All about Flexible Concrete or Bendable Concrete

2017/04/01 · Concrete is widely used in today’s construction industry. It has good load bearing capacity. It can take the compressive load very effectively. But the main problem with the traditional concrete is that it cannot take much tensile stresses. It fails under the tensile load. The flexible concrete is a good substitute for this problem.

The properties of hardened concrete - planete-tp : All

Hardened concrete has a number of properties, including: Mechanical strength, in particular compressive strength. The strength of normal concrete varies between 25 and 40 MPa. Above 50 MPa, the term High Performance Concrete is used (50 MPa corresponds to a force of 50 tonnes acting on a square with sides of ten centimetres).

Use of waste rubber tyres as aggregate in concrete

conventional concrete was undertaken in three phases. In the first phase, fine rubber tyres aggregates were used to replace 50% of the normal sand. This replacement was done to check the influence of the fine rubber tyres in the behaviour of the normal concrete. The second phase consisted of 50% replacement of normal gravel by coarse rubber tyres.
