From the experiment, we get the value is 21% and 9 % less than the requirement concrete used for wearing surface such as road work which is 30 %. Aggregate physical property must lower Aggregate Impact Value, AIV because is tougher and resistance to crushed. We can conclude that the aggregate been used are medium toughand resistant to be crash.
these properties include aggregate crushing value (acv) [41], los angeles abrasion (laa) [42] test, and the 10% fines value (tfv) [43].1) crushing value of aggregatean aggregate's...
Aggregate crushing Value (percent)=w2/w1*100 The ratio of the weight of fines formed to the total sample weight in each test is to be expressed as a percentage, to the first decimal place. Aggregate crushing Value = (WB/WA) 100 …
The results obtained show that ACV value for aggregates are 25.04%, 22.70%, 36.13%,and 37.89% for crushed granite, slag, hoggin (all-in aggregate), and river gravel respectively. This...
Calculate the dry or wet aggregate crushing value to the nearest 0,1 % as follows and report it to the nearest 0,1% on form B4/3 or a similar form. Aggregate crushing value (wet or dry) percentage (m/m) = ACV B A = x 100 where : A = mass of test sample before test.
The aggregate crushing value is found by the use of the following equation; 2.5 Aggregate crushing value (ACV) = 3.0 EQUIPMENT An open steel …
For aggregates smaller than 10 mm, a 75 mm diameter cylinder and associated equipment is available. UTA-0630 and UTA-0640 Test Sets are also used for the Ten Percent Fines Value (TFV) of aggregates according to BS 812:111. The Aggregate Crushing Value (ACV) Set is supplied complete with; Cylinder Base Plate Plunger Cylindrical Measure Tamping Rod
To determine the aggregate crushing value 2 APPARATUS i. ACV machine2. ii. Plunger iii. Cylinder iv. Bass Plate v. Container vi. Tray vii. Balance 4 DISSCUSSION From the data of ACV we got 84% For strong aggregate, crushing value should be low. For surface courses this value should not exceed more than 30% and for courses not more than 45%.

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 …
The aggregate crushing value is a value which indicates the ability of an aggregate to resist crushing. The lower a figure the stronger the aggregates that is the greater its ability to resist crushing. 2.1 THEORY Granular base layers and surfacing are subjected to repeated loadings from truck tires and the stress at the contact points of ...
These tests are a measure of the crushing properties of aggregate and use the same basic equipment. The ACV test requires a standard load of 400 kN to be applied over a period of 10 minutes while the TFV test measures the force required to produce a specified depth of plunger penetration. 150mm Aggregate Crushing Value Apparatus.
Load required for 10% fines = 14x / (y + 4) x = load in tones y = mean percentage fines from two tests at x tone load. Report The load required to produce 10% fines is reported to the nearest whole number for loads of 10 tones or more, the nearest 0.5 tones for loads of less than 10 tones. Safety & Precautions
