TEN PERCENT FINE VALUE

The Ten Percent Fine Value (TFV) test measures the crushing resistance of fine aggregates under controlled conditions. The procedure requires loading the sample within a defined time up to a preset load or displacement threshold, while precisely monitoring displacement throughout the test.

A Matest compression machine is required to perform this test, providing accurate control of load and displacement, ensuring repeatable and reliable results. This test is essential for assessing aggregate quality, supporting material selection, and guaranteeing compliance with BS 812-111 standard in construction and engineering projects.
