EFFECT OF TEMPERATURE ON THE CRUSHING STRENGTH …

It is shown that crushing strength of concrete up to 600c is independent of the water/cement ratio used but is influenced by the cement/aggregate ratio. Concrete specimens loaded to produce normal design compressive stress during the period of heating showed less reduction in strength than specimens without imposed load.
