Abstract:

The overall problem of reinforced microconcrete models is examined from the point of view of clarifying the basis of model scale, aggregate gradation, size of test specimen and fabricating techniques. The problems dealt with in this report include 1 Design of control specimens - shape effect, size effect. 2 Design of the model mix - aggregate gradation, water cement ratio. 3 Testing of control specimens - strain rate, type of machine used. 4 Strength properties - unconfined compression strength, flexural strength, strength of reinforcement, bond characteristics, shear strength, Poissons ratio. 5 Fabrication of models. In addition, supplementary information is provided concerning the use of plastics as a model material for reinforced concrete, and the design of a dynamic loading machine to test small scale models.
