What is a Mechanical Cement cylinder?
A Mechanical Cement cylinder is a thin-walled cylinder. It can be designed and made from any suitable material of adequate size and tensile strength to resist the lateral pressure generated when the crushed stone is placed under load. This lateral pressure can be calculated using established engineering formulae. It is the tensile strength of the Mechanical Cement cylinder that generally defines the overall strength of Mechanical Concrete and not the crushed stone. A Mechanical Cement thin-walled, cylinder can be made of single material or of composite materials. For example, the cylinder can be made of steel or plastic, or it can be made from a recycled auto or truck tire with both sidewalls removed. The tire-tread cylinder is no longer a tire but through remanufacturing becomes a tire derived cylinder, TDC.
