TI  - Experimental Study on Cementless PET Mortar with Marble Powder and Iron Slag as 
      an Aggregate.

AB  - There has been an increase in plastic production during the past decades, yet the 
      recycling of plastic remains relatively low. Incorporating plastic in concrete 
      can mitigate environmental pollution. The use of waste polyethylene terephthalate 
      (PET) bottles as an aggregate weakens properties of concrete. An alternative is 
      to use PET bottles as a binder in the mortar. The PET binder mixed with sand 
      results in weak mortar. Marble and iron slag can enhance PET mortar properties by 
      preventing alkali reactions. This study examines the mechanical and durability 
      properties of PET mortar with different mixes. The mixes were prepared as plastic 
      and marble (PM); plastic and iron slag (PI); plastic, sand, and marble (PSM); 
      plastic, iron slag, and marble (PIM); and plastic, sand, and iron slag (PSI). PM 
      with 30-45% plastic content had increased compressive and flexural strength up to 
      35.73% and 20.21%, respectively. PI with 30-35% plastic content showed strength 
      improvements up to 29.19% and 5.02%, respectively. However, at 45% plastic 
      content, strength decreased by 8.8% and 27.90%. PSM, PIM, and PSI specimens had 
      nearly double the strength of ordinary Portland cement (OPC) mortar. The 
      durability of PET mortar in chemical solutions, mainly 5% HCl and 20% NaOH, 
      indicate that mass decreased after 3, 7, and 28 days. All specimens showed good 
      resistance to HCl and NaCl solutions compared to OPC mortar. However, its 
      resistance to NaOH is low compared to OPC mortar. PET mortar without cement 
      showed higher strength and durability than cement mortar, making it suitable for 
      paver tiles, drainage systems, and roads.
