The Mechanism of Mineral Admixture in Cement Hydration Meili Zhao Department of chemistry and chemical Engnieering of Weifang University, Weifang, Shandong 261061, P.R.
Because of zeolite in the mineral admixture, worm-like hydration products in the hydrates formed, which the active component in the zeolite reacted with Ca(OH)2 of cement hydrates to form C-S-H gel. [7] The density of the cement structure after 28ds was more dense than 7ds’.
With hydration, C-S-H gel increased，single molecules of hydration products became increasingly difficult to distinguish, they are intertwined.Cement became more dense, this could make the compressive strength of the concrete higher than before.For the cement paste with mineral admixtures, at the early hydration of cement, the cement firsly generated hydrates of C-S-H gel and Ca(OH)2 crystals.The fly ash and slag particles were wrapped by hydrate products,while the force of hydrate and the particles was weak.with the hydration,mineral admixture gradually took part in the reaction,they reacted with the Ca(OH)2 to form lots of C-S-H gel.Lots of C-S-H gel filled in the gaps of the particle which did not react.Some of them was interwined.Then the structure of the cement paste got more dense.So the cement paste with mineral admixture had more compressive strength than the pure cement paste in the later hydration.

Polymer introduced in ionic liquid structure is equipped with special performance for functional polymer materials, such as gas absorbent, electric conductance materials, surfactants, carrier.
Now the papers of The influence of Poly Lactic Acid’s crystalline behavior and the compatibility by Poly(ionic liquid) are little, unique phase structures have not been reported.
PIL and PLA have a very poor compatibility and are soluble in different kinds and volatility of solvents to obtain different phase structures.

In 1999, as one of the first results in the endeavour of searching for new nitrides at high pressure, cubic γ-Si3N4 with spinel-type structure was realized by high-temperature/high-pressure chemical synthesis.[2] More successful examples for a high-pressure chemical synthesis of new binary nitrides followed with the discovery of Hf3N4 and Zr3N4, both adopting the thorium phosphide structure characterized by 8fold coordiation of the metal atom by nitrogen.[3] Hence, while the preparation of C3N4 itself was not successful up to date the high-pressure synthesis of a γ-Si3N4 indeed produced a very hard compound, measured and predicted to be the third hardest compound after diamond and cubic boron nitride.(1,2) Interestingly enough, only one attempt was made to synthesize solid solutions between Si3N4 and C3N4 utilizing high-pressure synthesis techniques.

The strong distance dependence of the FRET efficiency has been widely exploited in studying the structure and dynamics of proteins and nucleic acids, and other biomedical researches [2].
Previous researches indicate that the rupture degree and the digestion rate of the phospholipid bilayer are the key impact factors of the drug-loaded release, and the drug release is closely related to the change of the structure of lipid membrane [3].
The NIR FRET system could be a fluorescence probe for the investigations of structure change of lipid membrane both in vitro and in vivo, which laid a foundation for the drug release research from liposomes.

Fig. 1 The FT-IR spectra of a: the un-treated cotton fabric; b: the cotton fabric modified by NaOH ; c: the cotton fabric modified by ionic liquid with NaOH. 3.2 Microscopy determination The cotton fabric was determined by the microscopy determination to investigate the surface structure of the modified cotton fabric by ionic liquid and the photographs were shown in Fig. 2.
The photograph indicated that after cotton fabric was modified the surface structure of the cotton fabric varied and ionic liquid adhered on the surface of cotton fabric.
After the cotton fabric was modified by ionic liquid the decomposition temperatures of cotton fabric didn’t almost vary, however the decomposition temperatures of the modified cotton fabric with NaOH was obviously reduced, which indicated that the structure of the modified cotton fabric with ionic liquid didn’t changed.

The crystalline structure of the tungstates is dependent of the ionic radii, where larger radii improve the scheelite structure, while the smallest radii improve the wolframite structure [3].
In an attempt to obtain tailor-made structures, many works have reported different processes to produce metal tungstates [3-5].
