How to calculate volume of mould required for slump test
The concrete slump test calculates the consistency of brand new concrete prior to it sets in that particular batch. It is carried out to verify the consistency of concrete that is formed newly. Consistency means the easiness with which concrete pours. It is applied to specify degree of wetness. Consistency impacts the adaptability of concrete.
In this construction video tutorial, one can learn how to work out the volume of slump test mould with some easy to follow processes. On the upper part of the mould, a surface is created for circle and it’s diameter is taken as 100 mm and diameter of the bottom is taken as 200 mm.
Radium of the top surface of the mould is represented as r and bottom surface as R. The height is represented as h.
To find out the volume, the following formula is used
Πh/3 (R2+Rr+r2) = 3.14 x 0.3/3 (0.12 + 0.1 x 0.05 + 0.052) = 0.0055 Cubic meter
As diameter of top surface is 100 mm, so, radius is 50 mm i.e. 0.05 m
As diameter of bottom surface is 200 mm, so, radius is 100 mm i.e. 0.1 m
Height is taken as 300 mm = 0.3 m
