BS 812110:1990: Testing aggregates. Methods for determination of aggregate crushing value (ACV) BS 812111:1990: Testing aggregates. Methods for determination of ten per cent fines value (TFV) BS 812112:1990: Testing aggregates. Method for determination of aggregate impact value (AIV) BS 812113:1990: Testing aggregates.
The percentage mass of fines (passing a BS test sieve) formed in the test is known as the aggregate impact value AIV. higher values are given by weaker materials. For the majority of aggregates the impact value and the crushing value are similar, but brittle materials such as flints yield impact values which are about 5 units higher than ...
Oct 04, 2019 · At the end of an 8 hour shift, cone 2 has put 480 more tons of material on the ground. Assuming a per ton value = 2,400 more saleable product in one day =12,000 more a week =48,000 more a month =288,000 in six months . This is at 5/ton. Value could easily be doubled depending on what the finished product is.
This article will identify the different tests that are conducted on aggregates based on the requirements of ASTM C33 Standard Specifiions for Concrete Aggregates. It will also explore the significance of each test, as well as the corresponding ASTM test method, and the impact the test results have based on the quality of concrete. Analysis of test methods is not included in .
Mechanical Properties of Aggregates Aggregate Crushing Value Test (BS:812, part 3) Procedure • The material to be tested should pass a mm (1/2 in.) sieve and be retained on a 10 mm (3/8 in.) sieve. • Dry the sample in an oven at 100110 0 C for four hours. • Place the sample in a standard cylindrical mould and tamp it. • Put a plunger on the top of the .
