Slag cement
Slag cement
(OP)
I have finally been able to find someone willing to sell me a ton of slag cement. Unfortunately I would be paying close to double the bulk rate and I also have to pay labor involved in shoveling out 1 ton from the truck. I wanted slag cement for precast concrete. The mix design I would use has tested at 10,000 psi and I think if I could have tested cylinders that rated 10,000 psi it would be great for marketing purposes.
The problem I am struggling with is the price as I am a very small business who has a long way to go before becoming profitable and this is way more expensive than just Portland cement. I am curious what others think about how important slag cement is for having a high strength concrete product.

RE: Slag cement
Next.....I would be suspicious of any cement delivery that does not come in a sealed tanker. Even high humidity can start to affect open stored cement.
RE: Slag cement
Great point about sealed containers. If not controlled, storage can kill any cemetitious material (even with waterproof bags) and time is a problem with a low volume material.
Some cement companies do not make slag cement on a regular enough basis because of the low volume and uncontrolled storage. A ton of cement does not go very far, so it must expected because of the low volumes used in a volume oriented lower profit industry.
