Drop shape analysis - innovative implement in renovation area

SUMMARY: The destructive impact of water and solutes (mostly salt solutions) to prevent in building sector are often used injection materials for refurbishments. These materials are based on raw substances whose dilution will be applied. Refurbishments can be carried out with an additional horizontal moisture barrier, hydrophobic treatments and coatings. The resistance against water load is evaluated by material properties like moisture content, water absorption, diffusion resistance, deliquescence and so forth. Additional to the common evaluation methods in this work drop shape analysis is used to assess water resistance of building material. The obtained values are contact angle, decrease of contact angle by time, surface tension and wettability. The aim of this work is to evaluate the significance, practicability, possibilities and meaning of drop shape analysis in building sector.
