There is provided a concrete mixture containing EPS beads that are coated wi th 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 g as 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. Th e 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 i n pre- expanders, comprising fluid bed dryers, and then treated through the spray application of the coating composition.
