Hence the RCA is used as road construction material also. F. Slump Test: The Slump test was also conducted in

The crushing strength of the aggregate was determined using the aggregate crushing value (ACV) to PN-B-06714-40 [23], in compliance with the British Standard BS 812 [24], but with certain modifications. The aggregate sample placed in a steel cylinder 150 mm nominal internal diameter was loaded with a force of 200 kN. The …

The lower the AIV the stronger the aggregate. It is a simple, cheap test giving precise results. An AIV less than 30 is usually required. Aggregate Crushing Value (ACV) – this is the measurement of the resistance of aggregate to crushing by compressive force. A test specimen (10-14mm) is compressed (up to 400 kN) and the

This document gives the determination of aggregate crushing value ( ACV) of aggregates. This gives a relative measure of the resistance of the aggregate crushing under the …

The aggregate crushing value test (ACV, BS 812-Part-110) is one of the test methods for determining the crushing resistance of the aggregates. Alvarado et al. and Reyes et al. concluded that the ACV test was practical, reproducible, and stable and is a pivotal method in the evaluation of aggregate crushing resistance.

The crushing strength of an aggregate was determined by means of the so-called aggregate crushing index according to PN-B-06714-40 [19], analogous to the British method of determining aggregate crushing value (ACV) according to BS 812 [18], but with some differences. A specimen of aggregate in a steel cylinder with an internal diameter …

The aggregates crushing value test should be performed as per IS code 2386 Part IV. First, fill the sample aggregate with one-third of the cylindrical measure in three layers. Each layer should be tamped 25times freely. After filling the sample aggregate, weigh and record it as W1. Now fill the aggregate in the mould along with the plunger on top.

1. objective. The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. With aggregate of aggregate crushing value 30 or higher, the result may be anomalous, and in such cases the ten percent fines value should be determined instead.

Maximum limit of few mechanical tests for satisfactory condition of rock aggregate [10]. Sr. No. Name of Test Max. permissible limit 1 Aggregate Crushing Value (%) 30 for wearing surfaces and 45 other than wearing surfaces 2 Aggregate Impact Value (%) 30 for wearing surfaces and 45 other than wearing surfaces 3 Aggregate Abrasion …

getting reproducible results. On the contrary, the aggregate crushing test is simple, rapid and gives fairly consistent results. Application of Aggregate Crushing Test: The aggregate crushing value is an indirect measure of crushing strength of the aggregates. Low aggregate crushing value indicates strong aggregates, as the crushed fraction is low.

Procedure of Aggregate Crushing Value Test:-. Sieve the test material through 12.5 mm and 10.0 mm IS sieve. Take test samples of aggregates passing through 12.5 mm IS sieve and retained on 10 mm IS sieve (minimum 3 Kg). Dry theme in an oven for 4 hours at a temperature of 100 °C to 110 °C and then cool at room temperature.

Calculation The aggregate impact value is expressed as the percentage of the fines formed in terms of the total weight of the sample. Let the original weight of the oven dry sample be WI g and the weight of fraction passing 2.36 mm I~ sieve be W 2 g. 8. 100 W~ Aggregate impact value = --- percent.
