Graphene Oxide was synthesized according to the modified Hummer’s method as described by Paulchamy et al. (2015) [15].
The linear form of the Freundlich equation can be expressed in the following equation as described by Boparai et al. (2011) [18]:
Moreover, a study by White et al. (2018) stated that precipitation of copper as Cu(OH)2 is more likely to be dominant than Cu(II) ions as pH>7.

Wouterson et al. [3] reported a different trend in the values of Etρ which is subject to the type of microsphere used, a linear increase in Etρ was observed for K46 type of microsphere, whereas K15 microspheres show a constant trend with no noticeable increase in the value of Etρ but the phenolic microspheres decrease in Etρ as the volume fraction of HGM increases.
Wouterson et al. [3], also reported a similar case whereby the σf/ ρ was maximum at the concentration with the highest HGM volume fraction.

Al-Kroom et al. [17] also indicated that adding crushed clay bricks improved the durability of structurally recycled lightweight concrete.
Moreover, Ahmad et al. [9] concluded that plastic aggregate weakens concrete, but plastic fibers can enhance its durability.
In this work, CEM I 52.5 Portland cement is produced by El-Aresh Company Egypt, and its tests were confirmed to comply with BSEN197/1 2011 [37] and ESS ES4756/1 2013 [38].
HRWR has a specific gravity equal al 1.09, and it meets the requirements according to ASTM C 494 Type G [42].

Based on the research on the contents and features of eco-civilization construction, Song(2008), Chang(2009) and et al chose three levels with several indices in each level to construct the indexes system of evaluating the socialism eco-civilization, and then calculated the weight of three-class index by use of AHP method after asking the experts for advice[2] [3] [5].
Based on the PSR model, He and at el (2011) designed the four-class frame structure of system-goal-criteria-index to construct the evaluation indices system comprising 30 indexes in four aspects as the status of urban eco-civilization, pressure, renovation and support, and then comprehensively evaluated the eco-civilization construction level of Changsha city in Hunan province during the year of 2005-2009 by use of entropy evaluation method[7] [8] [9].
