Investigation of Wastes Plastic and Glass to Enhance Physical - Mechanical Properties of Fired Clay Brick

Abstract

Around the world, large amounts of plastic and glass waste have been collected. This work is given as a way to reduce this material. This paper aims to investigate how fired clay bricks' physical and mechanical properties are affected by plastic/glass (P/G) powder. It is used as a replacement for clay, varying the plastic/glass content 00/20, 05/15, 10/10, 15/05, and 20/00 weight %. The ratio of soil to water remains constant 0.3. The maximum temperature is presented after three fire phases. The temperatures are 300 °C for the first, 600 °C for the second, and 900 °C for the third. Results for the physical properties showed an increase in the water absorption of clay brick specimens as the plastic content increased; in addition, efflorescence was increased with plastic powder. However, the density and firing shrinkage decrease with plastic quantity. Also, the experimental results showed a decrease in water absorption and efflorescence when the glass powder was increased. While the density is higher when glass powder is 20 %. According to the findings on mechanical properties, clay brick samples with higher plastic powder content 20 % displayed a decrease in compressive strength and flexural bending strength, i. e. the mechanical properties (compressive and flexural strengths) are increased with the increased

Investigation of Using Waste Glass Powder (WGP) as a Partial Natural Sand Replacement in Concrete for a Potential Use in Iraqi Construction Field

“…Originally, three main ingredients that form shapeless glass, are lime or calcium oxide, Sodium carbonate, and high content of silica. These unique glass compositions make end-use glass an appropriate raw supplementary material [7][8] [9] Fig. 3: Global waste composition percentage [6].…”
