Water vapour permeability of clay bricks

Construction and Building Materials, 2003
The water vapour permeability of clay bricks has been experimentally measured in order to draw a representative outline of industrial products without pore-forming additives. The correlations between water vapour permeability and the main compositional and microstructural parameters of both bricks and clay bodies have been investigated.

Equilibrium Moisture Content of Clay Bricks

Key Engineering Materials, 2004
The equilibrium moisture content (MEq) of ordinary and lightweight clay bricks was measured and the correlation with the microstructure and pore morphology was investigated. The influence of the pore specific surface on the amount of moisture absorbed at equilibrium conditions, in correspondence of different relative humidity rates, was found to be ...

Sodium silicate activated clay brick

Bulletin of Engineering Geology and the Environment, 2008
The paper discusses the addition of sodium hydroxide to readily available natural materials in Senegal, in order to produce stronger and more durable bricks. The case study involves the Tchieky clays which were mixed with varying amounts of NaOH and heated at temperatures of 40, 80 and 120°C for periods of up to 60 days.

Eco-Friendly Fired Clay Bricks

2018 6th International Renewable and Sustainable Energy Conference (IRSEC), 2018
Fired clay bricks has been manufactured the same way for decades which makes it old and uncompetitive compared to other products like concrete. If they want to stay in the market for more years, researchers must improve their quality. The main objective of this work is to enhance the process of making bricks, this study aims to improve the thermal ...

Clay bricks with shred geogrids

2010 2nd International Conference on Chemical, Biological and Environmental Engineering, 2010
This session presents a survey and the performance of the role of shred geogrids in mud brick's compressive strength and a comparison of it with the normal mud bricks. Mud brick consists of clay, water and different materials. Its massive use may become an important evaluation due to its low cost and higher compressive strength compared to the concrete

Thermal Conductivity of Clay Bricks

Journal of Materials in Civil Engineering, 2004
In the present work the thermal conductivity of 29 samples of clay bricks was measured and the correlations of the thermal performance with the compositional, physical, and microstructural features of products were investigated. The results obtained directed our attention toward a better understanding of the role played by some parameters ~i.e ...

Ladle brick from semiacid clays

Refractories, 1967
The main feature of the technology developed for the production of high-density ladle brick which expands in service, made from semiacid clay from Chasov Yar and Druzhkov sources, is the regular firing cycle for the chamotte and the finished products, namely completion of firing in the temperature range in which we can guarantee sintering of the ...
