This page shows our apparatus for concrete mixing and casting for tests.

 

DSCF0114

 

This is our largest mixer with a maximum capacity of 30 50 litres depending on the mix.

Second year students design a concrete mix and make it in this mixer.

These pictures shows some of our mini-beam moulds and our rack of cube and cylinder moulds.

In total we have:

12 gangs of 3 no. 50mm cube moulds

51 no. 100mm cube moulds

17 no. 150mm cube moulds

12 no. 500mm by 100mm by 100mm mini-beam moulds

15 no. 100mm diameter cylinder moulds.

Plus a large number of plastic moulds (in the left hand picture) which we now generally use in place of the metal ones.

This balance has a capacity of 250 kg. In the casting area we also have a large 25kg mechanical balance and a 30kg electronic one.

 

DSCF0117

 

This is our vibrating table on which we compact most of our samples.

 

 

DSCF0111

 

We have two electric poker-vibrators.

 

 

DSCF0012

 

The curing room has several tanks which we can control to temperature.

 

DSCF0013

 

We have a number of laboratory ovens for drying samples.
