Black cotton soils are highly clayey soils
grayish to blackish in color. They contain montmorillonite
clay mineral which has high expansive characteristics. Black
Cotton soils have low shrinkage limit and high optimum
moisture content. It is highly sensitive to moisture changes.
While laying roads or constructing foundations, the sub grade
and its undesirable characteristics need to be modified using a
suitable stabilization technique. Stabilization involves the
methods used for modifying the properties of a soil to improve
its enginee ....etc

use of fly ash in river technical seminar

Abstract

Fly ash, also known as pulverised fuel ash in the United Kingdom, is one of the Coal combustion products, and is composed of the fine particles that are driven out of the boiler with the flue gases. Ash that falls in the bottom of the boiler is called bottom ash. Fly ash is generally captured by electrostatic precipitators or other particle filtration equipment before the flue gases reach the chimneys of coal-fired power plants, and together with bottom ash removed from the bottom of the bo ....etc

Abstract

This study presents an experimental study on self-compacting concrete (SCC) with two cement content. The work involves three types of mixes, the first consisted of different percentages of fly ash (FA), the second uses different percentages of silica fume (SF), and the third uses a mixture of FA and SF. After each mix preparation, nine cylinder specimens are cast and cured. Three specimens are cured in water for 28 days, three specimens are cured in water for 7 days, and three specimens are left in air for 28 days. The slump and V-fun ....etc

Geopolymers are inorganic, typically ceramic, materials that form long-range, covalently bonded, non-crystalline (amorphous) networks . Obsidian is an example of naturally-occurring geopolymer. Commercially produced geopolymers may be used for fire- and heat-resistant coatings and adhesives, medicinal applications, high-temperature ceramics, new binders for fire-resistant fiber composites, toxic and radioactive waste encapsulation and as cementing components to make concrete. The properties and uses of geopolymers are being exp ....etc

copper slag concrete ppt

Abstract

This paper reports on an experimental program to investigate the effect of using copper slag as a replacement of sand on the properties of high performance concrete (HPC). Eight concrete mixtures were prepared with different proportions of copper slag ranging from 0% (for the control mix) to 100%. Concrete mixes were evaluated for workability, density, compressive strength, tensile strength, flexural strength and durability. The results indicate that there is a slight increase in the HPC density of nearly 5% ....etc
