Compression Tests on Hardened Concrete

For the compression test, the load capacity has to be very high (300,000 lbs or 300 kips or more) in order to test high strength concretes, as the 12 in. cylinders have an area of 28.2 in. 2, and concrete strengths can range up to 20 ksi in practical applications.

Understanding comminution: Compression versus impact …

Compression crushers such as cones and jaw crushers normally have lower reduction ratios than impact crushers like a horizontal or vertical impact crusher. However, they …
