This fusion is uneven throughout the various forts and even in a single wall. Some stones are only partially melted and calcined. Whilst in others their adjoining edges are fused firmly together. In many instances, pieces of rock are enveloped in a glassy enamel-like coating, which binds them into a whole.

iii ABSTRACT Alkali–silica reaction (ASR) is a major concrete durability concern that is responsible for the deterioration of concrete infrastructure in the world.
Montmorillonite is a very soft phyllosilicate group of minerals that form when they precipitate from water solution as microscopic crystals, known as clay is named after Montmorillon in France.Montmorillonite, a member of the smectite group, is a 2:1 clay, meaning that it has two tetrahedral sheets of silica sandwiching a central octahedral sheet of alumina.

Cupola Furnace Slag: Its Origin, Properties and ...
· A cupola furnace is the most frequently used furnace aggregate for cast iron production. A by-product of the production of cast iron in cupola furnaces is cupola slag. Its amount is 40–80 kg per 1 tonne of the produced cast iron, and that is one of the reasons why this material is not as favoured as, for example, the blast-furnace slag. The purpose of this article is to provide the basic ...

· Pure fine sand, pyrites or any other mass containing flint is mixed with freshly calcined and crushed lime in the following proportion: 10g sand or pyrit and 1g lime. Lime is quenched by the humidity of the sand, corrodes flint and forms a thin layer around each silicon grit. Upon cooling, the mixture is softened with water.
Basalt Fiber Properties, Advantages and Disadvantages
Basalt fiber is a relative newcomer to fiber reinforced polymers (FRPs) and structural composites. It has a similar chemical composition as glass fiber but has better strength characteristics, and unlike most glass fibers is highly resistant to alkaline, acidic and salt attack making it a good candidate for concrete, bridge and shoreline structures.
