تدوير مخلفات مصانع البلاستيك 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 mixture (A ) is 13 MPa and for 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 for 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...
