✦ Synopsis

The EU project COMPASS, Compatibility of Plasters and renders with Salt loaded Substrates in historic buildings, aimed at improving the maintenance of monuments by means of a better understanding of the working principles of the plasters and the damage mechanisms induced by salt crystallisation. Salt damage was effectively studied modelling the moisture and salt transport and degradation (irreversible dilation) and a fast and efficacious salt crystallisation test developed. Practical results were the assessment of the requirements for plasters to be used on salt loaded substrates and guidelines for selecting plasters suitable for different situations. The dissemination of the results was also entrusted to the expert system MDDS.

The choice of a repair plaster or render by architects often appears to be the result of fortuitous circumstances, such as prior experience with a plaster or a recommendation by a producer. Seldom is the choice based on a sound assessment of the state of the building and the wall that is to be repai

We have investigated whether a plaster which has two plaster layers with different pore sizes can act as a salt accumulating plaster system, in which salt crystallizes in the base layer of the plaster and not in the substrate or at the external surface. We used two substrates; fired-clay brick and B

It has long been known that highly soluble salts or hydrate-forming salts can damage porous building material. There is a real challenge to provide salt assessment in compliance with good monuments diagnosis and restoration practices. The salts present in the masonry can be analysed qualitatively an

N-Substituted 5-piperazin-1-yl-1,3,4-thiadiazol-2-amines that fail to undergo Groebke-Blackburn type MCR with aldehydes and isocyanides provide fair to good yields of the respective 2-piperazin-1-ylimidazo[2,1-b][1,3,4]thiadiazoles when such reaction is promoted by an equimolar quantity of trimethyl
