GET PRICEThe aggregates used in the production of concrete are inert granular materials such as gravel, crushed stone, sand, slag, recycled concrete, and geosynthetic aggregates. The aggregates may be natural, manufactured, or recycled. The aggregates are broadly classified into two types based on the size, namely- fine aggregate and coarse aggregate.

GET PRICEConcretes in this strength range can be made using carefully selected cementitious materials, sand, 10 mm to 20 mm coarse aggregate and admixtures through the use of very low water-cement ratios (say 0.25-0.35) besides careful quality control in production. Related:- How Concrete is Made ( New Research) The fineness of cement, as well as the heat of hydration, can be used to advantage. The

GET PRICECoarse Aggregate is normally greater than 5mm. Fine Aggregate is aggregate less than 5mm. Can be a single sized material typically 20mm, 14mm, 10mm,or 7mm or a graded aggregate consisting of a blend of single sized aggregate. Concrete Aggregates are produced to Australian Standards (AS 2758) or to more specific customer requirements.
GET PRICEAggregate is a component of composite materials such as concrete and asphalt concrete. It serves as reinforcement (adding strength to the overall composite material), and for forming concrete mortar (by mixing with water, bitumen, Portland cement, lime and gypsum). It is also used as base material under foundations, roads, and railroads.
GET PRICEConcrete mix design is the process of finding the right proportions of cement, sand, and aggregates for concrete to achieve target strength in structures. So, the concrete mix design can be stated
GET PRICE11.08.2018· The usual range employed is between 9.5mm and 37.5mm in diameter. Typically the most common size of aggregate used in construction is 20mm. A larger size, 40mm, is more common in mass concrete. Larger aggregate diameters reduce the quantity of cement and water needed because of its lower Voids.
