Aggregate comes in two general categories: fine and coarse. Fine aggregate tends to consist of sand, crushed stone, and gravel screenings. Fine aggregate is used when making thin concrete slabs or where a smooth surface is desired. Coarse aggregate, on the other hand, is made up of gravel, caliche, shot rock, and other coarse substances.

 — Jaw crushers and impact crushers are the most popular types of crushers. Each type has pros and cons. When thinking about gradation, the jaw crusher will most likely produce a coarser blend of material whereas the impact crusher will most likely produce a finer gradation of material with more powder and dust.

 — 2.2 Concrete Mixes and Specimen Preparations. According to ACI 211.4R [] and NBN B 15-001 [], eight concrete mixes were designed, as shown in Table 2.The moisture content of RCA was between 2.2% and 3.2%. This value is a function of the aggregate storage locations and the weather conditions on site [].A two-stage mixing …

 — In some situations, a primary crusher may be sufficient to achieve the desired product size. However, in other situations, a secondary crusher may be required to further refine the material. For example, if the primary crusher produces a coarse product, a secondary crusher may be needed to produce a finer product.

 — Concrete has become a widely used building material, with the global concrete consumption estimated to be around 14 billion cubic meters in 2020, according to statistics from the Global Cement and Concrete Association (GCCA) [].Aggregates in concrete are an essential component, constituting approximately 75% of the total …

 — The crushing of concrete generates more adhered cement paste in fRCA, resulting in higher contents of soluble alkalis and sulfates in fRCA than in coarse recycled concrete aggregates. The alkalis were shown to be less stable in adhered cement paste of fRCA, compared to alkalis contained in minerals such as feldspars [85]. Using SEM …

Jaw Crushers; Cone Crushers; Typically, the initial crushing stage is completed using either gyratory crushers or jaw crushers. It is often the case that there will be only one crusher installed, and this will be referred to as the primary crusher. Cone crushers are more often used for 2nd, 3rd & 4th stage crushing steps (although not always).

Crushing, screening, and washing may be used to process aggregates from either sand and gravel deposits or stone quarries. Aggregates ... A typical consensus specification for fine and coarse aggregate for concrete is ASTM C 33. Synthetic aggregates may be either byproducts of an industrial process, in the case of blast-furnace slag, or products of

The unit cost of concrete progressively decreases as the coarse-graded aggregate is substituted with the crusher-run and as the tailings are added. On the other hand, the compressive strength of mixtures including the crusher-run is better than that of graded coarse aggregate and is further improved by the addition of tailings.
