Salts in Porous Construction and Building Materials

PCA’s Dr Paula Lopez-Arce will be releasing a set of short papers focussing on ‘salts in porous construction and building materials’, aiming to provide a better understanding of the problems which affect the durability of many types of buildings, materials and structures in all kind of climates and weather conditions.

What you will learn from the technical papers

This series of papers on salts in porous construction & building materials brings together a huge amount of published research on this topic that can be turned into practical, successful applications while answering generic questions such as:

  • Type and sources of salts / Decay of building materials: Why are salts important? Where are they coming from? How do they interact and behave with the environment and the building materials?
  • Concentration, distribution and measurement techniques: Where are the salts localised? How can we identify and measure them?
  • Remediation solutions: Which remediation actions can be taken? Are these effective?

Get involved

There is a distinct lack of well documented, applicable and published case studies dealing with problems of salts in non-historic buildings and the experiences of PCA members dealing with salt problems in residential buildings will be invaluable.
