures comprising reinforced concrete in earthquake‐prone Japan in the 1950s. The analysis focused on the design and construction of Sunpu Kaikan, focusing on the roles of Kenzo Tange and Yoshikatsu Tsuboi ...

Influence of relative humidity and temperature on-site corrosion rates
Materiales de Construccion, 1998 When the steel rebar depassivates, the corrosion starts to develop at a rate which mainly depends upon the moisture content in the concrete pores. In natural outdoor exposure conditions, the moisture content will depend not only on the relative humidity ...
