Abstract:

Based on the introduction of research status of similar materials commonly used in recent decades years at home and abroad, and advantages and shortcomings of these similar materials were analyzed. The physical properties of modified rubber powder cement mortar, including apparent density, uniaxial compressive strength, elastic modulus and splitting tensile strength, were studied. Variation of the physical parameters with replacement rate of rubber powder and water cement ratio was summarized, and a new rock similar material was produced. The results showed that the new rock similar material can well satisfy the requirements of similar material, and it was an ideal rock similar material and worth to be popularized in other model tests.

Key words: similarity principle, rock similar material, modified rubberpowder, mechanics test
