When landfills located near populated areas started refusing broken concrete in the 1970s, the construction industry started crushing it to make aggregate for use as compactible fill. Wood and steel reinforcement were separated out, leaving aggregate that often included a mixture of concrete, brick, and asphalt, along with some dirt.

Particle size distribution curves of recycled aggregates from concrete pavement crushed by jaw and impact crushers. The jaw crusher produced 85% coarse aggregates (fraction >4.8 mm), whereas the impact crusher produced 82% coarse aggregates. In both cases, the content of particles finer than 0.15 mm was less than 2% mass.
Fine aggregates were a blend of beach and crusher sands with an overall fineness modulus of 2.50. Coarse aggregate was a high strength, well shaped stone with low absorption characteristics. Table 2.2: Hardened Concrete Properties (28 days unless noted otherwise)
The S&L Crusher Plant proudly offers a versatile lineup of crushed stone products to meet the aggregate needs of any project.

In the international environment of the crusher industry, besides the traditional jaw crusher, high-efficiency and environmentally-friendly construction concrete crusher will be the trend of future development. In view of the characteristics of concrete waste, Henan HXJQ Machinery designed a concrete crushing equipment-mobile concrete crusher.
Cone crushers are compression machines that take in raw materials and reduce them in size by crushing them. A variety of industries rely on these tools, such as the concrete, aggregate, mining, coal, and natural gas industries. Inside the crusher, a piece of steel, known as the mantle, rotates eccentrically.
Aggregate. Aggregate is the most exploited material in the world. It is an important component of concrete and asphalt concrete, accounting for 70% of the volume of concrete. It can inhibit the shrinkage and cracking of concrete and enhance the strength of concrete. Aggregates are divided into natural aggregates and artificial aggregates.
Industrial Rock Crushers & Stone Crushing Equipment. The mining, aggregate and mineral processing industries often have raw materials that are larger than what they can directly use or sell to other companies.
Aggregates are generally thought of as inert filler within a concrete mix. But a closer look reveals the major role and influence aggregate plays in the properties of both fresh and hardened concrete. Changes in gradation, maximum size, unit weight, and moisture content can all alter the character and performance of your concrete mix.
Rock & Aggregate Crushers. Many different industries have a solid foundation rooted in aggregates. Recognizing the extensive use of these aggregates motivates us to continuously create and improve our rock crushing equipment to help you increase production, decrease maintenance and improve the overall efficiency of your operation.
Aggregate Industries appoints ready-mixed concrete MD. UK construction materials supplier Aggregate Industries has appointed Lee Sleight as the new managing director of its ready-mix concrete division and member of the company’s executive committee. Concrete Plants, Equipment & Applications / October 19, 2021. By Liam McLoughlin.
Crushing plant aggregate is a mobile crusher utilised to extract aggregates, which is the basic material of the construction industry. The aggregate crusher crushes large stones such as granite, basalt, marble, as well as hard mines, allowing the extraction of sand, gravel and smaller crushed stones.
The products can be extracted immediately after the gyratory crusher as 0-32 mm or 0-63 mm fractions, if necessary; these materials are used when stability is needed for the given construction application. The tertiary stage produces fractions in sizes ranging from 0-2 mm to 16-32 mm. These products are used in asphalt and concrete.
In the middle part of the 2010’s, Superior launched an aggressive strategy to improve reliability and performance of the products serving the aggregate industry. Our customers — already buyers of conveyors — groaned for a better brand of service for their crushing, screening and washing equipment. Superior checked the boxes and made the leap.
For aggregate applications, we recommend the R250 to the R450, though we also offer larger crushers that are typically used in mining. No matter which model you need, you can be confident that we have engineered it to meet the most common industry concerns to give you better results.
Recycled Aggregates Recycled Concrete Aggregate (RCA) Crushed sound and clean waste concrete of at least 95% by weight of concrete with typical total contamination lower than 1% of the bulk mass. Class 1A RCA is a well graded RCA with no more than 0.5% brick content. Partial replacement (30%) for natural aggregate in concrete for sidewalks
R.R. Equipment Company has been serving the aggregate industry for over 50 years. Our vast background includes owning and operating several sand and gravel operations, quarries, trucking companies and concrete businesses.
Crushed gravel is an aggregate frequently used in construction. The stone and aggregate industry creates crushed aggregate using a lengthy process. The stone must be mined in a quarry and then transported to the rock crusher, which begins the process of crushing the larger stones into more manageable pieces.
Which Machines you chose for crushing aggregates? In crushing process, we use jaw crusher, impact crusher, cone crusher, fine impact crusher and mobile crusher as quartz stone crusher machine. These crushers and belt conveyor, vibrating screen, vibrating feeder form a complete quartz crushing plant. Of course, concrete recycling crushing

Marble dust is used as a fine aggregate in concrete. By adding 30% marble dust and 70% quarry rock dust in place of Fine aggregate in the concrete, increase in the 28-day compressive strength. As well as workability of concrete is also increased. In addition the 7 day strength also increases, so that formwork can be removed soon.
