| Abstract This study investigated the use of waste papers as fiber reinforced mortar. The fibers have been collected from office paper shredders. Investigation was carried out on cement mortar samples. Different percentages of fibers i. e., 0. 5%, 1. 0%, 1. 5%, 2. 0%, 2. 5% and 3% by weight with the addition of super plasticizer by 2% of the weight of cement and compare the results with control mix. Mechanical properties such as compressive strength, flexure, density and water absorption were measured. The results indicated that the addition of waste paper decreases the compressive and flexural strength, increases water absorption and reduces the density so it could be considered as structurally lightweight concrete mortars. The results revealed that the addition of waste paper fibers reduces defragment of mortar and the samples with fibers keep their original shape after failure and the crack are very thin compared to control mix. Moreover they could sustain loads up to 93% of the failure load if they are subjected to preloading condition. | ||
