Article Preview

The cement mortar with glass fiber (GF) can be widely used in strengthen different structure elements. In general, discrete glass fiber was used for improving the tensile strength of mortar. In article, the optimum material contents (sand, cement, water and fiber) enhancement compression strength with tensile strength was investigated. Forty-two specimens are tested after 28 days. Each specimen has of 3 cubes 15*15*15 and the average results were taken into consideration. The mortar content is cement, sand, water and discrete glass fiber. The fiber lengths (L f) are 20, 35, 50 mm. the fiber contents ( Vf ) are 1.5%, 3.0% and 4.5%. The water cement ratios (W/C) are 0.47, 0.42, and 0.37. The cement sand ratios (C/S) are 1:2, 1:3 and 1:4. The results show that, b y reducing the C/S ratio, the discrete glass fiber used is not recommended using. Moreover, from the experimental studies, the curves required for awareness the mixed material of mortar with discrete glass fiber were plotted. The theoretical equation that can be used in the initial trial mixing design is determined. This type of mortar can be successfully used for repairing or strengthen brick wall, or replaced instant of steel mish for resistance change temperature between wall layers.
