The effects of carbonaceous particles and heavy metals in the interaction between sulfur dioxide and mortars were investigated in a laboratory exposure system. Simulation experiments were carried out in a flow chamber where temperature, relative humidity and SO 2 concentration were controlled....
Corrosion of reinforcement bars due to chloride ingress is a well known problem in reinforced concrete. Several methods have been adopted to protect reinforced concretc, and one of them is to provide added protection to the concrete surface in the form of surface treatments such as silanes and...
The present paper tries to contribute to quantifying the relationship between the amount of corrosion and cover cracking. The variables studied were: cover/diameter (c/ø), proportions of cement, w/c, cast position of the bar, transverse reinforcement and corrosion rate. The corrosion is...
Fatigue tests were carried out on notched microconcrete beams subjected to three-point bending tests in a saturated atmosphere. The feature of the crack growth was studied by means of the replica technique associated with scanning electron microscopy, in conjunction with the measurement of the...
The principles for control of cracking in concrete structures due to imposed strain are investigated in this paper. The effects of uniform and non-uniform cooling and shrinkage are studied in medium-thick walls with regard to the amount of reinforcement necessary to distribute cracks. The...
A survey was performed to find in the literature theoretical models suitable to the description of the triaxial creep behaviour of plain concrete at high stresses. The considered models are based on the theory of elasto-viscoplasticity with damage and are mainly addressed to the domain of...
Based on equilibrium and compatibility conditions, as well as a softening stress-strain relationship for concrete, a truss model theory was presented to predict the behavior of low-rise structural walls under static loads. In this paper, shake table tests on low-rise structural walls are...
In this paper, numerical analysis of structural masonry subject to a uniform in-plane tensile stress/strain field is investigated employing various homogenisation techniques. Here, structural masonry is regarded as a composite material with brick, bed joints and head joints as its constituents....
