In order to prevent condensation within the cellular lightweight concrete (CLC) a polymer-clay nanocomposite (PCN) was developed. The PCN showed a high moisture absorption capacity above 90 % RH, thus capturing excess humidity. The material can be produced cost effectively with relatively simple methods. It is also easy to apply in foam concrete.
Additional beneficial properties are: When applied to a carbon fiber grid reinforcement it increases the adhesion of the grid within a reactive powder concrete, thus increasing the capacity of the carbon grid reinforcement towards tensile or flexural stress.
