The result shows the concrete rebounding value, compressing strength, tensilesplittingstrength, rupture strength and elastic modulus are reduced in different degree by adding recycled aggregates.
Based on experimental data of (2) and (4), results of the statistical analysis for the relationship between compressive strength and splittingtensilestrength of RAC was given.
Discreteness of splittingtensilestrength of marble is very great and it is influenced by the factors such as heterogeneous, splitting type and size effect and so on.
