Abstract:Vacuum processed reinforced concrete beams have proved superior to steel and timber for structural bracing elements (buntons) in mine shafts in the gold fields of the Orange Free State, South Africa. Concrete buntons fulfill strength and impact resistance requirements with the additional advantage that they can be streamlined to offer less resistance to flow of air for ventilation and better resist corrosion. Impact, bending and deflection tests are described. These tests of prototype buntons indicated certain weaknesses which were taken into account in redesigning the buntons.
