Compressive Strength and Fire Resistance Relationship

11/14/2015 5:10 PM

I am wondering if there are a set of calculations used to show the relationship of compressive strength of concrete and a rise of temperature? Or if there is a relationship involving the heat resistance and characteristic strength? I would also like to know how I would go about creating a concrete and finding strength? I'm trying to find out how to battle the deterioration of the strength of concrete under fire conditions. Any help would be appreciated. Thanks

Not everything can be solved with calculations.

There are many tables that already exist that explain concrete formulas.

Have you done ANY research before coming here? I think that should be your first assignment.

NRMCA | National Ready Mixed Concrete Association ...

American Society of Concrete Contractors | ASCC

American Concrete Institute

State and national concrete associations provided by the ...

PCA - The Portland Cement Association - America's Cement ...

Until you do some work on your own, you're just wasting our time.

Now, get busy!

The only way is to avoid a too high temperature since the stuff suffers from heat.

Thermal bariers of different kinds.

Concrete holds moisture, as the moisture heats up it expands and the concrete explodes...

This may provide you reference

1) Analysis of temperature gradients

2) Cracking of Concrete
