Beyond these extremes the measurement of slump can be unsuitable and other methods of determining the ...
Jan 29, 2021· 2.4. Test Procedure 2.4.1. Slump Test. Slump test was widely utilized to estimate the fluidity and working performance of concrete, and the operation was in accordance with specification (GB/T50081-2002, 2002; ASTM C143–C143M-15a, 2015). 2.4.2. Compressive Strength Test
Mar 21, 2021· Procedure for Slump Test of Concrete:-. Preparation of Specimens:- Mixtures are prepared with W/C ratio 0.4, 0.5, 0.55 and 0.6. For each mixtures, take Cement = 2.5 kg, C.A. = 10 kg and F.A. = 5 kg. Mix the dry constituents thoroughly to get a uniform colour then add water in the mixture. The internal surface of the mould is to be completely ...
The surface under test should be clean and smooth. Dirt or other loose material on the surface can be removed using a grinding stone prior to the test. Rough surfaces cannot be tested as they do not give reliable results. ... A procedure for doing this is given in BS EN 12504-2. The values obtained by using the hammer may be influenced by the ...
Mar 09, 2017· The slump test is perhaps the most widely used because of the simplicity of the apparatus required and the test procedure. The slump test indicates the behavior of a compacted concrete cone under the action of gravitational forces. The slump test is a practical means of measuring the workability. Changes in the value of slump obtained during a ...
Consistence tolerance - slump test. Consistence, measured using the slump test (BS EN 12350-2), is either specified as a class or target.Although a supplier will endeavour to provide the required value or range, deviations in production and sampling apply.
the slump cone. Measure the amount of slump in inches from the bottom of the straight edge to the top of the slumped concrete at a point over the original center of the base. The slump operation shall be completed in a maximum elapsed time of 2 1/2 minutes. Discard concrete. DO NOT use in any other tests. SLUMP TEST PROCEDURE (FIELD TESTING) 1
Each procedure or test method must be conducted properly and within the required time frame to be comparable. Fresh concrete tests run along with a set of compressive strength cylinders are: slump, air content, unit weight and temperature.
Slump Class Slump in mm S1 10 -40 S2 50 -90 S3 100 -150 S4 160 -210 S5 ≥220 Site Testing -Slump Test Always do your slump test before making your cubes to ensure the concrete is usable. If the slump test fails to meet the range limit as dictated by the ritish Standard (shown in the table below) then the load should be rejected. Place the damp ...
Workability is largely determined by how fluid the concrete is. This is referred to as "Slump". Essentially, the more fluid the concrete, the higher the slump. Although slump is often seen as an indication of water content, it is more legitimately interpreted as a measure of consistence. Following the adoption of the new European Standard for ...
