COMPUTER SIMULATION OF THE NEAREST SURFACE DISTANCE DISTRIBUTION BETWEEN NEIGHBOR AGGREGATE GRAINS IN CONCRETE

摘要: The nearest surface distance distribution between neighboring aggregate grains exerts significant influences on the interference interfacial transition zone (ITZ) of grains, size range original crack in concrete, as well extent influencing ring assumption central grains. However few relevant literature can be found due to difficulties (1) Extracting information by means conventional experimental methods spatial aggregates concrete; (2) Realizing desired volume fraction basis sequential random-generator modeling system. SPACE system integrated with dynamic mixing algorithm provides an opportunity generate a model concrete high aggregate. In this contribution, and were studied for assumedly Fuller-distributed minimal 1 mm.
