It is the most common stone used for concrete mixes. #10 – Crushed stone #10 is known as screenings or dust. Most use this material to create pavers and concrete blocks. Specialty Crushed Stone #57 – This category refers to a stone that is about 3/4 inch long. Most typically use it for concrete mix, landscaping, and drainage.
Sieve sizes commonly used for concrete aggregates are detailed in Table 1, and various physical properties of normalweight aggregates, with typical range values, are shown in Table 2. Coarse and fine aggregates are generally sieved separately.
Larger aggregate sizes use less cement and water. The coarse aggregate size is the primary factor affecting the strength of your concrete. In general, stronger concrete requires smaller coarse particles, with 20mm aggregates meeting the threshold for strong concrete and 40mm aggregates meeting the threshold for normal strength …
