The moulds are used for preparing the specimens for the purpose of determining the length changes (shrinkage/expansion) in hardened concrete and hydraulic cement mortar .
All moulds surfaces are protected with anti-corrosion oil. Also all parts of the moulds are matchmarked.
The moulds are supplied complied with the steel inserts screwed on.
According to all standardized test methods for determining the length changes under different conditions, the muolds are used together with the any Cooper Length Comparators (TC-1170) fits the specimens sizes.
TC-1170 Large Type Digital Length Comparator can be used cement/concrete prisms up to 100mm width Adjustable beam height (except dial gauge) is 365mm and 220mm horizontal clearance). TC-1170 Consists of a 12.7×0.001 mm graduated digital dial gauge which is mounted on a steel frame.
Reference rod and other equipment be should ordered separately.
