Stability and Dependability of Built Building Structures and Factors Contribute to Efflorescence

Abstract

Modern pigmented concrete products in the early 1950s, coloured concrete products have opened up new possibilities in the field of building and landscape design. Ironically, these coloured concrete products have also opened the door to a new visible phenomenon that is known as efflorescence. The unfortunate reality is that hue shifts in the completed goods are always the adversary, regardless of how carefully the raw materials are chosen or how conscientiously the manufacturing standards are adhered to. Calcium carbonate efflorescence is the likely cause of the colour inconsistencies that are sometimes referred to as fading in many instances. One might wonder how efflorescence might still occur even though the manufacturer has supposedly done everything properly, such as using excellent materials, having a good mix design, exceeding the strength requirements, and meeting the manufacturing schedule. This mind-boggling issue may be answered if one were to do in-depth research into the process underlying efflorescence. Even though a great deal of effort has been put into researching the phenomenon of efflorescence, and even though researchers from all over the world have come to a large extent of an agreement on the mechanism behind the formation of efflorescence, there are still no effective methods that concrete manufacturers can use to prevent the formation of efflorescence on finished concrete products.
