    Aggregates may be produced by processing sand and gravel or by blasting and crushing bedrock materials or select byproduct materials, including recycled/reclaimed materials, such as concrete, asphalt, blast furnace slag, glass and ceramics, etc Crushed stone and processed sand and gravel are interchangeable for many applications, but not all Aggregates consisting of 100 percent crushed· What size gravel is best for concrete? The usual range employed is between 95mm and 375mm in diameter Fine aggregates are usually sand or crushed stone that are less than 955mm in diameter Typically the most common size of aggregate used in construction is 20mm A larger size, 40mm, is more common in mass concreteWhat size gravel is best for concrete?Both gravel and crushed stone are generally acceptable for making quality concrete (Photo 9), although gravel is usually preferred for exposed aggregate The use of recycled concrete, crushed to propersize concrete aggregate, has also demonstrated successful performance Recycled concrete will have a higher absorption and lower specific gravity than conventional aggregates To produce goodAggregate in Concrete Concrete Network

  • Types of Concrete Aggregate and Common Applications

    · In the production of concrete, aggregates are one of the most essential ingredients in its formation These small granular particles can be made up of crushed stone, gravel, or sand, and make up 6075% of the final concrete product’s total volume Wellmixed concrete is made up of cement and water, along with aggregates that are clean, hardAn aggregate and construction company operating quarries, sand and gravel pits, and asphalt plant and a stateoftheart ready mix concrete plant in the Owen Sound area A subsidiary of Walker Aggregates, Sutherland Construction also provides a range of roadbuilding services, commercial andAggregates | Walker IndustriesWhen the aggregate is sieved through 475mm sieve, the aggregate retained is called coarse aggregate Gravel, cobble and boulders come under this category The maximum size aggregate used may be dependent upon some conditions In general, 40mm size aggregate used for normal strengths, and 20mm size is used for high strength concrete the size range of various coarse aggregatesClassification of Aggregates Based on Size and Shape
