References not included in my previous post: Color change of concrete: ACI Journal, November, 1963, page 1539: "Below 450 F color is normal. Progressively from 550 F to 1100 F, pink hue deepens to red. Between 1100 F and 1650 F color changes back through grey to buff." Also at same location in reference, "Quartz pop-out at 1070 R; Spalling over steel to expose not more than one-quarter of bar: 1450 F; White powder of decomposed cement hydration products: 1650 F; Surface crazing: approximately 530 F; Deeper cracking: approximately 1000 F." "In the absence of tests, pink concrete and beyond should be suspect concrete; 1450 F steel and beyond as suspect steel. The general temperature of a wood fire is likely to be about 1000 F and that of glowing coals about 2000 F." Also other references: ACI SP-92, Evaluation and Repair of Fire Damage to Concrete. ACI SP-80, Fire Safety of Concrete Structures. Hope this helps. A.
