Concrete is that pourable mix of cement, water, sand, and gravel that hardens into a super-strong building material.When used as an adjective, concrete also means solid. If you’ve got concrete plans for Saturday, then you have a definite plan.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.Concrete, pattern, or shape poetry is an arrangement of linguistic elements in which the typographical effect is more important in conveying meaning than verbal significance. It is sometimes referred to as visual poetry, a term that has now developed a distinct meaning of its own.A concrete mixture ratio of 1 part cement, 3 parts sand, and 3 parts aggregate will produce a concrete mix of approximately 3000 psi. Mixing water with the cement, sand, and stone will form a paste that will bind the materials together until the mix hardens.Another “old rule of thumb” for mixing concrete is 1 cement : 2 sand : 3 gravel by volume. Mix the dry ingredients and slowly add water until the concrete is workable. This mixture may need to be modified depending on the aggregate used to provide a concrete of the right workability.Aggregate consists of large chunks of material in a concrete mix, generally a coarse gravel or crushed rocks such as limestone, or granite, along with finer materials such as sand. Cement, most commonly Portland cement, is associated with the general term “concrete.”Reinforcement is often included in concrete.Cement is mainly used as a binder in concrete, which is a basic material for all types of construction, including housing, roads, schools, hospitals, dams and ports, as well as for decorative applications (for patios, floors, staircases, driveways, pool decks) and items like tables, sculptures or bookcases.Advantages of Reinforced Concrete. Reinforced concrete has a high compressive strength compared to other building materials. Due to the provided reinforcement, reinforced concrete can also withstand a good amount tensile stress.The reinforced concrete building system is more durable than any other building system.
