The cement head permits selective launching of darts, setting plugs, balls or other objects which can be held in place within the cement head without being damaged or washed away by slurry flow, but which can be beneficially launched into said slurry flow at desired point(s) during the cementing process.

Advertisement. Cement itself is made from calcium and silicarich materials, such as limestone and clay. Its unique adhesive properties make it an excellent binding agent, but on its own, cement is prone to cracking. Compared with concrete, which can last hundreds of years, cement is much less durable.
Cement is the binding element in both concrete and mortar. It is commonly made of limestone, clay, shells, and silica sand, with limestone being the most prevalent ingredient. These materials are crushed and combined with other ingredients (including iron ore), and then heated to about 2,700 F.
Lemon juice and the juice of sorrel will also remove ink stains, but not so easily as the concrete acid of lemons, or citric acid. The concrete is tamped, struck off to shape and smoothed with the belt at .
Some basic definitions used in cement and concrete A few useful basic definitions follow, since the meanings of the words 'cement' and 'concrete' are rather blurred in general use. Portland Cement: Material made by heating a mixture of limestone and clay in a kiln at about 1450 C, then grinding to a fine powder with a small addition of gypsum.
Concrete is made up of three basic components: water, aggregate (rock, sand, or gravel) and Portland cement. Cement, usually in powder form, acts as a binding agent when mixed with water and aggregates. This combination, or concrete mix, will be poured and harden into the durable material with which we are all familiar.

Aggregate Definition. It is defined as: "Aggregates are the inert materials that are mixed in fixed proportions with a Binding Material to produce concrete".. These act as fillers or volume increasing components on the one hand and are responsible for the strength, hardness, and durability of the concrete on the other hand.

Portland cement gets its strength from chemical reactions between the cement and water. The process is known as hydration . This is a complex process that is best understood by first understanding the chemical composition of cement.
HYDRATION OF CEMENT It is the reaction (s eries of chemical reactions) of cement with water to form the binding material. In other words, in the presence of water, the silicates (C3S and C2S) and aluminates (C3A and C4AF) form products of hydration which in time produce a firm and hard mass the hydrated cement .
What is meant by hydration of cement??.. Answer / mundhe manoj When a water is added to cement, a chemical reaction starts which exothermic in nature and produce significant amount of heat is known as hydration of cement
The hydration of cement can be thought of as a twostep process. In the first step, called dissolution, the cement dissolves, releasing ions into the mix water. The mix water is thus no longer pure H2O, but an aqueous solution containing a variety of ionic species, called the pore solution.
