  • Compaction Factor Test Civil Engineering

    The compaction factor is defined as the ratio of the mass of the concrete compacted in the compaction factor apparatus to the mass of the fully compacted concrete. The standard test apparatus, described above, is appropriate for maximum aggregate sizes of up to 20 mm.

  • Compaction Factor Test: Its Apparatus & 8 Procedure Steps

    20.05.2020· The compacting factor lies between 0.8 to 0.92 for the normal range of concrete. For concrete which has low workability for which slump test is not suitable then the compaction factor test is used and this test is conducted in the laboratory. Apparatus for Compaction Factor Test:

  • Compaction Factor Test for Concrete Workability Method

    09.03.2010· The compaction factor is defined as the ratio of the weight of partially compacted concrete to the weight of fully compacted concrete. It shall normally to be stated to the nearest second decimal place. Compaction Factor Value= (W1-W) / (W2-W) Result of Compaction Factor. Compaction factor of the concrete = The Compaction factor values ranges from 0.7 to 0.95.

  • Compaction Factor Test Workability Test Of Fresh Concrete

    14.02.2017· The compaction factor for the test is calculated by dividing the value of partially compacted concrete by the value of fully compacted concrete. i.e Compaction Factor = W1/W2 Conclusion:

  • Spike's Compaction Factor Calculator

    174 行· Plug those values into the calculator and it will tell you that the compaction factor = 1.237.

  • Slump Test and Compacting Factor Test of Fresh Concrete

    25.05.2013· 4.What are the standard used in slump test and compacting factor test. Ans:- The standard used in slump test is ASTM: C143 and B.S: 1882 part 2, and the standard used in compaction factor test is IS: 1199-1959.

  • Suggested Compaction Standards for Crushed Aggregate

    Suggested Compaction Standards for Crushed Aggregate Materials Based on Experimental Field Rolling F.P. NICHOLS, Jr. and HAL D. JAMES, respectively. Highway Research Engineer, and Highway Engineer Trainee, Virginia Council of Highway Investigation and Research, Charlottesville This paper describes field studies undertaken in 1960 and 1961 for the

  • Compaction Factor Test Civil Engineering

    The compaction factor test (Powers 1968; Neville 1981; Bartos 1992; Bartos, Sonebi, and Tamimi 2002) measures the degree of compaction resulting from the application of a standard amount of work. The test was developed in Britain in the late 1940s and has been standardized as British Standard 1881-103.

  • Compaction factor test- Objective, Procedure, advantages

    The ratio of partially compacted weight to the fully compacted weight is known as the compaction factor, which is always less than one. For normal concrete, compaction factor ranges from 0.8 to 0.92. Why compaction factor test is done?

  • Lab Report for Compacting Factor Test » Civil

    The test consists essentially of applying a standard amount of work to a standard quantity of concrete and measuring the resulting compaction. The compacting factor is defined as the ratio of the weight of partially compacted concrete to the weight of fully compacted concrete. It shall be stated to the nearest second decimal place.

  • Compaction Factor Test of Concrete Procedure Lab

    Compaction factor test is more precise and sensitive than the slump test and it is particularly useful for concrete mixes of very low workability as are normally used when concrete is to be compacted by vibration. Such concrete may be consistently fail to slump. Compaction factor test was developed by Road Research Laboratory in United Kingdom.

  • Compaction of Concrete Boral

    compaction on compressive strength is dramatic. For example, the strength of concrete containing 10% of entrapped air (air voids) may be as little as 50% that of the concrete when fully compacted. Permeability may be similarly affected since compaction, in addition to expelling entrapped air, promotes a more even distribution of pores

  • Article 3 Compaction Classification rev1

    The field density is (ρfield) is measured using a nuclear gauge and then compared to the standard density obtained in the laboratory (ρlab) and expressed as a percentage of Maximum Dry Density. This is referred to as relave compacon (RC) and is calculated as RC = ρ field / ρ lab. Bulking and Shrinkage

  • How To Calculate A Compaction Test Report

    27.12.2014· Calculate the Degree of Compaction The degree of compaction is the basis and or the final acceptance once it is passed. The specification commonly says “The degree of compaction shall be not less than 95 percent of maximum dry density (MDD).”

  • Soil Compaction Test Geoengineer.org

    The type of compaction and the provided energy for a given soil volume are standard and, thus, the test focuses on the change of a sample’s moisture content to derive the optimum water content (w opt). The standard Proctor test includes a 0.95-liter volume cylindrical mold in which the soil mass is placed and compacted in 3 layers. Each layer is compressed by dropping 25 times a 2,5 kg weight falling from an


    The compaction applied to the sample is by the use of a rammer with: • Standard compaction has a drop mass of 2.7 ± 0.01 kg and equipped with a suitable device to control the height of drop to a free fall of 300 ± 2.0 mm • Modified compaction has a drop mass of

  • Compaction of Soil Process, Necessity and Theory of

    Compaction (Definition): Compaction is the process by which soil particles are packed more closely together by dynamic loading such as rolling, tamping or vibration it is achieved through the reduction of air voids with little or no change in water content of soil. In other words, compaction is the use of equipment to compress soil into smaller volume thereby increasing its dry density and improving its engineering properties. Compaction
