ABSTRACT
This research work entails the production of dual/twin cell concrete cube molds by fabrication
according to the British Standards with a 4mm thick metallic sheet material (Non-absorbent)
that is capable of receiving, withstanding and withholding both concrete and accessible water
coming along with it without leakage or warping. The opposite faces/walls of the mold are
smooth, rigid and 150cm apart, thus forming a 150x150x150cm cuboidal cell with the base of
each wall dipped into a slot of equal thickness with the thickness of the plate (4mm). At the base
of the mold is a vertical anchor with a threaded tip attached to the base by welding to hold the
longer walls together firmly through the U-protrusion to the shorter walls. The two opposite
longer walls were formed by joining two 4mm thick metal plates together to form 8mm thickness
walls by making a rectangular cut on one plate and then welded together from that place the cut.
Thus, each opposite angle formed between shorter cell separators and the 8mm thick longer
walls are edifices of a perfect 90-degree angle, making the two cells conform by all standards.
On completion, the double-cell apparatus was fed with concrete, and each cell was tamped as
per 25 strokes of the tamping rod. Then, it vibrated for two minutes to test the integrity and
possible leakages between joints. It was found to be of proven integrity, without leakages, easy to
couple and de-molded. It was therefore recommended that practical under-field or laboratory
conditions be used to determine the compressive strength of concrete cube tests; this will
provide an idea of all the characteristics of concrete.
