Aggregates for Concrete Civil Engineering

Aggregates for Concrete bination of gravels or crushed stone with particles predominantly larger than 5 mm ( in.) and generally between mm and mm (3⁄ 8 in. and 11⁄ 2 in.). Some natural aggregate deposits, called pitrun gravel, consist of gravel and sand that can be readily used in concrete after minimal processing. Natural ...

Mineral and Oxide Composition of Portland Cement

The Bogue calculation of cement mineral composition. With this assumption, all of the Fe 2 O 3 is assigned to C 4 AF and the remaining Al 2 O 3 is assigned to C 3 A. This leaves a set of two linear equations to be solved for the amounts of C 2 S and C 3 S. This method is named after the cement chemist Bogue.

Concrete Composition Concrete is a mixture of aggregate and often controlled amounts of entrained air held together by a hardened paste made from cement and water. Although there are other kinds of cement, the word cement, in common usage, refers to portland cement. A chemical reaction between the portland cement and water, not drying of the ...

Chloride Content Test on Concrete Structures. Chloride content can be determined from broken samples or core samples of concrete. Primarily the level of chloride near the steelconcrete interface is of prime importance. Chloride present in concrete are fixed (water insoluble) as well as free (water soluble).

Slag is the glasslike byproduct left over after a desired metal has been separated (, smelted) from its raw ore. Slag is usually a mixture of metal oxides and silicon dioxide. However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting,...
