ABSTRACT:
A concrete mix comprises a cementing agent and aggregate, the aggregate comprising vesiculated beads of cross-linked resin which beads contain an average of at least 2 thin-walled foraminous cells to provide communication between the vesicles within said bead and the exterior of said beads to allow water to move into and out of said beads. This reduces the density of the concrete and the beads hold water to help control the cure.
