compaction test lab report

Take about 20kg of air-dried soil. The Process and Soil Compaction Tests.

If the percentage retained on 475mm sieve is greater than 20 use the large mould of 150mm diameter.

. 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. Compaction factor test was developed by Road Research Laboratory in United Kingdom. 11761167 Date15-03-2015 OBJECTIVE To find the CBR value of the soil in controlled moisture content and in molded conditions.

Place soil in the mold in 3 layers. Proctor compaction test measures the maximum unit load that a particular type of soil can be compacted to use a controlled compact force at an optimal water content. GSai Venkateswarlu Yang Xiaoming PhDPE.

The sample was then massed out the next day. Meld was prepared on a hard flat surface. Compaction of soils is a very essential procedure in geotechnical engineering it helps in improving the strength of the structures such as height way construction and airports.

An extremely important task of geotechnical engineers. Therefore the standard proctor. The lab compaction report explains exactly what is too much soil also result in engineering.

Sieve it through 20mm and 47mm sieve. Compaction is a process in which the soil particles are mechanically compacted to increase densities. Compaction Control Test Report Report Number.

Lab Report 3. Assemble the compaction tool. A small sample of the material is prepared weighed and placed into the vessel.

Hammer shown in figure 4. The hammer has a 25kg ram which can be lifted 300mm and dropped. The total volume of the mold is 1000cm3.

Compact the soil with 25 well-distributed blows of the hammer. Such concrete may be consistently fail to slump. The standard proctor compaction test was first developed by RR.

Proctor 1933 for assessing compacted fill and from then it became a universal standard test. Proctor Soil Compaction Test Procedure. After each compaction a sample of the soil was taken and placed into a separate moisture can.

The maximum dry density and optimum moisture. Content is determined from the results of the test. Geotechnical Lab Report on Soil Compaction.

This plays a vital part in construction for soils are mainly used as supports for a lot of infrastructures. To find the moisture content a sample of soil from each step was gathered massed out and placed in an oven to dry overnight. That concept is known today as the moisture-density relationship test laboratory compaction characteristics of soils or simply the standard Proctor test and is detailed in ASTM D698 and AASHTO T 99 test methods.

Density compaction curves based on 18000 compaction tests compiled by the Ohio DOT The Speedy Moisture Meter is a portable system comprising a vessel with an integral pressure gauge a weighing scale in a portable case. The test consists of compacting the soil or aggregate to be tested into a. Proctor 1933 for assessing compacted fill and from then it became a universal standard test.

Levels of moisture content. In the proctor compaction test a soil sample is compacted into a standard mold shown in figure 4. 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.

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. Calculate the percentage retained on 20mm sieve and 475mm sieve and the percentage passing 475mm sieve. Unit weights and moisture content field tests could now be expressed as a percent of the laboratory values for the same soil making it easier for the.

Compaction reduces the voids ratio making it more difficult for water to flow through soil. Therefore the standard proctor. Obtain layered soil sample via our VTK Soil Sampler if equipped Determine the weight of the Proctor mold with the base and the collar extension.

The moisture content of the soil is the factor used to determine. Under the guidance of. It was then placed into an oven in order to find the moisture content of the soil.

It is the most common laboratory soil test and is the basis for all engineered compact soil placements for embankments pavements and structural mills. Standard mould using a standardized compactive energy at several different. Compaction is greatly affected by soil type moisture content and compaction.

Compaction of soils is a very essential procedure in geotechnical engineering it helps in improving the strength of the structures such as height way construction and airports. Compaction of the soil is carried out using the standard. From the water content the dry density of compaction can also be found by using the following formula.

The standard proctor compaction test was first developed by RR. Mechanical compaction is one of the most common and cost effective means of stabilizing soils. In order to compact the soil a compaction mould with volume 1178 cm3 and empty mass 4618 g and standard Proctor Hammer were used.
