Estudo da variação na resistência a compressão de concretos convencionais devido aos diferentes tipos de cura
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Construção Civil, 2013-07-15)
Why the curing of concrete is often neglected? Our desire for rapid production is usually the 1st culprit. People often have no patience, especially when time is money, and healing requires patience and attention to detail. ...
Comparativo entre retíficas de corpos-de-prova de concreto
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Construção Civil, 2012-05-15)
The concretes are evaluated in terms of its resistance to compression. However, this assay may provide dispersion results. Among the factors that can cause these quoted dispersions are: flatness, parallelism and perpendicularity ...
Avaliação de cloretos pelo método de aspersão de solução de nitrato de prata
(Universidade Católica de Pernambuco, 2011-06-13)
