Abstract

Results of a 2-yr study of cause-effect relationships involved in roughness of concrete pavements are reported. Data were derived both from analog traces obtained with a profilograph in each wheelpath of randomly selected pavements within hours after placement, and from qualitative observations of placement methods. Construction sampled consisted of 184 sections of one - and - two - lane pavements built under 62 different contracts with seven different form-type finishing machines and three different slip-form pavers. Statistical anal ....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

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

Reinforced concrete structures often have to face modification and improvement of their performance during their service life. The main contributing factors are change in their use of ,new design standards, deterioration due to corrosion in the steel caused by exposure to an aggressive environment and accident events such as earthquakes .In such circumstances there are two possible solutions: replacement or retrofitting.
Retrofitting of flexural concrete elements are traditionally ac ....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
