Water absorption percent of dry weight = W B − W A W A ×100 W B W A W A × 100 % Where W A is Dry weight of aggregate The weight in g of ovendried aggregate in air W B is Weight of aggregate immersed in water The weight in g of the saturated surkedry aggregate in air Note Water absorption shall not be more than 2% per unit by weight

Recommended Values of Specific Gravity and Water Absorption for Aggregates The specific gravity of aggregates normally used in road construction ranges from about to with an average of about Water absorption shall not be more than per unit by weight Read more Specific Gravity of Fine Aggregates

A particle Size Distribution PSD test used for grading of aggregates and earthworks materials to determine suitability using Grading Limits and Coefficient of Uniformity PSD by Pipette Method sedimentation BS1377 2 & BS EN ISO 17892 4 Used in conjunction with a sieve analysis to determine the silt and clay content of a soil

100 W2 Where W1 = Total weight of dry sample Aggregate crushing value = W1 W2 = Weight of the portion of crushed material passing IS sieve Results The mean of the crushing value obtained in the two tests is reported as the aggregate crushing value Limits The aggregate crushing value for cement concrete pavement shall not exceed 30%

The aggregate crushing value is an essential index in the construction of road bases and is defined as the mass percentage of fine particles after a confined compression test of recycled CDW

19/12/2021· vi Two tests should be conducted 7 CALCULATION • Aggregate crushing value = B/A x 100% • The result should be recorded to the first decimal place and the mean of the two results reported • To achieve a high quality of pavement aggregate possessing low crushing value

04/10/2021· 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 Thus the test can be used to assess the suitability of aggregates with reference to the crushing strength for various types of pavement components

No AT 199 NAME Aggregate Impact Value Test Apparatus Quality Standard As Per IS 2386 P IV Aggregate Impact Value Test Apparatus is used for determining the aggregate impact value The Sturdy Construction consists of a base and support columns to form a rigid framework around the quick release trigger mechanism to ensure an effective free fall of the hammer during test

The test aims at looking for the forces required to produce 10% of fine values weight of fines aggregates/weight of all aggregates = 10% This test is very similar to Aggregate Crushing Test in which a standard force 400kN is applied and fines material expressed as a percentage of the original mass is the aggregate crushing value

The following description is a brief summary of the test It is not a complete procedure and should not be used to perform the test The complete flat and elongated particle test procedure can be found in AASHTO T 176 Plastic Fines in Graded Aggregates and Soils by Use of the Sand Equivalent Test; ASTM D 2419 Sand Equivalent Value of Soils
