Abstract

Plastic wastes could threaten the ecosystem of the environment because it is non-biodegradable material. The efforts to reduce the plastic trash are taken by 3R-way (Reuse, Reduce, Recycles). How to recycle for example by the use of plastic trash: to make oils, as a composites for construction, for example: as the fiber in the concrete, and as a fiber for soil reinforcement. We will try to reinforcement of clay by using plastic trash to increase of the shear strength of clay. Plastic trash is cut into small pieces with 1x1 (cm) and 1x0,5 (cm) size mixed with clay, compacted, and then tested in the laboratory by Unconfined Compressive Test. Plastic trash using of the former mineral water containers (PET plastic types). The results of this research showed that the addition of small pieces of the plastic trash in clay: (1) will increase the value of qu (unconfined compressive strength) of soil at the rate of 3% of plastic on Kasongan clay, and only if the plastic is large cutting (1x1) cm on Wates clay. (2) will increase the internal friction-angle ? if the plastic content of 3% (Kasongan clay) and Wates clay but only if the plastic is large cutting (1x1) cm. (c) will increase of the soil friction if at the rate of 2% of plastic (Kasongan clay), will increase of the soil friction if the small size (0,5 x 1) cm of plastic pieces (Wates clay).
