LARGE-SCALE CONCRETE TESTING

摘要

Large-scale laboratory testing using large specimens is not commonly done. Theequipment and manpower required to produce the required concrete volume and theapparatus required to restrain and apply loads can be quite substantial. All are beyond themarket capability of most testing organizations. However, large projects may realizesignificant benefits if properties of concrete from testing of large specimens can bedetermined.This paper will provide guidelines for when large specimen testing may be advantageous.It will also provide recommendations on practical measures to implement whenorganizing such testing. The presentation is illustrated with an example of a projectwhere production and testing of large specimens has been done. The example is from anRCC project where biaxial shear and direct tensile testing has been done. This is notintended to be a case study but a guidance document that may be applied to futureprojects.
