Influence of Firing Conditions on Properties of Red Ceramic

Materials Science Forum, 2012
In the ceramic industry, the firing is one of the main stages of the production process. There are two heating rates prevailing at this stage: low heating rate (long residence time) and high heating rate (fast residence time), the low rate is more used in traditional ceramics.

Properties of Clay Ceramic Incorporated with Red Mud

Materials Science Forum, 2014
The red mud is a well known insoluble residue generated in the Bayer process to benefit bauxite ores. This residue is composed of ceramic related compounds such as iron oxide, sodium aluminum silicates, carbonates, calcium aluminates and titanium dioxide.

Microwave hybrid fast sintering of red clay ceramics

International Journal of Applied Ceramic Technology, 2021
Abstract This work aimed to examine the performance of the hybrid sintering of clay ceramic in a microwave furnace, compared to the sintering process in a conventional furnace. The raw materials were subjected to X‐ray fluorescence, loss on ignition (LOI), X‐ray diffraction, particle size distribution, real specific mass, and ...

Life Cycle Assessment Applied to Red Ceramic Bricks Production Versus Red Ceramic Bricks Incorporated with Stone Wastes: A Comparative Study

2021
Ceramic bricks play an important role in the Brazilian economy and have red clay as the basic raw material for this industry. The aim of this study was to discuss the main environmental impacts related to the manufacturing of red clay bricks, comparing the conventional production versus the production of red clay brick incorporated with ornamental ...

Degradation of Red Ceramic with Incorporated of Petroleum Waste

Materials Science Forum, 2014
The red ceramic pieces Campos-RJ degrade easily when they are in the built environment. With the intention to reduce the degradation in these pieces, was introduced petroleum coke in red ceramic. Petroleum coke is a solid fossil fuel, black in color and about granular form.

Red Ceramic Wastes: A Calcined Clay Pozzolan

2015
The properties and hydration of blended cements containing from 8 to 40 % by mass of ceramic waste (CW) from different countries (Argentine and Czech Republic) are investigated. The mini slump, the heat released rate up to 48 h, the pozzolanic activity and the compressive strength at 2, 7 and 28 are determined. Hydration process is characterized by XRD

Residual Coal Characterization for Addition to Red Clay Ceramics

Materials Science Forum, 2015
The high temperature firing to process clay ceramics requires some kind of fuel, which is associated with cost and embodied energy of the final product. Saving in fuel by introducing substances with heating power represents both economical and energetical advantages.

Industrial sewage slurry utilization for red ceramics production

Construction and Building Materials, 2014
Abstract This paper reports on ceramic materials based on hazardous industrial sewage slurry containing galvanic glass waste and clay–sand mixture. The slurry waste has high contents of heavy metals (Ni – 3.24%, Zn – 5.28%, Pb – 1.32%, Sn – 0.67%, Cr – 4.28% and Cu – 3.78%), organic components (pitches, oils, paints, inks, etc.), and water (56.35 ...

Study of Incorporation of Fuel and Fluxing Wastes in Red Ceramics

2019
Red ceramic industries are among the most important recyclers of industrial and urban wastes. The clays’ heterogeneity allows the incorporation of several types of wastes, which can be classified as fuel wastes, fluxing wastes, and property-affecting wastes.

Properties and mechanism of red mud in preparation of ultra-lightweight sludge-red mud ceramics

Journal of Central South University, 2012
New ultra-lightweight sludge-red mud ceramics (ULSRMC) were prepared by red mud (RM), clay and dried sewage sludge (DSS). The properties and mechanism of RM in the preparation of ULSRMC were discussed. The chemical components, thermal properties and mineral phases of RM were determined by energy dispersive X-ray (EDX), differential scanning calorimetry/
