The Comparison of Coral Concrete and other Light Weight Aggregate Concrete on Mechanics Performance

Abstract:

The concrete which take coral fragments as aggregate can solve the shortage of building materials in the ocean reef island effectively, The coral concrete shall be classified as light weight aggregate concrete from the angle of the apparent density of building materials, its basic mechanical properties are similar to ordinary light weight aggregate, but there are also significantly different. The different between coral concrete and pumecrete、haydite concrete and the basic mechanics characteristics of coral concrete were study in this paper. The intensity、development of intensity with age、stress-strain relations、failure mode under load were discussed.
