"Demonstration of Utilising High Volume Fly Ash Based Concrete for Structural Application" 
by Structural Engineering Research Centre

Scope

To demonstrate the utilisation of High Volume Fly ash based concrete for structural applications through laboratory investigations.

Parameters

The following activities would be carried out to fulfil the scope of work:

• Characterisation of fly ash sample
  - Tests would be carried out to obtain Physical properties and Chemical composition of fly ash sample.

• Study the fly ash cement pastes for compatibility with chemical admixture (i.e. superplasticiser).
  - It is proposed to use two different types of superplasticisers, available in the market

• The following tests are to be carried out for the fly ash based concrete
  - Development of compressive strength at 1, 3, 7, 28, 56 and 90 days
  - Study of Chloride-ion penetrability (RCPT tests based on ASTM C 1202) at 28, 56 and 90 days.
  - Accelerated testing for corrosion of steel in concrete by impressed current method in chloride cum sulphate environment
  - Assessment of resistance to carbonation
  - Stress strain characteristics (s - e curves, and Young Modulus) and flexural strength and bond strength at 28 days for the concrete.
  - Resistance to abrasion at 28 days
  - Study of the structural behaviour of reinforced concrete structural elements, such as beam and column specimens under different static ;load conditions, viz., flexure and shear, for the beam and under compression for the column
  - Testing of typical beam-column joint under cyclic loading.
  - Preparation of technical report giving the results of carious test and recommendations.
