Plastics -- Recycling
Polyethylene Terephthalate (PET)
Polymer Portland Cement Concrete (PPCC)
How to handle the plastic waste is a big task for the modern society in environmental protection. People already focus on it, especially in PET soft drink bottles. Although PET bottle can be reclaimed, its usages are restricted due to the limitation in color and difficulty in purification.
On the other side, concrete is the most common material for human beings to used [sic] in construction. Concrete has good compressive strength, but poor [sic] in flexural and tensile strengths, which limits its applications. So, scientists try to improve its properties by adding the polymer into the conventional concrete, to enhance its strengths, chemical resistance and ductility.
In this study, the behaviors of the PPCC in corporation [sic] of the recycled plastics as filler, without causing any problem of color and purity, has been investigated on tensile, flexural and compressive strengths, weight reduction and weathering test. The reason to chose [sic] the unsaturated polyester polymer Portland cement concrete (UP-PPCC) is to develop a novel method to transfer the plastics waste to valuable product and to solve the problem about dumping the million tons of plastic waste.
The results of experiments show that UP-PPCC system has very good adhesive ability to bind the flakes of plastics with polymer-concrete matrix and the light-weighing [sic] plastic concrete can cut down the cost of transportation.
