64 JOURNAL OF MATERIALS AND ENGINEERING STRUCTURES 7 (2020) 57–72 to keep the same proportion as illustrated in Table 4. The mix proportion for all mortar specimens was 1:2 and water/ cement ratio equal to 0.4, where the amount of cement, fine aggregate and water was altered for all blends to keep the identical proportion as shown in Table 5. The two procedures were performed utilizing electrical tilting drum of 0.16m3 capacity in the laboratory. Pre to casting, each inner surface of the molds was carefully oiled using lubricant oil. Mixing and casting were done in the laboratory at the surrounding temperature of 25±1oC. Firstly, a small amount of cement was mixed with the gravel and sand or PE granules for about three minutes until they coated by fines. The remaining cement and water were added to the mixture and the materials were let to mixtures for another 3 min ( see Fig. 5) Specimen molds were filled with concrete in 3 layers, every layer undergoes to an exterior vibration. The cast concrete or mortar top surface of well leveled using a trowel. The specimens were demolded after 24 hours from casting. Curing of all specimens was done in the lab at 25±1 Co temperature . All samples were water handled in a container for 28 days, later left in the laboratory for little days to dry before testing.
