T1 - Recovery of phosphorus and aluminium from sewage sludge ash by a new wet chemical elution process (SESAL-phos-recovery process) N2 - The potential of a new wet chemical process for phosphorus and aluminium recovery from sewage sludge ash by sequential elution with acidic and alkaline solutions has been investigated: SESAL-Phos (sequential elution of sewage sludge ash for aluminium and phosphorus recovery). Its most innovative aspect is an acidic pre-treatment step in which calcium is leached from the sewage sludge ash. Thus the percentage of alkaline soluble aluminium phosphates is increased from 20 to 67%. This aluminium phosphate is then dissolved in alkali. Subsequently, the dissolved phosphorus is precipitated as calcium phosphate with low heavy metal content and recovered from the alkaline solution. Dissolved aluminium is recovered and may be reused as a precipitant in wastewater treatment plants.

T1 - Novel lightweight aggregates from masonry rubble N2 - Most lightweight aggregates (LWA) are produced by thermal Treatment of natural raw materials such as clay and shale. In addition to the high energy costs thereby incurred, the availability of suitable raw materials is limited. Other LWA manufactured from industrial by-products and wastes do not always meet the quality criteria for use in high-Quality lightweight concrete. A real alternative is the use of novel lightweight aggregates (referred to as LWA, aggregates and granules) made from mineral construction and demolition waste. An appropriate manufacturing technology has recently been developed in the framework of a German research project /1, 2/. Masonry rubble of variable grain size containing different amounts of brick material (25 to 70 %) serves as raw material. The LWA are obtained in a multistage manufacturing process by a thermal or hydrothermal treatment, which causes the expansion and the hardening of the material. The novel LWA meet the acceptance criteria for conventional lightweight aggregates. They are suitable for the production of lightweight concrete /2-6/. However to create tailor-made LWA from masonry rubble, the novel expanded materials and the influence of manufacturing conditions have to be understood in more detail. This paper reports on ongoing investigations of the chemico-mineralogical composition and microstructure of the novel LWA and focuses on the results of Chemical analyses, XRD, ESEM, TG/DTA and fusibility tests.

T1 - Synthese hydraulischer Phasen in Papierasche und Braunkohlenflugasche durch hydrothermale Behandlung N2 - Reststoffe aus industriellen Filter- und Verbrennungsprozessen, die in ihren Hauptbestandteilen aus Si02- und CaO-reichen Mineralphasen bestehen, besitzen das Potential hydraulische Eigenschaften auszubilden. Das bedeutet, dass sie in Anwesenheit von Wasser oder alkalischen Lösungen festigkeitsbildende Phasen entwickeln. Oft bedarf es zunächst einer Aufbereitung um die hydraulischen Mineralphasen zu aktivieren. Hydraulische Phasen sind z.B. die Calciumsilikate Alit (C3S) und Belit (C2S). Sie unterscheiden sich vorrangig durch ihr Ca/Si-Verhältnis. Im Allgemeinen hydratisiert Belit langsamer als Alit und das Hydratationsprodukt weist nach 28 Tagen eine geringere Festigkeit auf. Zur Herstellung von Belit wird weniger Calciumoxid benötigt als zur Herstellung von Alit. Daher muss weniger CaC03 kalziniert werden und der C02-Ausstoß bei der Produktion verringert sich. Zur Synthese von hydraulisch aktivem Belit kann eine hydrothermale Aufbereitung dienen. Verschiedene Autoren nutzten diese Behandlung zur Aktivierung verschiedener Reststoffe, wobei sich CaO-reiche Asche aus der Energieerzeugung (z.B. Braunkohlenflugasche) als sehr geeignet erwies, Papierasche (PA) aus dem Papierrecyling besitzt ebenfalls einen hohen CaO-Gehalt und ist Bestandteil der aktuellen Bindemittelforschung auf Reststoffbasis. Die Untersuchung einer hydrothermalen Aktivierung fehlt bisher. Dieser Artikel soll einen Beitrag zur Klärung der folgenden Fragen leisten: Eignet sich Papierasche zur Belitsynthese durch hydrothermale Behandlung? Wie entwickeln sich die Mineralphasen im Vergleich zur Braunkohlenflugasche? T2 - 19.
