Hi,

We are setting up a calibrations program, and we require stone blocks of specific densities. I have provided you with the requirements of the limestone blocks that I need to source as soon as they can possibly be available:
We require 2x limestone blocks that shall have minimum dimensions of 560 mm length × 460 mm width and a depth of 360 mm.

(The top surface of each block shall be finished with an out-of-flatness not exceeding 0.5 mm. When determining the density of a block in accordance with AS 1289.5.8.5, using direct measurement of volume, each of the other surfaces of the block shall be finished with an out-of-flatness not exceeding 1 mm.
A direct transmission access hole of diameter not exceeding 20 mm shall be drilled in the block, normal to the top surface.)

The density range that we are aiming for is ~ 1.7 (t/m3).
Do you potentially have limestone blocks to cut to this size at the quarry? Are you able to check the density of your limestone to get a block that fits our 1.7 t/m3 density range????
Looking forward to hearing from you soon.
