A beton mesterséges építőanyag, melynek összetevői a kavics, a homok, a cement és a víz. Erősen lúgos. Előnye, hogy bármilyen alakra formázható, megszilárdulva pedig nagy szilárdságú tartószerkezetként működik. Lényege, hogy a kőszerű, szemcsés összetevőket (kavics/kőtörmelék és homok), a cement, mint „kötőanyag" víz közreműködése mellett összeragasztja.

Concrete production is the process of mixing together the various ingredients—water, aggregate, cement, and any additives—to produce concrete. Concrete production is time-sensitive. Once the ingredients are mixed, workers must put the concrete in place before it hardens.
Concrete Mix Design As Per Indian Standard Code. Concrete Mix Design. Introduction. The process of selecting suitable ingredients of concrete and determining their relative amounts with the objective of producing a concrete of the required, strength, durability, and workability as economically as possible, is termed the concrete mix design.

High-strength concrete has a compressive strength greater than 40 MPa (6000 psi). In the UK, BS EN 206-1 defines High strength concrete as concrete with a compressive strength class higher than C50/60. High-strength concrete is made by lowering the water-cement (W/C) ratio to 0.35 or lower. Often silica fume is added to prevent the formation of free calcium hydroxide crystals in the cement ...

4, meet the above conditions to save cement and reduce the cost of concrete. The strength of concrete is divided into twelve grades, such as C7.5, C10, C15, C20, C25, C30, C35, C40, C45, C50, C55, C60 and so on. The concrete mix ratio refers to the proportion of the components in concrete (cement, water, sand, and stone).
Jul 18, 2019· Posted on July 18, 2019. Concrete is a mixture of cement, gravel, sand, water and a range of aggregates. With about 10 billion tons of concrete produced every year, it is the most consumed substance in the world, second only to water.. It is also the world's most widely used material for construction – from bridges to large buildings, concrete forms the very foundation of our infrastructure.
