Since 1987 would be the final year of this research project, supplementary studies on the individual topics assigned were made and compilation of the final report was done. The following were carried out as the supplementary studies on the individual assignments: (1) Method of Measuring Physical Properties of Fresh Concrete: Study on the influences of container dimensions of double-cylinder rotatin viscometers on test values. (2) Analysis of Mixing and Application: Study on the law of similitude in using large and small sizes of the same type of mixer. (3) Analysis of Vibrations and Applications: Studies on consolidation functions showing relation between total vibration energy applied to concrete and degree of consolidation, and propagation functions indicating conditions of vibration propagation in concrete.
