Abstract
A concrete test cylinder mold formed of expandable polystyrene and which is used to form geometrically uniform concrete test cylinders that accurately reflect the structural properties of the concrete mix used to form the test cylinders despite fluctuations in temperature to which the test cylinder may be exposed during formation within the mold. The mold is constructed and configured such that compression testing of the concrete test cylinder may be conducted while the cylinder is still in the mold. A specially designed heat shield may be used in unison with the concrete test mold to form, at least in part, a system by which heat further may be retained within the system during formation of the concrete test cylinder.
Claims5
A system for forming a concrete test cylinder comprising:
- a concrete test cylinder assembly comprising:
- a mold formed, at least in part, of expanded polystyrene, and further comprising a generally cylindrical shaped body having an exterior wall oppositely situated to an interior wall, and an open-ended top side oppositely situated to a bottom side, wherein the top side and the bottom side of the mold are positioned transverse to the exterior and, interior walls of the mold, and further wherein a chamber is coterminously formed with the top and bottom sides of the mold and is immediately surrounded by the interior wall of the mold;
- and
- a sleeve formed, at least in part, of expanded polystyrene, and further comprising a generally cylindrical shaped body defined by an exterior wall oppositely situated to an interior wall, and by an open-ended top side and an oppositely situated open-ended bottom side, wherein the top and bottom sides of the sleeve are transverse to the exterior and interior walls of the sleeve, and, further wherein a uniformly formed cylindrical-shaped chamber is surrounded by the interior wall and is coterminous with the top and bottom sides of the sleeve;
- wherein the mold is disposed in the chamber of the sleeve such that the exterior wall of the mold physically abuts the interior wall of the sleeve, and such that the bottom side of the mold is coterminous with the bottom side of the sleeve, and the top side of the mold is coterminous with the top side of the sleeve, wherein the chamber of the mold holds a concrete mix, and wherein the sleeve insulates the concrete mix during cure of the concrete mix;
- and
- a heat shield, wherein the heat shield comprises an expandable polystyrene material, and wherein the assembly is disposed within the heat shield.
