Repair mortar is commonly used to rehabilitate reinforced concrete structures or components that exhibit a relatively high level of distresses. Yet, the repair mortar can be contaminated by salt from its service environment. This work employs a two-dimensional finite element model to investigate the non-stationary transport behavior of ionic species in salt-contaminated and water-saturated repa...

The design of repair mortars started from the characterization of the original mortar samples preserved in small areas in the floors of the Dungeon Tower, Bač Fortress. Two materials (waste brick and clay material) were investigated in order to select the pozzolanic material which later was a component of the repair mortar. Based on the compatibility test of the examined old mortars and of the ...

the objective of the present work is to analyse the potential of using non-classical additions in concrete and mortar compositions such as coal bottom ash (ba) and biomass ash (bio), as partial replacing binder of ordinary portland cement. it is intended to deal with production of these type of wastes and its accumulation and contribute to the minimisation of carbon and embodied energy in const...

Different structural parts of monuments and historic buildings were based on stone as the main building material, such as masonry and foundation, while many types of stones were also used for decorative, architectural elements, such as reliefs, cornices, corbels, colonnettes. The preservation of stone elements is crucial for the continuity of these structures. Mortar on the other hand is an art...

Protecting the built cultural heritage is one of most important tasks in architectural practice. The process repair time-consuming, weather-dependent, and sensitive to materials applied. Introducing new historic building order decrease time needed for repair, brings some risk preservation process. common material masonry lime mortar. Adding cement mortar can improve mechanical properties speed ...

A laboratory procedure aimed at generating a progressive deterioration of the interface between brick and mortar layers in controlled experimental conditions was developed at the Non Destructive Testing Laboratory of the Politecnico di Torino. It is intended as a preliminary stage in the design of a pre-qualification procedure to be applied to repair mortars for restoration of historical masonr...

One of the main problems with hydraulic structures is that floating silt, gravel, ice sand, boulders, and other materials circulating over a concrete surface have an abrasive effect causes to abrade. Abrasion degrade, which could eventually expose reinforcing corrosion. In addition section loss, reinforced structures’ endurance may also be problem. Repair mortars are used restore surfaces been ...
