\n– Measures the hardness and durability of aggregates.
\n– Helps assess the suitability of aggregates for use in road construction and concrete works.
\n– Ensures compliance with Philippine construction standards (e.g., DPWH, ASTM, or BS).<\/p>\n
The Aggregate Crushing Value (ACV) Test is a standard method used to determine the resistance of coarse aggregates to crushing under gradually applied compressive load. In the Philippines, this test is commonly conducted following British Standard (BS 812-110:1990) or ASTM C131\/C131M-14 standards, depending on project specifications.<\/p>\n
Purpose of ACV Test
\n– Measures the hardness and durability of aggregates.
\n– Helps assess the suitability of aggregates for use in road construction and concrete works.
\n– Ensures compliance with Philippine construction standards (e.g., DPWH, ASTM, or BS).<\/p>\n

Apparatus Required
\n1. Steel Cylinder (150 mm internal diameter, height ~130\u2013140 mm)
\n2. Plunger (flat-faced, 150 mm diameter)
\n3. Compression Testing Machine (capable of applying 400 kN load)
\n4. Weighing Balance (accuracy \u00b10.1 g)
\n5. IS Sieves (12.5 mm & 10![\"aggregates](\"\/img\/c4.jpg\")
for grading)
\n6. Tamping Rod (16 mm diameter, 600 mm length)<\/p>\n
—<\/p>\n
Test Procedure
\n1. Sample Preparation
\n – Sieve aggregates through 12.5 mm and retain on 10 mm sieve.
\n – Fill the steel cylinder in three layers, tamping each layer 25 times.
\n – Level the surface and weigh (Weight A = Mass of aggregate in cylinder).<\/p>\n
2. Compression Test
\n – Place the plunger on top.
\n – Apply a gradual load at a rate of 40 kN\/min until reaching 400 kN.
\n – Hold for 10 seconds, then release.<\/p>\n
3. Sieve Crushed Material
\n – Remove crushed aggregate and sieve through a 2.36 mm sieve.
\n – Weigh the material passing (Weight B = Mass of crushed fines).<\/p>\n
4. Calculate ACV (%)
\n \\[
\n \\text{ACV} = \\left( \\frac{\\text{Weight B}}{\\text{Weight A}} \\right) \\times 100
