In very high-strength concrete mixtures (greater than 70 MPa) the crushing strength of the aggregate can be a limiting factor to the ultimate compressive strength. In lean concretes (with a high water-cement ratio) the crushing strength of the aggregates is not so significant.

The crushing strength of concrete, determined by breaking a cube, and often called the cube strength, reaches values of about 3 tons per square inch, that of granite 10 tons per square inch, and that of cast iron from 25 to 60 tons per square inch.

Aggregate Crushing Strength Test onlinecivilforum. Mar 27, 2019The crushing strength or aggregate crushing value of a given road aggregate is found out as per IS-2386 Part- 4 The aggregate crushing value provides a relative measure of resistance to crushing under a gradually applied compressive load

2016-06-30· The crush strength is the load (similarly measured) at which a slab of specified thickness will begin to show breakup and crushing. There is a spread between these measures. Compressive strength of a particular concrete mix might be, say, 6000 pounds. That means it will be safe to put that much load onto the pad, repeatedly.

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 under standardized conditions, and the strength of the aggregate used in road construction is expressed by numerical index.

From above table, we see that, concrete gains 16 percent strength in one day, 40 percent in 3 days, 65% in 7 days, 90% in 14 days and 99% strength in 28 days. Thus, it is clear that concrete gains its strength rapidly in the initial days after casting, i.e. 90% in only 14 days.

The Compressive Strength of Concrete determines the quality of Concrete. This is generally determined by a standard crushing test on a concrete cylinder. This requires engineers to build small concrete cylinders with different combinations of raw materials and test these cylinders for strength variations with a change in each raw material.

Crushing Strength of Aggregate: The compressive strength of concrete cannot exceed that of the aggregate used therein. Actually it is not easy to determine the crushing strength of individual particles. It is the bulk aggregate crushing strength which is determined.
