Análise do cimento álcali ativado quando sujeito à reação álcali-agregado
(Universidade Tecnológica Federal do ParanáPato BrancoBrasilDepartamento Acadêmico de Construção CivilEngenharia CivilUTFPR, 2016-11-22)
The growing environmental concern has stimulated studies for the development of alternative cements, with reduced greenhouse gas emissions in its manufacture. One of these is the alkali activated cement (CAT), which in ...
Cracking due to alkali-silica reaction in slab at the Jaguari hydroelectric power plant - A qualitative studyesEstudio cualitativo sobre fisuración debida a la reacción álcali - sílice en el forjado de la represa hidráulica de Jaguari
(2013-01-01)
The concrete structures of Jaguari Hydro Power Plant (HPP) display cracks due to the occurrence of Alkali-Silica Reaction (ASR). The qualitative analysis of the cracks that occur in the slab of the water intake structure ...

Alkali-silica reactivity of basaltic aggregates of Mesopotamia Argentina: Case studies
(Springer Heidelberg, 2019-10)
This work consists of two stages; first, studies were conducted to evaluate the potential reactivity of crushed material (6–20 mm fraction) from two quarries (named A and B) producing basaltic aggregates in the northeast ...
Reação álcali-agregado: influência da granulometria do agregado
(Universidade Católica de Pernambuco, 2015-11-25)
Modeling studies the RAA expansion are generally limited by the difficulty due to the heterogeneity and reactive aggregate size range. This work aims to study the issue and help in developing models to predict the potential ...
