Influence of the moisture content on the dynamic modulus of elasticity of concrete made with recycled aggregate
(ANTAC - Associação Nacional de Tecnologia do Ambiente Construído, 2019)
Electrical resistivity measurement of unsaturated concrete samples
(ICE Publishing, 2014-04)
Electrical conduction in concrete primarily occurs via the liquid in pores. Since concrete resistivity is sensitive to moisture content, resistivity can be used to infer other moisture-dependent concrete properties. However, ...
Finite element analysis of concrete cracking at early age
(TECHNO-PRESS, 2011)
The study of the early age concrete properties is becoming more important, as the thermal effects and the shrinkage, even in the first hours, could generate cracks, increasing the permeability of the structure and being ...
Avaliação do módulo de elasticidade dinâmico de concreto produzido com agregado graúdo reciclado de concreto
(Universidade do Vale do Rio dos Sinos, 2012-01-13)
The construction industry is one of the largest solid waste generator. For this reason, it is important to adopt a new model aiming for thereuse of construction waste and thereby achieve a more sustainable development. In ...

Estudo de aditivos impermeabilizantes no comportamento do concreto
(Universidade Tecnológica Federal do ParanáCampo MouraoBrasilDepartamento Acadêmico de Construção CivilEngenharia CivilUTFPR, 2018-12-17)
Concrete is a porous material and thus allows the absorption of water in its structure. This feature can adversely affect the life of the structures and, in order to extend the life of a building, waterproofing systems ...
High-strength self-curing low-shrinkage concrete for pavement applications
(TAYLOR & FRANCIS LTD, 2010)
High-performance concretes (HPC) that are designed to possess high early strength, self-curing capabilities and low shrinkage may potentially improve rigid pavement performance. A multi-scale experimental programme examined ...
Estudo da trabalhabilidade de concreto para blocos de vedação com consistômetro de vebe
(Universidade Tecnológica Federal do ParanáCampo MouraoBrasilEngenharia CivilUTFPR, 2015-06-18)
The workability of concrete is an essential term to achieve the performance objectives in construction. Through it, and to suit the different types of concrete needs. For drier concrete used in the production of sealing ...
Análise de concretos de pós reativos a base de carbonato extra leve, mica e carbonato de cálcio
(Universidade Tecnológica Federal do ParanáCuritibaDepartamento Acadêmico de Construção Civil, 2012-05-31)
The constant search and need for stronger concrete resulted in new techniques and studies where improved mechanical properties through the elimination of coarse aggregates and the betterment of granulometric composition ...
Experimental shrinkage testing on concrete masonry units and walls with different curing conditions
(2016-12-01)
This paper reports on an experimental program for measuring shrinkage of concrete masonry units and walls. Tests were carried out on blocks of 4.5, 8.0 and 14.0N/mm2 strengths (with respect to gross area); different suppliers ...
