Evaluation of loading methods for determination of material and elastic constants of cement fiber board

Abstract

Cement fiber boards (CFB) are special group that are used in a wide range of structural civil engineering. For the correct design of a cement fibre board structure, it is important to define their material and elastic constants, which are usually determined by destructive tests. The paper deals with a definition of a suitable method of loading for the determination of basic materials and elastic constants of cement fiber boards reinforced with organic fibers loaded in the mid- plane. The publication compares and evaluates load tests by three-point and four-point bend.Cement fiber boards (CFB) are special group that are used in a wide range of structural civil engineering.
