Fly ash contains 25-30 % crystalline matter and the rest are amorphous (glassy) materials and unburnt carbon particles [5,6].
Results and Discussion XRD studies revealed that the predominant phases of test materials sintered at 1000 °C were anortite, cristobalite and hematite.

If the waste concrete is processed into renewable aggregate materials which is suitable for pavement use, and its nature can achieve way-use requirements, this would be a very effective methods to solve the waste concrete.
The researchers of Australia Griffith university crushed the old concrete whose compressive strength is 15 ~ 75Mpa, and then combined the graduation which accords with the requirements of sub base materials.
Semi-rigid material is a stress sensitive material, compared with asphalt, semi-rigid base material fatigue curve is more flat [10].

Carboxylic groups were firstly introduced to MWCNTs by oxidation in a mixture of sulfuric acid and nitric acid, and the NAD moistures were further attached by the formation of amide bonds with carboxylic groups under the help of 1-ethyl-3-(3-dimethyl-aminopropyl)carbodiimidehydrochloride and N-hydroxysuccinimide, which resulted in the coenzyme functionalized materials, MWCNTs-NAD.
In recent years, the electrochemical oxidation of NADH on electrode modified by nano-materials, especially carbon nanotubes (CNTs), received great interest.
In this article, a coenzyme functionalized material (MWCNTs-NAD) was prepared by linking NAD+ to the surface of MWCNTs.
Materials apparatus Multi-walled carbon nanotubes (MWCNTs) were purchased from Beijing Nachen S&T Ltd., and NAD+, NADH, NAD-dependent alcohol dehydrogenase (ADH, EC: 1.1.1.1 from Saccharomyces cerevisiae, 450 U mg-1), 2-(N-morpholino) ethanesulfonic acid (MES), N-ethyl-N’-(3-dimethyl-aminopropyl) arbodiimideydrochloride (EDC), and N-hydroxysuccinimide (NHS) were obtained from Sigma.

Polymer-based materials dilate upon absorbing moisture.
Differential swelling occurs along the interfacial of two materials and hygroscopic strains arise due to mismatch of CME.
Polymeric materials transport moisture primarily by diffusion which can be analogically modeled in standard Fick's transient diffusion equation in Eq. 1

Introduction Polypropylene (PP) film ranks the second in flexible packaging materials consumption due to its excellent performance, it also take approximately 30% in composite flexible packaging materials [1~3].
To solve the above problems, ordinary PP flexible packaging materials were modified by self-made nano-SiO2 agent, the results showed that the properties of modified PP including polarity and crystal structures has changed largely, thus its mechanic property, printability and composite performance has improved and meanwhile made PP materials meet the requirement for food packaging because modified PP materials reduced its solvents residue of ink and adhesives in flexile packaging materials.
