Cement Soundness Tester — H-3350
Mold used to determine soundness of cement by measuring the expansion of cement when heated in an atmosphere of steam or boiling water. It consists of a brass split ring and two long parallel indicating arms. As cement expands, the ring is spread and an increased distance between the free ends of the indicating arms gives an index of soundness.
