From ancient days, to high-resistance through the concrete high-strength
The concrete is old
The concrete has been used since ancient times. The roman concrete to adjust it, for example, was formed by ash volcanic and hydrated lime. The roman concrete was top other recipes used by other cultures. In addition to the regular roman concrete, the The romans invented the hydraulic concrete, which is obtained from the ash volcanic and from the clay.
Concrete modern
The normal concrete is the term for the laying of the concrete that is produced by following the mixing instructions that are commonly published on packets of cement, typically using sand or other material common as the aggregate, and often mixed in improvised containers. The ingredients in a particular mixture depend on from the nature of the application. There are many types of concrete, premixed which include cement powder mixed with an aggregate, which requires only water.
Concrete high strength
The concrete high-strength has a resistance to compression more than 40 MPa (5800 psi). It defines concrete with high resistance that cement with a class of resistance superior compression to C50 / 60. The concrete high strength is obtained by lowering the ratio of cement-water to 0.35 or lower. Often fumes, silica to prevent the formation of crystals calcium hydroxide free in the cement matrix, which might reduce the strength at the bonding cement-aggregate. In some applications of concrete-high strength design criterion is the elastic modulus rather than the compressive strength of the final.
GMP spathrough a consolidated experience, and thanks to a high degree of professionalism, is a leader in Umbria in the production and marketing of concrete pre-packaged.
