What are the different types of raw materials for cement?

Basic ingredients for cement are water, limestone and clay. However, cement, as well as related building materials such as mortar and concrete, may also contain other basic ingredients such as sand, slate and iron ore, which may also contain traces of aluminum. Where the raw materials for cement mix in an environment that often drops below the water point at 32 ° Fahrenheit (0.0 ° Clius), it is common to add salt or sodium chloride and possibly calcium chloride to reduce the water freezing point. Although the cement will even be set below the freezing point, it may take longer, which can contribute to the structural weaknesses in the final product. Since 2011, industrial by -products have also been added to the cement mixtures. Add beneficial properties to the cement mixture. The cement itself is a raw material for concrete, which consists of cement and a mixture of fine and fine units such as gravel, slate or pebbles with water and air mixed. Replacing industrial by -products for cement and beton include Flys, silica and blast furnaces.

Fly ASH is a type of waste product produced during many types of industrial combustion processes. It consists of fine air ash particles along with some particles of solid fuel that can be obtained from chimney washing machines. It is considered to be a useful reinforced compound in the produced rock and brick materials such as concrete, and can replace the cement at 25% of up to 70%.

Another of the key industrial by -products used in cement production is silica, which is used as a 10% replacement compound for cement. It consists mainly of the powder mixture of silica oxide and is relatively new to the construction industry. Although the production of concrete and cement was a practice from at least 2,500 BC, the use of silica oxide has only been widely incorporated into the raw materials only from the beginning of the 70s. It's because it's uniquely generatedMaterial, which is definitely different from fused silica and is a by -product of industrial activity in electrical arc furnaces. The passage of increasingly stricter environmental regulations in the US and Europe over the age of 70 has led manufacturers to recover silica as a by -product and Norway was the first nation to find use except for dumps.

The explosions are also another important component that is located when buying raw materials for cement. It is often referred to as GGBFS brushes and replaces cement in concrete at the same levels for which Flying is used, usually in 25%, 50%or 70%mixtures. GGBFS is a by -product of steel and iron furnace industry and is known to extend the life of buildings from 50 to 100 years when using. Incorporation of GGBFS since 2011 to cement has been widely applied in Asian countries such as Japan and Singapore, as well as in Europe, with a more limited use for product in the US BETon production.
