Abstracts: Fiber cement composite materials are basically mortar and concrete compositesmade with addition of different types of fibers which represent a special micro-reinforcement.Uniformly dispersed fibers are strengthening the cement matrix, thus improving thewhole set of properties of the basic material. The cement matrix, as the base, can be reinforcedusing metalic (steel), synthetic (polymeric), ceramic (glass), or natural (organic) fibers. Essentialy, the fiber concept is about the increment of quality of a complex composite material (mortar and concrete) by improving certain properties of fresh and hardened material which are crucial for its practical application. The best effects are achieved in the field of strength improvement (especially in flexure, tension and shear) as well as in ductility increment of the above mentioned composites. Also, good results are obtained concerning the reduction of shrinkage, as well as the improvement of fatigue and impact resistance behavior. In this research is to various fiber materials as addition in cement mortar accordingly in the range of 0%, 0.10%, 0.20% and 0.30% by weight of 1:6 proportion of mortar.To check mechanical properties of cement mortar by Compression Test (at 7, 14 and 28 days), Water absorption test (at 28 days).
