“…The bulk density of fired briquette specimens decreased with an increase in the amount of charcoal additives from 2.5% to 10%. These resulted in the bulk density ranging from 1.17 to 1.68 g/cm 3 . The apparent density decreased with charcoal addition according to the control mix.…”

Organic combustible additives are frequently used to generate porosity in fired clay bricks. This study aims to investigate the effects of charcoal addition to fired test briquettes on their compressive strength, water absorption, apparent porosity, bulk density, and apparent density. The test results indicate that the amount of charcoal additive and the firing temperature are the key factors determining properties of the test fired briquettes. The study shows that low-density, porous, and lightweight briquettes can be made from Hang Dong clay mixed with charcoal additive.

“…However, fired bricks are usually stronger than sun-dried bricks, especially if they are made of clay or clayey materials 3 . Bricks can be divided into various groups according to their main mineral composition, namely silica, zirconia, alumina, mullite, magnesite, and dolomite bricks 4 .…”

“…It is generated from logging industries and they are considered mainly as organic waste making its disposal a major source of concern for the populace. Its availability, affordability combined with its pozzolanic nature has made several researchers to explore ways of using sawdust ash in the stabilization of different soil types [19,20,21]. The findings have been encouraging and have necessitated the need to further harness its potential.…”

Black cotton soil is highly notorious for its negative effect on engineering construction either as a sub grade material or material under the foundation of buildings. The engineering properties of the soil are adversely affected by the extreme poor nature of the soil. One of such properties is the compressibility of the soil. Regrettably, little emphasis has been placed on this property of the soil. To attempt to proffer solution to this problem, this research investigated the use of sawdust ash and lime on the compressibility characteristics of the black cotton soil. This was achieved by subjecting the soil to one dimensional consolidation. Other tests such as Atterberg's limits, specific gravity and particle size distribution were also carried out on the soil sample. Sawdust ash was used as additive and it was varied in 0, 4, 8, 12, 16 and 20% by weight of black cotton soil while lime of 4% by weight of the dry soil was also added to all the mixed samples throughout the duration of the consolidation experiment after it proved to be the most effective when added initially to the black cotton soil in various percentages ranging from 0 to 10% by weight of the black cotton soil. Analysis of the results obtained from the laboratory tests conducted on the soil samples and various mix proportions show that there were significant improvements in the compressibility characteristics of the black cotton soil when a combination of 16%SDA and 4%lime of the weight of black cotton soil were added to it.

“…It is also used as insulating material. Okunade (2008) used wood ash in conjunction with sawdust as admixtures in laterite clay bricks. The main chemical components of sawdust are carbon (60.8%), hydrogen (5.2%), oxygen (33.8%), and nitrogen (0.9%).…”
