Question

What are the disadvantages that are likely to occur if fly ash light weight concrete is ysed?

Answer 1

•

Structural lightweight concrete containing sintered fly ash lightweight aggregates were produced.

•

All the concretes have densities less than 2000 kg/m3.

•

A new mix design methodology was proposed and has the capability to produce compressive strength up to 70 MPa.

•

The obtained properties are quite satisfactory and are suitable for structural applications.
