The Plunger Penetration Apparatus is designed to determine the consistency of fresh mortar, lime, and masonry cement by measuring the depth of penetration of a standardized plunger into the material.
This method provides a reliable assessment of workability, ensuring that the material meets the required consistency for application in construction projects.
The apparatus consists of a sturdy steel base with a recess to accommodate the test cup and a vertical column supporting the plunger assembly, ensuring precise alignment during testing.
The plunger assembly, weighing 90 g, is designed to drop from a height of 100 mm, providing consistent and repeatable penetration measurements.
A tamper with specified dimensions is included to prepare the mortar sample uniformly within the test cup, enhancing the accuracy of the test results.
