The negative environmental impacts of Portland cement as a binder in the construction industry have created growing impetus to develop sustainable alternative binders. Various types clay been considered potential replacements. impact clays replacement depends on dosage and treatment methods. This paper presents comprehensive review determine effects different fresh hardened properties concrete ...

A variety of geomaterials, such as cementitious or clay-based materials, has on the nano-scale a layered microstructure that can contain fluid in its nano-porous space. The creep of such nano-scale basic units is what causes the macroscopic creep. Here, one nano-pore whose walls consist of two parallel infinite solid layers interacting through Lennard-Jones potential is studied. The authors eva...

Abstract Cold recycling of asphalt is an effective solution to reduce the environmental impacts pavement construction and operation. This approach reduces use scarce resources fossil fuels, prevents spread greenhouse pollutants in air. Despite its benefits, recycled does have drawbacks, some which include nibbling, stripping, less resistance fatigue. The additives can improve mechanical propert...

This work presents the effect of synthetic procedures (extrusion and casting) on the dispersion characteristics of nano layered silicate clay particles in the polypropylene (PP) polymer matrix. Three different molecular weights PP samples are taken and filled with nanoclay of 1 wt% and 3 wt%, and these nanocomposites were synthesized by using an extrusion or casting methods. The X-ray diffracti...
