This paper presents an experimental study on the behaviour of rendering mortars used to rehabilitate buildings subjected to rising damp and consequently affected by efflorescence. This study was initiated by the chara...
High temperatures of the asphalt concrete pavements in summer contribute to the heat island phenomenon in the urban areas. The effective cool-pavement technologies are sought to mitigate the pavement environment. In t...
This study aims to evaluate the presence of free chlorides by the silver nitrate colorimetric spraying method in mortars made with Portland cement CP II Z-32. In order to make an assessment beyond the qualitative anal...
SIM (semi interlocking masonry) is a kind of innovative building system for mortar-less walls. It utilizes a special method of interlocking SIM bricks that allows relative sliding of brick courses in-plane of a wall...
Crushed fine aggregates are widely used for full or partial replacement of natural sands in concretes. The crushed sands present different characteristics from the natural sand, especially if taking into account the c...
Extra-cellular compounds, secreted by microorganisms into their surroundings, can be integrated in concrete composition as admixtures. These substances are important in biofilm formation and some of them can be used a...
Often masonry walls of historical buildings are subject to rising damp effects due to capillary or rain infiltrations. In the time, their cyclic action produces decay and delamination of historical plasters. An experi...
Nowadays, technologies in construction field have offered several kinds of chemical admixtures, which offer different behaviors at the fresh state of the batch and by consequence, it is resulted with different mechani...
This study proposes a model to determine the content of cement in mortars using the background of X-ray diffraction (XRD) spectra taking advantage of the fact that fluorescence radiation for the Cu anticathode is di...
The work presents an experimental study held with shells of molluscs of the species Anomalocardia brasiliana and Tivela mactroides, commonly found in the Northeast coast of Brazil. A local community living from the co...
