Aggregate Impact Value (AIV) Test Machine

Aggregate Impact Value (AIV) Test Machine is used to evaluate the resistance of coarse and medium-grained aggregates to sudden impact forces under standardized testing conditions. A rigid steel frame with a fixed base plate and a precision-machined vertical column ensures accurate axial transfer of impact energy directly to the aggregate sample cup, minimizing energy loss and test variability. The lift-and-release mechanism of the Aggregate Impact Value (AIV) Test Machine guarantees that the impact hammer is dropped from the same height for every blow, eliminating operator influence and ensuring repeatable results. The impact hammer travels smoothly along precision guide rails, maintaining correct alignment throughout the test sequence. The test set includes a steel sample cup manufactured to standard dimensions and a matching tamping rod for consistent specimen preparation. A digital counter records and displays the number of applied blows, allowing precise control of the test cycle. Robust construction and precise mechanical components make the Aggregate Impact Value (AIV) Test Machine suitable for routine quality control, research laboratories, and aggregate production facilities.
