<p>PURPOSE: A polymer concrete composition recycling waste extended polystyrene as a shrinkage reducing agent, polymer concrete using the same, and a method for manufacturing the same are provided to recycle the waste extended polystyrene as a binder for a liquid resin-shaped composite. CONSTITUTION: A polymer concrete composition comprises a unsaturated polyester resin, 1-20 parts by weight of waste extended polystyrene, 10-50 parts by weight of a vinyl monomer, 150-1,200 parts by weight of quenching steel slag, 100-600 parts by weight of filler, and 100-1,200 parts by weight of thick aggregates based on 100 parts by weight of the unsaturated polyester resin. The unsaturated polyester resin is ortho unsaturated polyester having an average molecular weight of 1,000-10,000.</p> |
