Vanadium staining in fired clay bricks

British Ceramic Transactions, 2003
Abstract This paper reports on a series of efflorescence tests and instrumental techniques that have been used to determine the nature and mechanism of vanadium staining, and the effects of additions of magnesite, calcite, and fluorspar to the brick mix to eliminate the problem.

Use of TEOS for fired-clay bricks consolidation

Materials and Structures, 2013
Ethyl silicate (tetraethylorthosilicate, TEOS) is one of the most used consolidants for natural stones in the restoration of architectural and cultural heritage and the literature concerning its performance in this application is quite abundant. In this paper, the need, and sometimes urgency, of preserving ancient fired-clay elements (bricks and ...

Solar conduction heat transfer in fired clay bricks

Solar Energy Materials and Solar Cells, 2005
When somebody is interested in building a house in the year-round-hot and humid regions, faces with the decision of using modern construction block material or the traditional red fired clay brick material. We performed mechanical and thermal controlled measurements on walls made using both materials.

Recycling cigarette butts in lightweight fired clay bricks

Proceedings of the Institution of Civil Engineers - Construction Materials, 2011
Several trillion cigarettes are produced worldwide annually, resulting in tonnes of cigarette butt waste. Cigarette butts accumulate in the environment due to the poor biodegradability of the cellulose acetate filters. Results from a study on recycling cigarette butts into fired clay bricks are presented. Five different soil–cigarette butts mixes with

Neutron radiography determination of water diffusivity in fired clay brick

Applied Radiation and Isotopes, 2009
The real time neutron and gamma radiography station at Maria reactor, Institute of Atomic Energy, Swierk, Poland, was used to investigate the isothermal water absorption into fired clay brick samples. The investigated brick is different from the bricks reported in El Abd and Milczarek [2004.

Investigation of kinetics of Cr(VI)–fired brick clay interaction

Journal of Hazardous Materials, 2011
Fired brick clay is an excellent sorbent for the removal of heavy metal ions from waste water, owing to the availability of pores and interlayer spacing. Consequently, heat treatment of brick clay significantly affects the extent of interaction between the brick clay sorbent and adsorbates.

Kinetics of Long‐Term Moisture Expansion in Fired‐Clay Brick

Journal of the American Ceramic Society, 2011
Slow, progressive moisture expansion is a general feature of fired‐clay ceramics. In masonry structures, it may produce cracking and must be allowed for in design. Expansion continues indefinitely although at a diminishing rate. Using long‐term data from four sources and extending up to 58 years, we show that a (time)

Fire resistance of fired clay bricks–fly ash composite cement pastes

Ceramics International, 2012
Abstract This work aims to study the effect of substitution of fly ash for homra on the hydration properties of composite cement pastes. The composite cements are composed of constant proportion of OPC (80%) with variable amounts of fly ash and homra.

Potential Of Fired Clay Bricks Produced From Aponmu Clay Deposits

Journal of the Nigerian Association of Mathematical Physics, 2013
The potential of fired clay obtained from Aponmu river, Ondo State. Nigeria for brick production have been investigated. Properties of produced bricks investigated was compressive strength, density and water absorption. The results shows that the Compressive strength, density and water absorption values ranged from 2.48 to 3.69 N/mm2 , 1340kg/m3 to ...

Recycling cigarette butts in fired clay bricks

Worldwide, cigarette butts (CBs) are among the most common type of litter. The United States Department of Agriculture estimates that in 2004 over 5.5 trillion cigarettes were produced in the world. This is equivalent to an estimated of 1.2 million tonnes of cigarette butt waste per year.
