Abstract:
Until now the materials industry has been lacking an acceptable and practical test that demonstrates the relative brittleness and impact resistance of various concrete mixes and similar construction materials. A simple, portable, and practical test has been developed that performs this function. The number of impact blows delivered by a drop hammer are accumulated until the first visible crack occurs and until the test specimen is forced to separate by continued impacting. The test is especially suited to some of the newer and tougher construction materials such as fibrous concrete. Initial data shows that it can also serve as an indicator of other material properties such as toughness, strain capacity, and fatigue performance.
