CA 2669703
There is provided a concrete mixture containing EPS beads that are coated with a functional composition. The coating composition removes a restrictive gas layer on EPS beads by adhering to the beads and having a suitable porosity to allow the gas to dissipate, and, thus, can enable a strong attraction and permanent adherence of a material, having cementitious properties, such as, for example concrete, to the EPS beads. The adherence of the material to EPS beads creates a mixture that can be pre-cast into building blocks or panels significantly lighter and sturdier structurally than existing methods allow for. The beads can be specifically made to correct size and density for the process in pre- expanders, comprising fluid bed dryers, and then treated through the spray application of the coating composition.
