Commonly, OPC concrete industries apply the conditions of high temperature and pressure to manufacture their products which cause the chemistry of hydration has been substantially altered.
C–S–H forms consequently are converted to crystalline structures α–calcium silicate hydrates (α–C2SH) which cause an increase in porosity and reduction in strength [8].
However, excess GGBS replacement in the OPC blending cause to porous structure thus increasing water absorption into the mortars.

The Specimen to be investigated are the properties of micro-structure of a given layer of titanium which then inserted into the machine outo fine coater JFC 1600 for 1 hour until the correct coating level of all surfaces has been investigated.
The decrease of stress is directly proportional to the high absorption of the composite during the immersion, the longer the absorption of the lower strength values stresses of GFRP composite materials. this is influenced by the swelling of the surface through saturation, resulting in damage on the surface and causing water logging in the composite structure.
The authors also would like to thank the Ibnu Sina Institute Faculty of Mathematics and Natural Sciences Department of Chemistry in the SEM testing.

PAH (Polycyclic Aromatic Hydrocarbon)is the hydrocarbon whose molecular structure contains more than one benzene ring.
For its simple structure , the changeable thermal parameters, turbulence parameters and ignition parameters easily, even analysis ability of the influence on the combustion process by way of changing a single parameters ,therfore，it is widely used in the basic research field of the internal combustion engines[3][4].

Among rare earth ions, trivalent europium (Eu3+) ion is the best candidate to be used as a probe to investigate the local structure, and Eu3+-doped materials are frequently used in photonic applications as red phosphors for field emission technology [6].
In this work, Eu3+ doped glass was synthesized, and their inner structure and luminescent properties were also studied.

In the structure of Semi-IPNs, the C-O stretching vibration absorption peak at 1236 cm-1 in initial PVA shifted to 1253 cm-1 and became stronger and broader, and the peak intensity of the dissymmetry stretching vibration of C-O at 1093cm-1 from initial PVA became weak because of the presence of PAA.
The FTIR spectra confirmed the presence of structure of semi-IPNs because new peak can not be found any more in the spectra of hydrogel (PVA/PAA).

A network-like structure was observed on the cleaned eggshell membrane surface, which indicates that the original eggshell membrane consisting of a complex lattice network of stable, porous and water-insoluble fibers [13].
The ESM is a complex porous structure made up of proteins, glycolipids, and carbohydrates, these macromolecules contain a large number of functional groups -OH, -COOH, and -NH2 etc. of eggshell membrane.

Zeolites with good physical adsorption and ion exchange characteristics are usually composed of hierarchical porous structures combining micropores with mesopores and/or macropores [7,8].
(The CT anthocyanidin was estimated in based on equivalence to delphinidin, its structure as shown.)
