all the samples were obtained from aggregates produced by crushing various types of hard rock. I and other workers have found that the previous value of K = 4000 works quite well when testing aggregate from sand and gravel sources. I plotted the 10 0.000000ines values and AIV data from ...
The paper aimed to collect all available relationships and datasets from the literature that presents the relations between these different parameters - such as Aggregate Impact Value (AIV), Aggregate Crushing Value (ACV), Ten Percent Fines Value (TFV), Los Angeles Abrasion Value (LAAV)...
The result of this method is the 10% Fines Value (TFV), which is also a measure of the resistance of an aggregate to crushing under a gradually applied compressive load with the difference that the upper limit of the loading force is not fixed during this test. The procedure is repeated ...

After 30 minutes from mixing, the slump value of the abovementioned concrete mixture was about 80 mm and calcium aluminate hydrates forming compound and super-absorbent polymer according to the present invention were added in Test 10, while only super-absorbent polymer was used in comparative Test...
crushing value of spontaneous combustion gangue coarse aggregate and water - binder ratio to com-pressive strength of concrete by experiment of 16 groups spontaneous combustion gangue coarse aggregate concrete specimen.The re-gression equation about crushing value of spontaneous combustion gangue coarse ...
After the preservation, crushing, and screening steps on the dumping ground, the furnace slag is matured by stabilization to be a recycled product. However, the traditional processing mode cannot digest the free lime and magnesia into calcium hydroxide and magnesium hydroxide, leading to the expansio...
Thus the Bolomey's formula should be modified considering the effect of coarse aggregate. In this paper, effect of the replacement ratio of the recycled coarse aggregate on the crushing value of the mixed coarse aggregate and the strength of the concrete made with...
RCA replacement ratio gives a negative effect on shear strength due to the initial damage initiated in crushing process, the strength value decreases with RCA replacement ratio increases. Appropriate formula has been selected to describe the change of shear strength combined with σ/cu and ρv ...
