This page shows our apparatus for concrete mixing and casting for tests.
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 are our 2 smaller concrete mixers with capacities of approximately 15 litres and 5 litres.
We also have a number of high-shear mixes for mortar and paste (grouts).
We have a ball mill for grinding cement and cement clinker and cement replacement materials.
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.
This is our vibrating table on which we compact most of our samples.
We have two electric poker-vibrators.
The curing room has several tanks which we can control to temperature.
We have a number of laboratory ovens for drying samples.
This saw is used for cutting the ends from cores etc.
