The correlation between the compressive strength and the impact crushing strength is inconsistent, and experience has shown that the impact strength is a better criterion of the actual resistance to crushing. The impact device more nearly approaches actual crusher operation, both in velocity of impact

However, the sand equivalent test can be misleading in crushed sand. For the same workability, the results indicated that there was a direct relation between water demand and the amount of materials passing No. 200 sieve for both silica and crushed sands. However, there was a good correlation between water demand and sand equivalent for only .

· Concrete is a mixture of cement, sand, and crushed rock or stone of different varieties. In the Texas area most of the crushed rock that is utilized is crushed limestone, crushed concrete, or a smooth river rock. The hardness of the stone is very important as there is a correlation between stone hardness and strength of the finished concrete.

To ensure good performance of the primary plant and prevent production losses, it is necessary to have an adequate correlation between the size of the feed material and the dimensions of the crusher feed …

The linear regression coefficient (Rc) of the correlation between UPV and compressive strength of bricks containing 80 % phosphogypsum, NHL, C and crushing sand were determined r2 = 0.907. (Figure 7). Strong correlation coefficient indicates a strong relationship between compressive strength and values of UPV bricks.

Aggregate Crushing Value (ACV) is one of the important properties of coarse aggregate. ACV gives a relative measure of resistance to crushing under gradually applied compressive load. Thus ACV is inversely related to strength of coarse aggregate. In concrete pavement design ACV of coarse aggregate is given much importance.

The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, and .
