تدوير مخلفات مصانع االبلاستيك في عمل ألواح تغليف الجدران والسقوف عازلة للرطوبة والحرارة

Abstract

The work includes making concrete boards or panels used to cover walls from inside and false ceiling with dimension 200 * 200 * 30 mm , using Iraqi plastic factories wastes , by mixing it with cement , sand and water , using Polyvinyl Chloride and Acetate ( PVC ) to give panels high resistance for erosion , moisture and friction . Two mixes were used , first mixture (A)is 1 cement : 1 sand : 2 plastic wastes by size , the second mixture (B)is 1 cement : 2 sand : 3 plastic wastes by size . For the added material Polyvinyl Chloride and Acetate , many ratio were tried , the best ratio of this material to the weight of cement is 0.3 %. These boards were characterized by their high compressive strength; for the mixture (A ) is 13 MPa and for the mixture ( B ) is 8 MPa. The flexural strength for mix ( A )is 2.92 MPa while for mix ( B ) is 2.08 MPa, in addition to their good resistance to moisture, the percentage of absorption for mix ( A )is 2 % and for mix ( B ) is 3 %. Thermal insulation for mix ( A ) is 0.322 w/m2 c and for mix (B )is 0.375 w/m² c , this is very good as compared with other materials used for coating. The other expected function of the production of these boards is the exploitation of various plastic factories' wastes.
