The diagram represents a sequence of tests performed on S C B (sustainable concrete block) samples to assess their fire performance and mechanical properties. At the top, there are three separate testing conditions: On the left, a description reads “100 millimeters times 100 millimeters S C B samples subjected to 35 kilowatt meters to the negative 2 power and 50 kilowatt meters to the negative 2 power,” connected by a vertical line to a dashed rounded rectangle labeled “Cone calorimeter test.” In the center, the text states “S C B exposed to 1 hour heating at 200 degrees Celsius, 400 degrees Celsius, and 600 degrees Celsius,” linked downward to another dashed box labeled “Elevated temperature material test.” On the right, a brick wall icon with a red flame and tilted grey block represents fire exposure; this is labeled “S C B wall exposed to 2-hour furnace” and is connected to a box titled “Fire resistance furnace test.” All three testing boxes are visually aligned within a light blue rectangular band. Two arrows from the elevated temperature material test and the fire resistance furnace test converge on a lower dashed box labeled “Compressive strength test.” From this box, two arrows branch out: the left arrow points to the phrase “Ultimate load,” while the right arrow leads to “Load versus deformation curve,” indicating the outcomes measured from the test.Series of experimental tests and heating conditions, and durations.
