MIX DESIGN FOR SMALL-SCALE MODELS OF CONCRETE STRUCTURES

Abstract

An easily applied method of mix design was developed for concretes suitable for use in small-scale models of concrete structures. By use of the method, model concretes of adequate workability can be produced having compressive strengths ranging from 1,000 to more than 10,000 psi. Data on mechanical properties were collected for model concretes with portland cement and gypsum cement bases. These concretes had maximum aggregate sizes of No. 4 (suitable for many model beams and columns) and No. 30 (suitable for model slabs and shells). Compared to prototype concretes of equal compressive strength, the model concretes using approximately scaled aggregate were found to have about the same splitting-tensile strength and flexural strength, a lower elastic modulus in compression, and, generally, a higher strain at maximum compressive stress. Described in the report are techniques for the manufacture and testing of small concrete specimens. Information is given on the size of test specimen to use with a particular model as well as on the age for testing the specimen and model.
