Slump Cone Test of Fresh Concrete. The tamping rod is of steel mm diameter and . Procedure to determine workability of fresh concrete by slump test. The internal surface of the mould is thoroughly . United Kingdom and mainland Europe.

Summary of Concrete Workability Test Methods.

This document first describes key principles and trends in the measurement of workability and then describes the test methods.

Based on the successes and failures of past test . This method of test specifies the procedure to be adopte either in the laboratory or during the progress of work in the fiel for determining, by the slump test , the consistency of concrete. Distribute rodding evenly over the entire cross section of the sample. Flow of concrete is reported as the percentage increase in average diameter of the spread over the base diameter of the cone (2mm in this case).

However, slump flow test is not yet incorporated in Indian standard . Each layer is rodded times to ensure compaction. The ease with which one can use concrete is called workability. It is one of the physical parameters of concrete which affects the finesse, strength and dura. All BSI British Standards available online in electronic and print formats.

Various international codes have specific testing standards for concrete slump test. These standards specify methods. The cone is known as slump cone or Abrams cone.

A number of companies undertake specialised slump testing. Tamping procedure Removing cone . Queensland Government Manual Tasks Code of Practice. The requirement pertains to observing the concrete displacement after the slump cone has been removed. Standard slumping cone is cleaned in preparation for slump testing . The mold is raised and the concrete allowed to subside.

The distance between the original and displaced position of the center of the top surface of the concrete is measured and reported as the slump of the concrete. Get contact details, address, map on Indiamart. This test method is intended to provide the . It is used for the determination of the consistency of freshly mixed concrete, where the maximum size of the aggregate does not exceed mm.

The apparatus consists of one slump cone with handles and foot pieces. Although it is very easy to perform this method. But it is not suitable for very wet or very dry concrete.

It does not measure all factors contributing to. Gently remove the cone from the concrete. The result of this slump test value should be recorded in millimeters.
