BS EN 12350-Part-2: Slump Test

Testing Fresh Concrete

This European standard specifies a method for determining the consistency of fresh concrete.

1- Apparatus Required

1- Base Plate 3- Compacting Rod2- Slump Cone

This test in not suitable when the maximum size of aggregate in concrete is greater than 40 mm.

Before taking a sample of freshly mixed concrete, dampen

the sampling container (wheelbarrow) toughly by clean

water. Take a sample of freshly mixed concrete by using

every precaution that assist in obtaining sample that are trulyrepresentative of the nature and condition of concrete. Take

enough sample to perform the Slump test and if there is any

test specimen required to take for testing.

1. Sampling

Test specimen made of metal not readily attacked

by cement paste, smooth free from dent, not thinner

than 1.5 mm, with diameter of base (2002)mm,

diameter of top (1002)mm, height of (3002)mm,

having open base and top parallel to each other at

right angles.

4- Scoop 5- Wheelbarrow

Capable of accurately measuring the

temperature through [0 to 50C] . With

immersion of 3 in. [75 mm]

2- Procedure

This test is sensitive to changes in the consistency of concrete which correspond to slumps between 10mm and 200mm.Beyond these extremes the measurement of slump

can be unsuitable.

Graduated form 0 mm to 300 mm, at

intervals not exceeding 5 mm.The zero

mark begin at the extreme end of the

ruler.

Made of hard non-absorbent material to

ensure proper mixing of concrete.

Made of a non-absorbent solid material , Rigid, flat

plate.

Made of steel or other non-absorbent hard material.

Straight having diameter of (16 1) mm and length

of (600 5) mm with rounded ends.

6- Thermometer 7- Measuring Ruler

A container made from non-absorbent

material not attacked by cement paste,

with appropriate dimensions such that

the concrete can be toughly re-mixed.
