Cube test report

Its value increases along with the strength of cement required, as much more accuracy is required for making high strength grade mixture. SD will be less if the quality at the materials of a concrete mixture is better and if the quality is poor, the SD will be high. Thus, Standard Deviation inversely proportional to the Quality of concrete. It ...

Properties of concrete

Concrete has relatively high compressive strength (it doesn''t crack under weight), but significantly lower tensile strength (it cracks when being pulled). The compressive strength is typically controlled with the ratio of water to cement when forming the concrete, and tensile strength is increased by additives, typically steel, to create reinforced concrete.

Concrete damaged plasticity

In Abaqus reinforcement in concrete structures is typically provided by means of rebars, which are one-dimensional rods that can be defined singly or embedded in oriented surfaces. Rebars are typically used with metal plasticity models to describe the behavior of the rebar material and are superposed on a mesh of standard element types used to model the concrete.
