subject: Concrete Crushing Equipment [print this page] Concrete additives have been used since Roman and Egyptian times, when it was discovered that adding volcanic ash to the mix allowed it to set under water. Similarly, the Romans knew that adding horse hair made concrete less liable to crack while it hardened, and adding blood made it more frost-resistant.
Recently, the use of recycled materials as concrete ingredients has been gaining popularity because of increasingly stringent environmental legislation. The most conspicuous of these is fly ash, a by-product of coal-fired power plants. This significantly reduces the amount of quarrying and landfill space required, and, as it acts as a cement replacement, reduces the amount of cement required.
In modern times, researchers have experimented with the addition of other materials to create concrete with improved properties, such as higher strength or electrical conductivity. Marconite is one example.
Jaw crusher is used for coarse, medium and fine crushing towards different stones and ores with compression strength between 147-245MPa. This barite crusher is with high crushing ratio, even size, simple structure, stable running, easy maintenance and low running consumption.
Impact crusher can handle different materials with size no more than 500mm and compression strength below 360 Mpa. Because of its special and good performance, it is widely used in Concrete Crushing Equipment in fields such as highway construction, water conservancy and construction.
Hammer crusher is one of the main Concrete Crushing Equipment used for finely crushing limestone, coal and other brittle materials below medium hardness in industries such as metallurgy, construction, chemicals production and water conservancy, etc. It has features such as high ratio, high capacity and even size, etc.
