Step 2

· Thoroughly remix the sample shovelling into a heap

· Turn the heap over to form another

· Do this three times

· Flatten the final heap by repeatedly digging in the shovel vertically

· Lift the shovel clear each time

Step 3

· Fill the Mould with concrete in 50mm layers

· Using the special Compacting Bar, compact the concrete with no less than   

    25 tamps for each of the two layers in a 100mm Mould

    35 tamps for each of the three layers in a 150mm Mould

For very high workability concrete you may not need the minimum number of tamps

Step 4

· Remove surplus concrete and smooth over with a float

· Wipe clean the Mould edges

· Number the Moulds for identification

Step 5

· Cover each Mould with a damp cloth and plastic sheet

· Store inside at normal room temperature (15 – 25^oC)

· Protect the Cube Moulds at all times from high and low

  temperatures (especially frost) and drying winds

· Complete the sampling and cube making certificates
