Concrete has been in use for over 2,000 years, yet the behavior of this common, but complex, substance is not fully understood. This gap affects standard compressive strength testing (ASTM C 39), which does not account for structural effects caused by sample geometry, size of contact surface, and intensity of surface friction at the compression interface. To assess the true compressive strength of concrete and to study the natural crack propagation within concrete materials, the conventional test method must be modified to reduce or eliminate structural effects
The failure behavior of concrete materials is not completely understood because conventional test methods fail to assess thematerial response independ...
Due to the environmental and economic benefits, biocementation resulting from a microbiologically induced calcium carbonate precipitation process is b...
