In recent years, there has been an increasing trend towards the use of industrial waste materials for sustainable development. Sustainability helps the environment by reducing the consumption of non-renewable natural resources. Fly ash is a waste material obtained from thermal power plants during combustion of pulverized coal. This paper presents the summary of review from previous researcher in relation to the effect by used of sintered fly ash aggregate to produce structural lightweight concrete. It discussed about the element parameters of the aggregate such as physical properties of fly ash as well as binders, the palletization parameters and its influence on the aggregate properties. Also, this paper reviewed about the physical properties of the sintered fly ash aggregates have been also briefed. Sintered fly ash aggregate concretes have the 28-day compressive strengths in the range of 27–74 MPa, with densities in the range of 1651–2017 kg/m3. The durability properties of the fly ash aggregate concretes indicate that the performance is satisfactory for structural applications. Thus, this paper demonstrates that sintered fly ash aggregate concrete is one of the potential materials for the development of structural concrete.
