THE BASICS OF A SYSTEM FOR EVALUATION OF FIBER-CEMENT MATERIALS BASED ON ACOUSTIC EMISSION AND TIME-FREQUENCY ANALYSIS

The basics of a system for evaluation of fiber-cement materials based on acoustic emission and time-frequency analysis

Fiber-cement building products are increasingly used in construction.They are used as building Springform Pans and finishing material for facades, internal walls and roofs.Numerous advantages such as relatively low weight, low absorbability and relatively high strength allow to use these materials in bulky constructions and in buildings which are c
