This is a study into the phase transitions of aerosol composed of the ternary system ammonium sulfate (AS) – malonic acid (MA) – water using infrared extinction spectroscopy. Twelve compositions were studied in both deliquescence and efflorescence mode experiments. The presence of a MA fraction, by dry mass, (fMA) of 0.1 in an AS aerosol altered the relative humidity at which the phase transiti...

The tinting strength of the pigments used to colour concrete products such as pavers and roof tiles is of particular significance. Pigments with high tinting strength will create a more intense colour than those with lower tinting strength, even if the same quantities are used. This means that smaller amounts of the pigments with high tinting strength are needed to create a certain colour inten...

Salt efflorescences from metal sulphides and their waste are important drivers of pollution both in around mining areas. However, little is known about these supergene minerals, particularly the areas Mediterranean. This study aims to characterise saline leachates a Mediterranean area located Southeast Spain. The physicochemical characteristics were determined using stereomicroscopy composition...

Understanding the dynamics of precipitation and crystallization as salt solutions evaporate from porous media is importance in context preservation historical monuments, understanding soil nutrient content, design evaporators for use distillation plants. Transient advection-diffusion equations govern mass fraction profile solution inside medium. These governing are solved to obtain solute withi...
