What is Aggregates ?

Construction aggregate , or simply ” total ” is a large class of materials used in the coarse particles buildings, including sand , gravel, crushed stone , slag, recycled concrete and geosynthetic polymerization. Aggregates are the world’s mined material . The aggregate component of a composite body of materials such as concrete and asphalt concrete ; strengthened to increase as the sum of strength to the overall composite. Due to the relatively high value of hydraulic conductivity compared to most soils , aggregates, widely used in drainage applications such as foundation and French drains , septic drain fields , retaining walls and drainage and road side edge drains. Aggregates can be used as the foundations, roads and rail base material . In other words , the aggregate as a stable foundation or road / rail base with predictable, uniform properties ( for example , to help prevent roads or buildings in solving differential ) , or as a low-cost expansion , with the more expensive combine to form cement or asphalt concrete .
The total size of the preferred bitumenous road construction EN 13043 are given as d / D ( where the minimum and maximum range Description square mesh grating , the particles can pass ) . Sizing the same category for larger armor stone dimensions meet EN 13383, EN 12620 for concrete aggregate , EN 13242 basic layer for road construction and the EN 13450 railway ballast .
In the American Society for Testing and Materials published specifications for a variety of construction aggregate products, which, by their personalized design for a detailed list of specific construction purposes. These products include specific types of coarse and fine aggregate designed for such uses additives to asphalt and concrete mixes , and other construction purposes . MOC further refinement in order to tailor the material specifications of the total demand and total supply to use its capacity in specific locations .
Sources for these basic materials can be divided into three main areas: mineral aggregate deposits, including sand , gravel and stone mining ; used by the steel manufacturing waste and recycled concrete , which itself is manufactured mainly from mineral aggregates . In addition , there are some ( small ) is used as the material of a special lightweight aggregate: clay, pumice, perlite, and vermiculite.
 
Aggregates Washing Plant

Aggregates Washing Plant is Aggregates (artificial Aggregates, Natural Aggregates) for washing equipment. Aggregates Washing Plant is widely used in gravel pits, mining, building materials, transportation, chemical industry, water conservancy and hydropower, concrete mixing stations and other industries in the washing of the material. Aggregates Washing Plant can be divided into two types: XS and XL model type. It can remove impurities covered gravel surface, while destruction of vapor-coated sand layer, in order to facilitate dewatering, play efficient sand washing cleaning action.
