AB  - New eco-friendly thermal-casting ductile CPNC-concrete and CPNC-mortar materials 
      have been developed without Portland-cement or water-use. It needs three hours 
      for thermal synthesis. It contains 5%, 10% or 15% green natural nanoclay-polymer 
      nanocomposite CPNC as a bonding-agent instead of Portland-cement for mixing with 
      sand and crushed-stones by heating at 250  degrees C in electric ovens. CPNC is a dry 
      powder consisting of 5% montmorillonite (MMT) nanoclay and 95% high-density 
      polyethylene (HDPE). The study includes mixing, thermal synthesis, mechanical, 
      fracture, and ductility property testing, and characterizations of the chemical 
      composition, microstructure morphology and homogeneity using EDAX, SEM and XRD. 
      It has new properties, such as a homogenous-microstructure with bonding, 
      self-compaction abilities, no-cracks, ductility, good compressive and tensile 
      strengths, and good fracture properties. It does not exhibit steel corrosion; it 
      has rapid processing, no-water curing, low-density, no-shrinkage cracks, 
      no-sudden failure, no-pollution utilizing a new manufacturing technique. 
      CPNC-concrete is developed to stop the Portland-cement industry problems, to 
      produce a clean and green environment without Portland-cement damage for human 
      beings and to conserve drinking water. It has potential for different 
      applications in construction, and it is suitable for 3D techniques with fast 
      construction. Furthermore, this material requires new special codes for design 
      and construction.
