Lightweight Aggregate Production

1-how much of the materials should be melted at the sintering temperature selected in light aggregate production(what extent should the melting minerals?(feldspars etc.), how many of them protected their solid structures(water should not exceed)) What should these values be for minimum grain density and maximum compressive strength? Which materials can be used in this sense? how lightness and strength are affected when flying ash is used?

2-What should be optimum aggregate diameter in lightweight aggregate production? how the strength is affected when the size increases? how grain density is affected when the size increases?Why is that?According to which standard to lightweight aggregate strength test?

3-What is the effect of sintering time and temperature in light aggregate production

4-What should be the most appropriate drying process in light aggregate production?Why is that? Provide information on changes in light aggregate with drying(volume,strength etc.)

Advise when a contractor will not be in breach of a construction contract as defined under the Housing Grants Construction and Regeneration Act 1996, if he wants to stop work on a project due to non-payment.

1. Circle the correct statements:

   2. Turbulent flow motion is irregular and predictable.
   3. Lagrangian flow description uses field representation of the flow.
   4. Streamlines are a series of curves drawn tangent to the velocity vectors.
   5. Equation of continuity describes the conservation of energy.
   6. In a control volume, the volume is conserved.
   7. Bernoulli equation describes the conservation of energy in a real fluid flow.
