### Compressive Strength of Concrete

Compressive strength is often used a proxy for other strength parameters as the compressive strength test of concrete is much easier and cheaper to complete than tensile strength test or the flexural strength test. This is common practice for concrete pavements and other concrete components which rely on the flexural strength of the concrete. Obtener precio

### Hardened Concrete

In a normal strength concrete, the mismatch in properties at the interface of the paste and aggregate is large. As a result, microcracks initiate in the interfacial zone at very low load levels (as a result of the load being concentrated around the areas of high stiffness, i.e. the aggregates). These microcracks propagate further into the mortar, localize, and lead to the ultimate failure of Obtener precio

### COMPRESSIVE STRENGTH OF NORMAL STRENGTH CONCRETE

In normal strength concrete, the micro cracks form when the compressive stress reaches until 40% of the strength. The cracks interconnect when the stress reaches 80-90% of the strength. The fracture surface in NSC is rough. The fracture develops along the transition zone between the matrix and aggregates. Fewer aggregate particles are broken.
