3.2.5 Aggregate Crushing Value and Ten Percent Fines Value Blended Samples of MWA CA The laboratory tests are conducted and the results of the test were presented in table 15. The tests are

coarse aggregates, the variation of aggregate crushing value of different coarse aggregates, strength gain of concrete with time for different coarse aggregates and to establish a relation between aggregate crushing value of coarse aggregate and compressive strength of concrete. In the study, Portland Composite Cement (PCC) has not been used.

Dec 19, 2014 CALCULATION: • Aggregate crushing value = B/A x 100% • The result should be recorded to the first decimal place and the mean of the two results reported. • To achieve a high quality of pavement, aggregate possessing low crushing value should be preferred. 8.

“Aggregate Impact Value is an ability or toughness of aggregates which resist sudden impact or shock load on it.” Also, it can be defined as the resistance of aggregate to failure by impact load is known as the Impact Value of Aggregate.. The Characteristics of

Calculate Aggregate Crushing Value. The ratio of the weight of fines formed to the total sample weight in each test shall be expressed as a percentage, the result being recorded to the first decimal place: Aggregate Crushing Value = W B W A × 100. Where, W A is weight of surface-dry sample
