Furthermore the soil is compacted into five layers with 25 blows per layer. In the other hand soil compaction test is carried out in the laboratory in determining the ideal volume of water to be poured while compaction the soil on site so that the required compaction degree can be obtained.

The process which simulates the in-situ compaction processes typically performed during construction of earth dams.
. This results in higher maximum soil densities at lower optimum moisture contents. This plays a vital part in construction for soils are mainly used as supports for a lot of infrastructures. Compute the Bulk Density of Sand the starting point ton how to calculate a compaction test The calculation of bulk density of sand shall be made in the laboratory before moving on to the site.
The most common laboratory test for soil compaction is the Proctor compaction test. Grease the inner surface of the hoppers and the cylinder and fasten the hopper doors. Compaction is a process in which the soil particles are mechanically compacted to increase densities.
Here are the steps on how to calculate a compaction test or In-situ density test report. Sieve it through 20mm and 47mm sieve. PROCTOR TEST COMPACTION TEST INTRODUCTION For earthwork construction it is important to compact soils to a dense state so that the soils will attain satisfactory engineering properties.
Procedure for Compaction Factor Test of Concrete-. Several methods can be used to compact soil in the field including tamping kneading vibration and. Download View Compaction Test Report as PDF for free.
Proctor a field engineer for the Bureau of Waterworks and Supply in Los Angeles California. Lab report on Standard Proctor Compaction test. Take about 20kg of air-dried soil.
Bendigo Soil and Concrete Testing Laboratory Gate 7 Sharon Street Bendigo VIC 3550 Phone. Compaction Control Test Report Report Number. Geotechnical Lab Report 2 Geotechnical Lab Reports Proctors Compaction Test Introduction Soil compaction refers to the process whereby the soil particles of a sample are compacted using mechanical compressive means so as to increase the density of the soil.
ASTM D 1557 - Standard Test Methods for Laboratory Compaction Characteristics of Soil Using Modified Effort 56000 ft-lbsft3 2700 KN-mm3. 1 TESTS TO EXAMINE THE INFLUENCE OF MOISTURE CONTENT ON SOIL PROPERTIES THROUGH VARIOUS COMPACTIVE METHODS REPORT FROM ONLINE COMPACTION LABORATORY DEMONSTRATION PERFORMED ON 10 TH SEPTEMBER 2020 SID. This test was performed using a compaction mold that was filled with soil and then compacted three times using the standard proctor hammer.
Meld was prepared on a hard flat surface. In this test the water content. The important characteristics of.
During the laboratory test the mold is attached to a baseplate at the bottom and to an extension at the top. The most common laboratory test for soil compaction is the Proctor compaction test. Here are the values tabulated.
It is also desirable to know the optimum soil conditions for compacting a given soil. Test procedures are similar but the laboratory compactive effort of the modified method is higher. The standard proctor compaction test was first developed by RR.
The moisture content of the soil is the factor used to determine the maximum dry density of the soil sample used while. Make sure that you have recorded the method of compaction used eg Standard Proctor Method A on data sheet. The soil is mixed with varying amounts of water and then compacted in three equal layers by a hammer that delivers.
In the Proctor test the soil is compacted in a mold that has a volume of 944 cm3The diameter of the mold is 1016 mm. Proctor 1933 for assessing compacted fill and from then it became a universal standard test. The Proctor test was invented in the 1930s by R.
You may watch the video here. Calculate the percentage retained on 20mm sieve and 475mm sieve and the percentage passing 475mm sieve. Compaction reduces the voids ratio making it more difficult for water to flow through soil.
Using a 10lb 454kg hammer with 18in 4572mm free-fall instead of the 55lb 249kg hammer with 12in 3049mm drop. For each mix take 5 kg of fine aggregate 10 kg of coarse aggregate and 25 kg of cement. Compaction energy is the amount of mechanical energy that is applied to the soil mass.
If the percentage retained on 475mm sieve is greater than 20 use the large mould of 150mm diameter. This laboratory test is performed to determine the relationship between the moisture content and the dry density of soil for a specified compaction energy. Compaction test report group a1 enc211-00412018 kirui mark kiprop enc211-01792018 irungu kirkstone njuguna enc211-03122018 korir jonathan kiprotich civil engineering jkuat Soil Mechanics Laboratory Experiment Compaction Test Objective To obtain moisture content at which dry density is a maximum when the soil is compacted in a standard manner.
Standard Proctor Test for Soils Abstract Soil Compaction is the process in which stress is applied to a soil which causes densification as the voids are filled with solids. In Geotechnical Engineering the soil is a particulate medium contain pore spaces which may or may. The test is conducted for five moisture contents to obtain the optimum water content for which the value of the dry unit weight is maximum.
Additionally you will find that the California and Uniform Building Codes the geotechnical engineer and structural engineers will also require soil compaction testing. According to compaction theory when samples of a soil are compacted at different water contents using. Preparation of Specimens- Prepare four mixes with WC ratios 04 05 055 06 and 065.
480221272 ABSTRACT This report examines the influence of moisture content on soil properties through a. For instance most regulatory agencies such as the Department of Transportation and American Society for Testing and Materials all require laboratory testing. The objective of this laboratory exercise was to determine the optimum moisture content and maximum dry density of a soil specimen using the standard proctor compaction test.
Standard vs Modified Proctor. The lab compaction report explains exactly what is too much soil also result in engineering. CIVIL ENGINEERING DEPARTMENT CE206 - INTRODUCTION TO SOIL MECHANICS LABORATORY II PROCTOR COMPACTION TEST Mulhem Şerafeddin 191503618 Submitted to.
Proctor Soil Compaction Test Procedure. 03 5441 4881 Email. Identify and report the optimum moisture content and the maximum dry density.
