Abstract: In order to research that statics properties of concrete cylinder sample are

influenced by micro-concrete material heterogeneity, by random aggregate models generated by

different random number were established. By fixed aggregate size and constantly changing of

the sample size, the concrete numerical model was simulated and Strength change of concrete

samples was analyzed.So that strength influence of the aggregate location of the concrete

random sample was study. Calculation shows that: the strength of concrete has been little effect

by the aggregate random location, the size effect on concrete has been changed regularly, with

the size effect ratio coefficient of aggregate and sample gradually increasing, the error square

sum of strain was reduced and the brittlness of the samples becomes obvious. © (2012) Trans
