compression test on sand 1

[queiry]

A chemical has been developed for dust abatement, made up of polysaccharide, surfactant, mordant and water.

I have to perform a compression test on the sample (solution mixed with sand and cured). The resulting crust is similar to concrete, but not as strong. I have to test various concentrations of the solution and correlate compressive strength of the crust with concentration.

MY QUESTION: Does anyone have guidelines for the sample preparation (size, shape...) and testing?

We are using an Instron 5500R, which uses 2 disks for compression.

ASTM International has several standards for compression testing of various materials. For example:

C39/C39M-04a Standard Test Method for Compressive Strength of Cylindrical Concrete Specimens

Thanks for the reply, Cory.

I should have mentioned in my message that I have a couple of ASTM standards: for cohesive soil and for concrete.

The resulting crust lies somewhere in between. I was hoping someone would have experience with something comparable, and would have some insights to share.

Thanks again,
Marc

Perform a search at the ASTM Internet site - there are hundreds of standards in this general area, and you should be able to find a suitable one.
