TEST FOR WORKABILITY OF CONCRETE - SLUMP CONE

[@exiledguardian5862]

For everyones benefit, acceptable safe slump for reinforced foundation walls/footings/pavement 25-80mm, beams/columns 25-80mm, slab 50-100mm, piling 100-150mm. Beyond these values are not safe.

As per IS 1199 slump cone is filled in four layer,so don't confuse with comments. This video is wonderful and precise

Slump test express the consistency of concrete mix, workability is measured by " Compacting factor" or " Remoulding test by Jolting" or " V.B test".

AWESOME, now I can go take my GC exam!!! :)

[@mohamedelgendy62]

no rotation allowed when lifting the cone see ASTM C143

[@sangwanyi4469]

Carefully in a vertical direction. By a steady upward lift with no lateral or torsional motion.

[@danbiss87]

Why is it undesirable for a shear or collapsable slump test? Its great to know what is preferred but equally important to understand why

[@danbiss87]

I get that but what are the dangers when contractors the slump test fails and contractors use it anyways. I say this because many contractors provide shotty work. In what ways does it effect the integrity of the concrete? Are their any telling signs?

[@michaelpatungan1020]

Aside from affecting ease of work (pouring using pumpcrete tend to be difficult if slump is too low), it may result to severe honeycombing on structural members, reducing integrity of the structure.

[@Shivakumar-dq9xl]

why the slump cone is conical ?

[@UltraTechCementLimited]

Hi Siva, Slump is a test to understand the Workability of Concrete. A cylinder may not just slump, it might also fall apart due to a lack of cohesion. The angle ( called the angle of repose) is the steepest at which the sand grains don't slide down the hill. This limiting point is the same all the way down the pile and that's the angle of the cone & that's the reason slump cones are conical. Regards, Team UltraTech

[@pakwunlee]

The slump cone shall be removed by raising it vertically, slowly and carefully, in two to five seconds, in such a manner as to impart minimum lateral or torsional movement to the concrete. (extracted from Construction Standard of HKSAR) You guys did twist the cone

You need to dampen the cone and the base plate before putting any concrete in. You don’t clean the concrete off the top with a trowel. You use the tamping rod in a screeting motion. You don’t twist the cone as you pull up. It must be straight. Also you don’t measure to the highest point of the concrete. You measure to the displaced center of the concrete. Read the ASTM standard please.

[@nirmalendukargupta201]

Okay boss. If all would have done as you said, what would be the difference of slump in two different method? It is wise to be a practical rather to to find fault with anything...

[@HA-jh3cg]

I agree with you with the dampening, the use of the tamping rod to level off the concrete and the not twisting. In the UK though the standard specifies that you measure to the highest point. Now I want to read the ASTM standard and compare :)

[@HA-jh3cg]

@@nirmalendukargupta201 Doing it with a dry cone and baseplate and twisting it while lifting will give a lower slump value. Unscrupulous site technicians have been known to deliberately do it this way to "cheat" the test and make an otherwise too liquid concrete pass
