Use of Slag/Sugar Cane Bagasse Ash (SCBA) Blends in the Production of Alkali-Activated Materials
Blast furnace slag (BFS)/sugar cane bagasse ash (SCBA) blends were assessed for the production of alkali-activated pastes and mortars. SCBA was collected from a lagoon in which wastes from a sugar cane industry were poured. After previous dry and grinding processes, SCBA was chemically characterized: it had a large percentage of organic matter (ca. 25%). Solutions of sodium hydroxide and sodium...
متن کاملAdsorptive Removal of Chromium (VI) from Aqueous Solutions by using Sugar and Distillery Waste Material
Raw bagasse, Bagasse fly ash and distillery sludge, the waste generated in sugar mills and distillery have been used as lowcost potential biosorbent for the removal of hexavalent chromium from an aqueous solution. The effect of hydrogen ion concentration, contact time, adsorbent dose, initial concentrations of adsorbate and adsorbent dose on the uptake of chromium were studied in batch experime...
متن کاملIncorporation of sugarcane bagasse ash waste as an alternative raw material for red ceramic (Incorporação de resíduo de cinzas de bagaço de cana-de-açúcar como uma matéria-prima alternativa para cerâmica vermelha)
The sugarcane industry generates huge amounts of sugarcane bagasse ashes (SCBA). This work investigates the incorporation of a SCBA waste as an alternative raw material into a clay body, replacing natural clay material by up to 20 wt.%. Clay ceramic pieces were produced by uniaxial pressing and fired at temperatures varying from 700 to 1100 oC. The technological properties of the clay ceramic p...
متن کاملMECHANICAL AND CHEMICAL PROPERTIES OF SiO2-Al2O3-CaO-MgO (R2O) GLASS CERAMICS IN THE PRESENCE OF VARIOUS NUCLEATING AGENTS
Abstract: The application of inexpensive materials such as copper, zinc, lead, iron and steel slag in manufacturing of glass and glass-ceramic products in construction industry, lining materials as anti-corrosion and anti-abrasion coatings in metals and etc, has led to considerable progress in glass technology in recent years. The composition of slag glass-ceramics is mainly located in the ...
متن کاملProduction of glass-ceramic from incinerator fly ash
Vitrification is one of the technological options for treating toxic waste. This paper reports the results of the feasibility study of utilizing fly ash from municipal waste incinerators by powder sintering technology. This process was used to transform vitrified incinerated fly ash into a CaO–Al2O3–SiO2 system of glass ceramic products. The major phase exhibited is gehlenite (Ca2Al2SiO7), whic...
