investigating the microstructure and mechanical properties of metakaolin-based polypropylene fiber-reinforced geopolymer concrete using different monomer ratios

investigating the microstructure and mechanical properties of metakaolin-based polypropylene fiber-reinforced geopolymer concrete using different monomer ratios

researchers have focused on the fabrication and implementation of concrete that has optimal characteristics, logical price  with minimum harmful impacts on the  environment. for this  purpose, the current  project  was conducted.

geopolymer  cement,  due  to  its  high  durability,  insignificant  energy  consumption,  least  co2 emissions, acceptable investment cost, and specific characteristics, is accounted as a new class of mineral binders which is different from such binders as portland cement. in this research, the geopolymer concrete was  made  using  metakaolin  precursor containing  0.3,  0.5,  and  1%  polypropylene  fibers  together  with monomer with 2, 2.5, and 3 ratios.

next, a number of engineering properties such as the bending strength, compressive strength, electrical resistivity, water absorption, and microstructure were assessed at 90 days age using the electron microscopy scanning method.
