TL;DR: In this paper, the effect of mortar composition and strength on the flexural bond strength of masonry has been examined by testing stack-bonded prisms using a modified bond wrench test set-up.
Abstract: This paper deals with an experimental study on flexural bond strength of masonry using various blocks in combination with different mortars. Flexural bond strength of masonry has been determined by testing stack-bonded prisms using a modified bond wrench test set-up. The effect of mortar composition and strength on the masonry's. flexural bond strength using three types of masonry units (stabilized mud blocks, stabilized soil-sand blocks and burnt brick) has been examined. The effect of the masonry unit's moisture content on flexural bond strength has also been studied. Increases in mortar strength lead to increased flexural bond strength for cement mortar, irrespective of the type of masonry unit. It has been found that combination mortars, such as soil-cement mortar and cement-lime mortar, lead to better bond strength compared to cement mortars. The moisture content of the masonry unit at the time of casting has displayed significant influence on the flexural bond strength of the masonry. It has been found that for each type of masonry unit, an optimum moisture content exists, beyond which the flexural bond strength falls off quickly.

TL;DR: In this paper, the authors apply both the mechanical field and the thermal field in order to model frictional contact, the energy transfer between the surfaces as well as the frictional heating, and a series of simplifications are considered so that a wide range of established numerical techniques for Mortar methods such as segmentation can be transferred to IGA.

TL;DR: In this article, a study was performed on the corrosion-inhibition mechanism of three phosphate compounds (sodium monofluorophosphate, disodium hydrogen phosphate and trisodium phosphate) for steel rebars embedded in ordinary Portland cement (OPC) mortar exposed to 3% NaCl solutions.
Abstract: A study was performed on the corrosion-inhibition mechanism of three phosphate compounds (sodium monofluorophosphate, disodium hydrogen phosphate and trisodium phosphate) for steel rebars embedded in ordinary Portland cement (OPC) mortar exposed to 3% NaCl solutions. The corrosion inhibitors were deployed in two different ways: by migration after the curing period, through the immersion of mortar specimens in aqueous solutions containing the soluble phosphates; and by initial admixture of the phosphate powders in the OPC mortar. The tested specimens were studied using electrochemical corrosion potential and linear polarisation resistance for 70 days of experimentation. A correlation was found between the phosphate content of the specimens (by migration or admixture) and the steel corrosion rate. The results indicate that all the phosphates have the ability to inhibit steel corrosion in mortar.
