Main Factors

This paper describes an experimental study on the fracture toughness KIIC of pure frozen soil and the behaviour of the interface between frozen soil and concrete. A four-point bending device is used in the test. Experimental results indicate that water content and temperature are the main factors affecting fracture toughness. Within the range of the experiment, loading rate has a very slight effect on fracture toughness. Some formulae are suggested to evaluate the fracture behaviour of frozen soil.Key words: frozen soil, fracture mechanics, fracture toughness, interface.

The research on the explosive compaction of reactive powders is a hot issue. In this work, unreacted Ti-Si block with high compactness has been successfully fabricated under explosive-driven compaction process. The precursors of Ti-Si powder with different stoichiometric ratios undergo pre-compaction shaping by hydraulic press and then shock loading treatment by using low-detonation-velocity explosives of varying loading conditions. The results show that the chemical reaction between Ti and Si powders are partly initiated even under low detonation pressures, indicating extremely low reaction threshold in the Ti-Si system. Meanwhile, optimal experimental conditions are displayed as the initial pressing compactness degree of 61%, and shock pressure of 11GPa. A compactness of 97% is achieved in the synthesized Ti-Si block with the lowest reactivity.
