Apr 11, 2012· A comprehensive research has been conducted to explore the influence of sintering on the properties of fly ash aggregate containing clay binders (bentonite and kaolinite). Fly ash aggregate containing clay binders, have been subjected to various sintering temperatures at different durations of 700–1400 °C and 15–120 min, respectively.
Sintered Fly Ash Lightweight Aggregate Plant With the ever increasing demand for coal as an energy source there is a growing need for disposing of the waste fly ash which results from burning coal. This problem is growing especially severe in India, where Coal-powered Power Plants provide a bulk of the electricity generation.
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 ...

2.36mm sieve. The coarse aggregate and Sintered fly ash aggregate were of size 12mm down passing. The concrete specimens were cast by replacing the coarse aggregate entirely with Sintered fly ash aggregate. The super plasticizer used was polycarboxylate ether based and basalt fibre of length 18mm was added to the concrete.
aggregate is fully replaced with Sintered fly ash aggregates. In this experimental investigation partial replacement of cement (11%)with three number of pozzolanic materials like silica fume, slag and fly ash in equal proportions along with varying percentages of Nano silicon dioxide at 0, 0.5, 1 and 1.5 on 11% of pozzolanic materials.
The sintered flyash aggregate concrete is spherical in shape, possessing 5-20 mm size and light grey colour. Water absorption is 15-20% in uncrushed material and 40-50% in crushed material; bulk density: 640-750 kg/m3, aggregate crushing strength: 5-8.5 t.
