On the mechanical properties of Polymer Portland Cement Concrete

In this paper. epoxy which is the most common type of polymer used by civil engineers. and polyester. which is cheaper than most other types of polymers. were utilized to produce Polymer Portland Cement Concrete (PPCC). A rich concrete mix was designed and then five different ratios of cement (0, 20, 40, 60 and 100%) were replaced by either epoxy or polyester, rendering five different mixes for each type of polymer. Three types of samples were cast, compacted and then cured for 28 days. The three types of samples are standard beams of size 150x150x600 mm. standard cubes and standard cylinders. One third of the specimens were tested a( room temperature, while the rest of the specimens were heated in an oven for 24 hours. Specimens were heated to two temperature stations of 80degreesC and 150degreesC. Samples received for flexure, compression, split tension. and direct shear tests, using a specially manufactured apparatus that was used before and found to be effective. The variations of compressive strength. split tensile strength. direct shear Strength. and flexural strength with different variables such as temperature. percentage of polymer and type of polymer were determined and assessed.
