Push the concrete sticking on its sides gently with the road.
. At the bottom of the upper hopper open the trapdoor so that concrete falls into the lower hopper and with the. LABORATORY II PROCTOR COMPACTION TEST Mulhem Şerafeddin 191503618 Submitted to. Sieve it through 20mm and 47mm sieve.
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. The compacting factor test is designed primarily for use in the laboratory but it can also be used in the field. Compaction Factor Test is classified into two sections viz.
Compacting Factor Test Lab Report. The slump test is perhaps the most widely used because of the simplicity of the apparatus required and the test procedure. Er Karen I20018814 Program.
The compaction factor test is designed for use in the laboratory but it is also used in the field. Concrete is designed for a particular strength. Procedure of Compaction Factor Test on Concrete.
There are the following steps in the procedure as given below. Proctor Soil Compaction Test Procedure. Compacting Factor Test is mainly used in laboratory to determine workability of concrete.
That is why quality control is one of the most important aspects taken into account during the production of. Lab Report Proctor Soil Compaction Test civil engineering department ce206 introduction to soil mechanics laboratory ii proctor compaction test mulhem. Weight balance is used to weight the concrete.
The total structural stability is dependent on a good quality concrete. Volkan KALPAKCI May 2020. Compaction energy is the amount of mechanical energy that is applied to the soil mass.
The moisture content of the soil is the factor used to determine the maximum dry density of the soil sample used while. It is used indirectly as a means of checking that the correct amount of water has been added to the mix. View compacting factor test reportdocx from CVE 2401 at INTI International University.
This test gives the seasonably a reliable assessment of the workability of concrete. The test procedure consists of the following series of steps. Procedure Of Compaction Factor Test.
Obtain about 3 kg of soil. First of all the concrete sample of the appropriate mix is prepared. Fill the upper hopper by pouring the concrete sample in it.
The Procedure of Compaction Factor Test. Weight the soil mass and the mold without the collar W m. Open the trapdoor at the bottom of the upper hopper so that concrete fall into the lower hopper.
It is more precise and sensitive than the slump test and is particularly useful for concrete mixes of very low workability and normally used when concrete is to be compacted by vibration. Ap1161b name muhammad alif iskandar muhammad salman muhammad aizat zameer haziqahtul najihah ainin sofiya nor maizatul wirdani nurin irdina nurul husni muhammad hafiz. It is not easy to measure the amount of work required to fully compact it.
For the normal range of concrete the compaction factor lies between 08 092. Take about 20kg of air-dried soil. Compaction factor test is a lab test and is generally conducted on concrete samples having very low workability.
The Compacting Factor Test is a laboratory test to determine the characteristic strength of the concrete but the making of test cubes is sometimes carried out by the supervisor on site. It is then thoroughly leveled. July 11 2021 by Saad Iqbal.
This cube test result is very important to the acceptance of concrete work since it demonstrates the strength of the design mix. Slump Test Lab Report. Steel rod of 16 cm diameter with a length of 61cm is used to tamp the concrete.
This test is particularly useful for dryer mixes for which the slump test is not satisfactory. By using the hand scoop place the concrete sample gently in the upper hopper to its brim and level it and then cover the cylinder. The slump test is a means of assessing the consistency of fresh concrete.
The compaction factor test is done to check the workability of concrete on the basis of weight ratio between partially compacted to fully compacted concrete. Fully Compacted Concrete 2. Discussion and conclusion.
The sensitivity of the compaction factor is reduced outside the normal range of workability and is generally unsatisfactory for compacting. If the percentage retained on 475mm sieve is greater than 20 use the large mould of 150mm diameter. The line of optimum moisture contents is usually around 85 saturation and the optimum moisture content decreases with increasing compactive effort.
Faculty of Engineering and Quantity Surveying FEQS CVE2401 Civil Engineering Materials Lab Report. We cant use the slump test for low workable concretes. Immediately open the gate at the bottom of the lower hopper to allow the concrete to fall into the cylindrical mould.
Concretes we mostly use in mass dam structures or road pavements have significantly low values of slump. The concrete sample is then placed on the upper hopper up to its brim using the hand scoop. The method applies to plain and air-entrained.
Faculty of architecture planning and surveying campus seri iskandar perak lab report compaction factor test course code. Compaction is greatly affected by soil type moisture content and compaction effort and is usually test using ASTM D698. Partially Compacted Concrete In Fully Compacted Concrete this is done with tamping the concrete while in the partially compacted.
Which Test Are You Using. Open the hinged door at the lower end of the upper hopper allowing the concrete to fall into the lower hopper. Standard Proctor 12400 ft -lbsft.
Calculate the percentage retained on 20mm sieve and 475mm sieve and the percentage passing 475mm sieve. Pass the soil through the No. Several methods can be used to compact soil in the field including tamping kneading vibration and.
As per IS11991999 Compaction factor test apparatus consists of Two conical hoppers and a bottom cylinder which is arranged as shown in below fig. The workability of concrete has also been defined as the amount of work required to place the concrete and to compact it thoroughly. The procedure of the Proctor Compaction Test consists of the following steps.
Place the soil in the mixer and gradually add water to reach the desired moisture content w. This laboratory test is performed to determine the relationship between the moisture content and the dry density of soil for a specified compaction energy. In this report it is concluded that the soil sample reaches its highest compact state when the dry unit weight is as its maximum value of 16kNm3 and 15 moisture content.
Place the concrete sample gently in the upper hopper to its brim using the hand scoop and level it. Compaction tests results vary with the input compactive effort usually measured in foot -pounds per cubic foot of soil. Scoop 1 fTHEORY This is a site test to determine the consistency or workability of concrete and is conducted in the lab.
