The determination of the cold crushing strength (CCS) of porous materials is also significant, and thus, a CCS tester (make: Aimil, India) was used to determine the CCS of the specimens, as shown in Figure 10a,b. The preform was rigidly attached to the CCS tester and subjected to a gradually increasing compressive load until it failed.
