(Universidade Federal de Santa Maria, 2015-12-16)
The use of mineral additions and substitutions in concrete production is highly beneficial to society. When used as substitutes for cement, they provide an alternative destination to polluting waste while contributing to ...
CARBONATAÇÃO ACELERADA EM CONCRETOS COM ADIÇÃO DE CINZAS DE LODO DE ESTAÇÃO DE TRATAMENTO DE ÁGUA
(Universidade Federal de Santa Maria, 2016-07-14)
Carbonation is a natural phenomenon for concrete structures and occurs due to the reaction between CO2, which is concentrated in the environment, and Ca(OH)2, which is present in the cementitious matrix. Carbonation reaction ...
RESISTIVIDADE ELÉTRICA DE CONCRETOS CONTENDO DIFERENTES TEORES DE CINZA DE CASCA DE ARROZ
(Universidade Federal de Santa Maria, 2005-10-21)
The durability of reinforced concrete structures derives from the protective effect provided by the concrete cover over the steel rebars. When the passivation of the steel is compromised, the whole structure is liable to ...
