In the brewing process, kieselguhr performs as a filtration medium and one generated by-product is a sludge containing kieselguhr, which is mainly composed of fragmented diatom frustules associated to organic material retained during the clarification process. The physic-mechanic tests were performed on assemblages with brick composition and brewing spent kieselguhr containing 3, 9, and 15 wt% incorporation levels of sludge, being extruded and dried (105°C) before being submitted to slow firing… 
Spent Brewery Grains for Improvement of Thermal Insulation of Ceramic Bricks
AbstractOne by-product of the brewing process is a waste containing spent grains (barley malt and maize grits). In the brewing process, this cake is composed mainly of organic matter containing high
Suitability of Reusing the Spent Diatomaceous Earth in Brick Production: A Review
Diatomaceous Earth (DE) is commonly used as a filter material in the brewery industry. Spent Diatomaceous Earth (SDE) is an industrial waste generated after filling DE pores with impurities from
Consolidation with ethyl silicate: how the amount of product alters the physical properties of the bricks and affects their durability
We evaluated the consolidating capacity of ethyl silicate in three types of bricks fired at 800, 950 and 1100 °C. We chose two concentrations of product, at 25% and 50%, diluting the product in white
Properties and environmental impact from mosaic sludge industry incorporated into fired clay bricks
Brick is one of the most common masonry units used as building material. Due to the demand recently, different types of waste materials have been investigated to be incorporated into bricks. The
Utilization of Porcelain Tile Polishing Residue
The research focuses on the properties of by-products formed in the production of porcelain stoneware: polishing residue and residue of the mixture-preparation shop. The polishing residue consists of
Regeneration of the Brewing Spent Diatomite
Brewing spent diatomite (BSDT), a beer industrial by-product, was regenerated with calcination. The characteristics of regenerated BSDT were detected by X-ray diffraction, X-ray fluorescence,
Circular economy in the brewing chain
The main aim of this review was to check for the applicability of the concept of circular economy to brewing chain. By analyzing the beer brewing process, it was possible to identify the main brewery
Biosorption of Fe (II) from Aqueous Solution by Brewing Waste: Equilibrium and Kinetic Studies
The physicochemical analysis of surface water of Mooi and Vaal rivers network indicated that the concentration of iron was far above the required limit by the South Africa water regulation. In this


Propiedades cerámicas de las arcillas de la cantera de Asseiceira (Tomar, Portugal)
The clay mined at the Asseiceira quarry near the city of Tomar, Portugal, has traditionally been used to manufacture hollow brick. However, since an assessment has shown the ceramic properties of the

Microstructural Characterization of Fired Clay Bricks in the Chontalpa Region, Tabasco, Mexico
In the Mexican state of Tabasco, clay-like materials are of particular interest in the handcraft and construction industries. Combining both and due to the abundance of clay on this region, fired
The clay deposit of Vila Nova da Rainha (VNR) is included in the lithostratigraphic formation named “Argilas de Tomar”, and is located at the lower section of the Tertiary Tagus’ river basin. Clay
