Recycling and recovery routes for incinerated sewage sludge ash (ISSA): a review.
TL;DR: The authors in this article reviewed the drivers for increasing incineration of sewage sludge and the characteristics of the resulting incinerated sludge ash (ISSA) and concluded that ISSA has significant potential to be used as a secondary source of phosphate for the production of fertilisers and phosphoric acid.

Technological and Environmental Behavior of Sewage Sludge Ash (SSA) in Cement-based Materials
TL;DR: In this article, the physical, chemical and mineralogical characteristics of SSA, and the evaluation of its use in cement-based materials, are presented in order to compare the residue used in this study with others included in the same category.
Journal ArticleDOI
Sewage sludge ash characteristics and potential for use in concrete
TL;DR: Sewage sludge ash (SSA) use in concrete related applications is assessed through systematic review involving analysis and evaluation of the global literature found published since 1983 as mentioned in this paper The material characteristics indicate potential for various applications: in small dosages as raw feed in Portland cement production, as fine and filler aggregates, or in ground form as cement component, with manageable effects on performance using manufactured SSA aggregate.

Assessment of Pb-slag, MSWI bottom ash and boiler and fly ash for using as a fine aggregate in cement mortar.
Nabajyoti Saikia,Geert Cornelis,Gilles Mertens,Jan Elsen,Koenraad Van Balen,Tom Van Gerven,Carlo Vandecasteele +6 more
TL;DR: Three types of wastes, metallurgical slag from Pb production (SLG), the sand-sized fraction of MSWI bottom ash from a grate furnace (SF), and boiler and flyAsh from a fluidised bed incinerator (BFA), were characterized and used to replace the fine aggregate during preparation of cement mortar.

Use of incinerator bottom ash in concrete
TL;DR: In this paper, bottom ash was used as an alternative aggregate for the production of building concrete with a characteristic 28-day compressive strength of 25 MPa, which is higher than natural gravel.
Journal ArticleDOI
Mechanical properties and durability of concrete made with blended fly ash
TL;DR: In this article, the effects of blended fly ash on mechanical properties and durability of concrete were evaluated using two reference mixtures, one was a mixture without fly ash, and the other contained 35% ASTM Class C fly ash.
Journal ArticleDOI
Mechanical behavior of mortars containing sewage sludge ash (SSA) and Portland cements with different tricalcium aluminate content
TL;DR: In this article, the influence of sewage sludge ash (SSA) on cement mortars strength has been studied, and the results show that SSA behaves as an active material, producing an increase of compressive strength compared to control mortar.

Compressive strength of municipal sludge ash mortars
Javed I. Bhatty,Kenneth J. Reid +1 more
TL;DR: In this article, a comprehensive test program was developed to examine the potential for using the ash as a fine aggregate in mortar, and the strength characteristics of mortars prepared from sludge ash with addition of fly ashes (both classes C and F) and varying amounts of cement and lime were cured under standard laboratory conditions for periods of 1, 3, 7, 14, and 28 days before testing for compressive strength.
