2020-10-14 structural lightweight concrete are prepared with manufactured aggregates made of by-products, e.g., sintered fly ash, blast furnace slag, or recycled glass. Secondly, the better thermal insulation of LWAC promotes a lower energy consumption, resulting from heating and air conditioning during building operations.

2017-11-15 Compared to cold-bonded aggregates, the sintered fly ash aggregate exhibited superior compressive strength . Concrete produced with sintered aggregates without pelletization process shows higher strength than the granite aggregate concrete having similar composition . These observations reveal that strength of the LWA is not the only factor that governs the strength properties of LWAC.

Sintered Fly Ash L. JOHN MINNICK, G. and W. H. Corson, Inc., Plymouth Meeting, Pennsylvania Lightweight concrete aggregate is being produced commercially from pulverized coal fly ash by several plants. The products are of good quality, although they vary somewhat with respect to shape and size. The type of fly ash used in the

2010-8-31 Sintered pelletized fly ash aggregates have been commercially produced in several industrialised countries such as the UK, USA, Japan, India, and North Europe. The manufacturing process of these aggregates requires pelletizing a mixture of the fly ash and water before sintering the pellets at 1300oC.

2017-8-11 The durability properties of concrete made with fly ash aggregate cured by different methods and found that sintered aggregates produce better strength compared to cold bondedaggregates. But foundthatthe fly ash aggregates produced by normal curing showed comparable results with the aggregates produced with other methods of curing, when the number of days of curing is increased. the properties of fly ash aggregates produced by normal cold bonding technique is discussed and compared with natural gravel. Concrete made out of these aggregates

2020-4-23 with sintered fly ash aggregates were evaluated. Mix design was obtained by the IS method for M30 grade concrete, and within the natural aggregates were replaced with 20%, 40%, and 60% amounts of SFLWA. The addition of SFLWA shows an increase in the workability of the concrete. Replacement with SFLWA increases with an increase in slump
