The RPE process performed in the samples is a refined version of the recipe adopted by El
Hadi et al. [16], where the substrate is immersed in an aggressive mixture of Li nitride, Na nitride
and K nitride at a concentration of (1:10:10) weight.

They are a chain structure formed on a back bone of aluminium (Al) and silicon (Si) ions and a member of the family of inorganic polymers.
Kasama et al. [33] quoted that several research also proved that in a wide range of cement content, 30% gave the higher value of unconfined compressive strength.
Kolias et al. [37] quoted that the higher amount of fly ash used increase the unconfined compressive strength of the soil.

It is stated by Pickering et. al.
Morphological and chemical analysis by Ashori et. al. [20] indicated that bast and core fibers were significantly different.
It is stated by Migneault et. al. that torque simulates real-life processing conditions.
Similar trend has been found by sobhy et. al. [16] when studied three different fiber size (i. e. <125 µm, 125-250 µm and 250-500 µm) of wheat husk fibers reinforced rubber composites.

In view of this practical standpoint, the effective use of nanoparticles relies on the ability to achieve uniform and stable dispersion (Jayapalan et al., 2010; Nazari et al., 2011; Sato et al., 2006; Sato et al., 2010; Chang et al., 2007; Gündoğdu et al., 2010; Shih et al., 2006; Jo et al., 2007; Nazari et al., 2011; Qing et al., 2007; Sobolev et al., 2009).
Moreover, many researchers have focused on nanoSiO2 and demonsrated its effectiveness on enhancing the early properties (Jo et al., 2007; Qing et al., 2007; Ji, 2005; Zegetosky et al., 2010; Pourjavadi et al., 2012; Kong et al., 2013; Senff et al., 2009; Lin et al., 2008; Ltifi et al., 2011; Lin et al., 2008; Kong et al., 2012; Stefanidou et al., 2012; Hosseinpourpia et al., 2012; Li et al., 2004; Quercia et al., 2012; Zhang et al., 2012; Hou et al., 2012).
And studies on nanomaterials show that nanoCaCO3 has a potential for offsetting these negative side effects, even at high replacement rates of by-product for cement (Sato et al., 2010; Péra et al., 1999; Heikal et al., 2000; Irassar et al., 2000; Kakali et al., 2000; Bonavetti et al., 2001; Ghrici et al., 2007; Lothenbach et al., 2008; Liu et al., 2012; Kim et al., 2012; Bentz et al., 2012; Makar et al., 2011; Sato et al., 2010; Camiletti et al., 2013).
