Abstract Chloride ions diffuse through the concrete cover and interact with the cement hydration products. As a result, some chloride ions become chemically and/or physically bound. Free chloride ions are the primary cause of steel corrosion in reinf

Lime mortar is one of the oldest building materials. In Mexico, ingredients added to it to enhance its properties may include cactus mucilage, among others. We have evaluated the effect of adding, at two different concentrations, mucilage from Opunti

During steam curing of concrete, temperature and moisture gradients are developed, which are difficult to measure experimentally and can adversely affect the durability of concrete. In this research, a model of cement hydration coupled to moisture an

Unilateral magnetic resonance was used to obtain the CPMG T 2 decay at different positions along 6 cm long cement paste samples. The aim was to detect the carbonation front based on changes in the pore structure caused by accelerated carbonation and
