Compressive Strength of Concrete Cube Test, Procedure ...
Compressive Strength = Load / Crosssectional Area. Procedure: Compressive Strength Test of Concrete Cubes. For cube test two types of specimens either cubes of 15cm X 15cm X 15cm or 10cm X 10cm x 10cm depending upon the size of aggregate are used. For most of the works cubical molds of size 15cm x 15cm x 15cm are commonly used.

Selfconsolidating concrete subjected to high temperature ...
2009121 The loss of indirect tensile strength for SCC and VC subjected to high temperatures was clearly different from the more gradual loss of compressive strength. This is because many micro and macro cracks were produced in the specimens due to the thermal incompatibility between aggregates and cement paste [29] , [34] .

Prestressed Concrete Bridge  an overview ScienceDirect ...
The prestressed concrete bridge girder shown in Fig. 6.9 spans 21.6 m and supports a superimposed dead load G of 6 kN/m and a live load Q of 20 kN/m (excluding selfweight). A 150mm thick topping slab was cast over the top flange of the beams after full stressing. The bridge is upgraded for HLPV resulting in an increase in the unfactored live loads applied to the beam.

How Is The Tensile Strength Of Concrete Measured?
2021329 Tensile strength is measured in units of force per crosssectional area (N/SQ.mm or Mpa). Testing for tensile strength can be difficult due to the material’s tendency to break or crack, and this is why tensile strength is usually measured via indirect methods rather than a direct method known as a uniaxial tensile test.
