Lightweight concrete exhibits many advantages over traditional concrete such as lower density and thermal conductivity and an easier, cheaper, less energy-consuming manufacturing process. In order to extend its applications, there is a need to study its behavior in fire situations. Due to that, the aim of this study was to assess the fire resistance of foam concrete, depending on its thickness and the foaming process applied. Fire resistance was assessed according to EN 1363-1. The results indicate the usefulness of foam concrete in terms of isolating fire temperatures for discontinuous partition filling that are consequently a real alternative to dedicated solutions in the field of passive fire protection. The density of foam concrete was shown to have a large effect on the ability to insulate fire temperatures with a standard material preparation process. It was also noted that changing the method to continuous foam feeding may result in the achievement of similar values while maintaining foam concrete low density.

“…The effect of increasing cure time and age on UPV will eventually be seen as an improvement in UPV [24]. With paste hydration, this can be explained by a decrease in empty spaces or an increase in the gel-space ratio [25].…”

This study intended to observe the effectiveness of foamed concrete jacketing using fibreglass fabric with the goal to enhance its durability properties. LFC of two densities of 500 kg/m3 and 1000 kg/m3 were cast and tested. The LFC specimens were wrapped with 1 layer, 2 layers and 3 layers of fibreglass fabric. The parameters evaluated were porosity, water absorption, drying shrinkage and ultrasonic pulse velocity. The results revealed that adding fibreglass fabric to LFC decreased its porosity and water absorption for both densities. Fibreglass fabric did more than only prevent cracks; it also reduced the drying shrinkage and increased the ultrasonic pulse velocity of LFC. Three layers of fibreglass fabric offered optimal results for all properties studied. As a result of the fibreglass fabric's ability to prevent moisture evaporation and consequent dimension changes in the confined LFC, drying shrinkage strain was kept least. The use of fibreglass fabric not only prevented water from escaping but also stopped it from penetrating the cement matrix. This preliminary study shows a huge potential to utilise fibreglass fabric as a strengthening medium to improve the durability performance of LFC.
