05/09/2018 • The F.M. varies between 2 to 3.2 for fine aggregate, between 5.5 to 8 for coarse aggregate and between 3.5 to 6.5 for all in aggregate. • The objective of finding F.M. is to grade the given aggregate for the required strength and workability of concrete mix with minimum cement.

Aggregate Crushing Value Test Significance & Test

So the aggregates must be tested to know its crushing strength against compressive load, whether it is suitable or not for road construction. Test precautions . The sample should be free from dust and other impurities. Wear safety gear while executing the test. Ensure the calibration of the compression testing machine. The equipment should be clean before and after the test. Apparatus Required

Aggregate crushing value test Step by Step Procedure

It is recommended that the crushing value of aggregate should be less than 30%. If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is less than 30% can be used for cement concrete road. The aggregate whose crushing value is

The tests for Aggregate Crushing Value (ACV) and FACT (10% Fines Aggregate Crushing Test) measure the crushing strength of broken rock. These results do not necessarily relate to the flexural or compressive strength of concrete made with that aggregate, but are a useful index of overall quality. Normal values for ACV range from 14 to 30%, and for 10% FACT from 100kN to 300kN. There is

01/12/2013 The results show that the concrete specimens with greater content of recycled aggregate have lower compressive strength. The reduction in compressive strength for 25% replacement of NCA aggregate was insignificant (2–4%). When the replacement ratio increased to 50%, the compressive strength reduction was 6–13%. Increasing the replacement ratio to more than 50% led to a non-linear
