AGGREGATES FOR CONCRETE E1-3 sieve and predominantly retained on the 75 µm (No. 200) sieve is called "fine aggregate" or "sand," and larger aggregate is called "coarse aggregate." Coarse aggregate may be available in several different size groups, such as 19 to 4.75 mm (3/4 in. to No. 4), or 37.5 to 19 mm (1-1/2 to 3/4 in.).

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.
Currently, 28-day concrete strengths ( f c ′) range from 2500 to 9000 psi, with 3000 to 4000 psi being common for reinforced concrete structures and 5000 to 6000 psi being common for prestressed concrete members. Concretes of much higher strengths have been achieved under laboratory conditions. The curves shown in Figure 1 represent the result of compression tests on 28 …

Crushed rubble can be used for road gravel, revetments, retaining walls, landscaping gravel, or raw material for new concrete.Large pieces can be used as bricks or slabs, or incorporated with new concrete into structures, a material called ...
Concept and significance of the Aggregate crushing value test. The ' aggregate crushing value test ` gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Aggregate crushing value is defined as the percentage by weight of the crushed (or finer) material obtained when the test aggregates are subjected to a specified load …

The compressive strength of the concrete cylinder is one of the most common performance measures performed by the engineers in the structural design. Here, the compressive strength of concrete cylinders is determined by applying continuous load over the cylinder until failure occurs. The test is conducted on a compression-testing machine.

A concrete crusher has cutting shears with a first cutting arm forming an additional arm on one of the jaws of the breaker tongs and a second cutting arm rigidly joined to the frame of the concrete crusher. An hydraulic piston/cylinder unit drives the jaws such that the first cutting arm is in an open position relative to the second cutting arm when the jaws are in an open position.
Concrete block often appears after building and bridge demolition, which will cause problems like pollutions and land waste. There are mainly 5 types of concrete crushers like portable concrete crusher, mobile concrete crusher, small concrete crusher, excavator concrete crusher and bucket crusher, so you have to choose the right crushing machine according to your own situation.
The crushing characteristics of hardened concrete are similar to those of natural rock and are not significantly affected by the grade or quality of the original concrete. Recycled concrete aggregates produced from all but the poorest quality original concrete can be expected to pass the same tests required of conventional aggregates.
