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

FIBRE-REINFORCED FLY ASH SUB-BASES IN RURAL ROADS

SUB-BASE COURSES AND THEIR EVALUATION

SUB-BASE IS MADE OF BROKEN STONES,BOUND OR UNBOUND AGGREGATE

SUB-BASE COURSE PRIMARILY HAS THE SIMILAR FUNCTION AS OF THE BASE COURSE AND PROVIDED WITH INFERIOR MATERIALS THAN OF BASE COURSE

THE FUNDAMENTAL PURPOSE OF SUB BASE IS TO PROVIDE A STRESS TRANSMITTING MEDIUM TO SPREAD THE SURFACE WHEEL LOADS IN SUCH A MANNER TO PREVENT SHEAR AND CONSOLIDATION DEFORMATIONS

Fly ash brick (FAB) is a building material, specifically masonry units, containing class C fly ash and water. Compressed at 28 MPa (272 atm) and cured for 24 hours in a 66 C steam bath, then toughened with an air entrainment agent, the bricks last for more than 100 freeze-thaw cycles. Owing to the high concentration of calcium oxide in class C fly ash, the brick is described as self-cementing. The manufacturing method saves energy, reduces mercury pollution, and costs 20% less than traditional clay brick manufacturing. ....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
