I planning some research experiments using GGBS as Supplementary Cementitious Material in Concrete.
Due to Covid_19 pandemic situation  I have got a stock of 2 years old GGBS.
Can I use this old stock. Is its age going to  affect any properties of concrete??

Please elaborate storage conditions
Was its storage air tight?
Was it storage moisture free or no ingress of moisture being permitted?
Was is stored in a way OPC is stored or some other way?

Sir,
It is just stored in a godown kind of room along with some construction equipment in the concrete laboratory in our institution.  The room doesn't have any exterior wall of the building.

This means store does not meet professional protective requirements
GGBS cannot survive in that case

Though not an expert on CT , just a layman's view :

If quantity of GGBS is huge ,  it is better to get it tested for its usage . Samples to be taken from different locations of storage to have representative samples.

Just a thought that crept in my mind , may be ignored if seems laughable

Dear Sir,
    Why not consider your first research into effect of ageing of stock by conducting a comparative study of the old stock GGBS with new stock GGBS for strength, workability, etc? This will at least use up some of your stock as well as act as a research material.

Yours sincerely
S Arunkumar
