POLYMER CONCRETE COMPOSITION AND CONSTRUCTION METHOD FOR ROAD PAVEMENT THEREOF
The polymer concrete composition of the present invention comprises: 37 to 48 wt% of fine aggregate; 30 to 40 wt% of coarse aggregate; 10 to 20 wt% of rapid curing cement; 0.6 to 2 wt% of activated silica; 3.2 to 4.2 wt% of polymer; and 3 to 4.5 wt% of water. The activated silica comprises: 0.7 to 0.8 parts by weight of silicon dioxide (SiO_2); 0.08 to 0.15 parts by weight of aluminum oxide (Al_2O_3); 0.03 to 0.05 parts by weight of iron oxide (Fe_2O_3); 0.01 to 0.05 parts by weight of calcium oxide (CaO); 0.01 to 0.05 parts by weight of magnesium oxide (MgO); 0.005 to 0.015 parts by weight of sodium oxide (Na_2O) and K_2O; and 0.0002 to 00005 parts by weight of sodium chloride (NaCl), based on the weight of the activated silica. The polymer is a mixture of ethyl prop-2-enoate and 2-methyl prop-2-enoic acid. It is preferable that the polymer is mixed with 0.4 to 0.9 parts by weight of ethyl prop-2-enoate and 0.1 to 0.6 parts by weight of 2-methyl prop-2-enoic acid, based on the weight of the polymer. The polymer concrete composition according to the present invention has excellent flexural strength, adhesion strength, and compressive strength.
