The infrastructure construction of all countries in the world cannot do without concrete aggregate, concrete products play a very important role in the process of water conservancy project, highway construction and modern city construction. Why concrete becomes themost widely used building materials in the world?
1、The mineral composition of concrete mainly includes calcium silicate and calcium aluminate, whose main elements are silicon, calcium, oxygen, iron and so on. These elements and their compounds are distributed all over the world, which is easy to collect and low cost.
2、Concrete is a mixture of pure natural materials, which has good durability to adapt to the environment of the earth.
3、Concrete has good formability, when we need various shape concrete produce, without cutting, planning, sawing, the production process is simple.
In 1900, The World Exposition demonstrated the use of reinforced concrete in many aspects, which caused a revolution in the field of building materials. In 1867,French engineer Einar BIKE saw the flowerpots, tub, and water tank made with barbed wire and concrete and then he tried to get this material used in building construction. Later, reinforced concrete has become an important material in the world landscape. Concrete products mainly include lightweight aggregate concrete, aerated concrete and various concrete admixtures. In recent years, polymer material began to enter the field of concrete material,as the building market new materials polymer concretes are gradual popular. At the same time, various forms fibers are used in the preparation of new concrete material.
Concrete is the most widely and the largest amount building material used in civil engineering. According to the predetermined performance to design and make production of concrete, lightweight, high strength and multipurpose concrete is a new direction. Making use of modern technology, we can vigorously develop new technology, new equipment. We can extensive useindustrial waste as raw materials, which is a new research on concrete products. Commodity concrete is combined with the construction process of modern concrete and advanced construction process; its popularity can represent the concrete construction and modernization level in a country. Commercial concrete is mixed with concentrated way to supply certain requirements of concrete construction site. It includes the process of mixture, transportation, pumping and pouring etc.. The only requirement of commodity concrete in market competition is to premise workability, strength and durability, of course the prerequisitesare low cost and the lowest retail price.
Concrete is composed of cement, coarse aggregate (crushed stone or gravel), fine aggregate (sand), additive and water, which is an artificial building material all over the world. Well known concrete product line mainly include crushing, milling and screening. At first, we need PEW jaw crusher, which can complete material crushing. Then we'll start mechanism sand production flow, concrete has high requirement onthe fineness of the sand. SBM VSI5X sand making machine is necessary crushing equipment which used in manufactured sand production line, sand & gravel production plant.It is the indispensable machine in sand making industry and it is also the most ideal truing machine for mining and construction industries. The third part we need grinding equipment which is used to make production of cement. After crushing, sand making and milling, the production of concrete aggregate is ready. The final step is to make lime, cement, sand, water, additives together and in accordance with a certain proportion to stir. Concrete aggregate has a very important significance for national construction andso choose a cooperation manufacturer is very critical, which can ensure the quality of concrete production.
SBM has released the K series portable crushing and screening plants, which contain 72 models that fit various crushing work in metal mines, building aggregates and solid waste treatment fields.
Jaw crusher is mainly used for crushing various ores and large materials with compression strength not more than 320Mpa.
VSI crusher is the original rock-on-rock crushing equipment used in the third of fourth stage of crushing circuits.
Magnetic separation machine can be applied for wet dressing of ores with the size less than 3mm.
HST cone crusher is a wide variety of quality size reduction equipment & system in rock processing industry.
