Materials and Methods The effluent flow from feldspar processing was 126 m³/h (total solids = 7.3 wt%, mean total solids = 9,576 kg/h, d50 = 28.47 μm).
The crystalline phases present in the materials were analyzed using an X-ray diffractometer (XRD; Shimadzu XRD6000, λ = 1.5406 Å, 25 kV, 25 mA, 2θ from 3 to 80˚, 2˚/min).
According to Tavares, Castañeda, and Soares [8], high L.o.I. indicates a high loss of volatile compounds and organic materials contained into the mineral structure.

In this study, firstly we have established 10kW 3D model of wind turbine blades which has two layers of different materials (Carbon Fiber and viscoelastic material).
The figure shows that the proposed blade model is consist of two parts, i.e, Carbon fiber material and viscoelastic material.

Experimental Procedure
2.1 Material
The reconstruction material was Höganäs amperprint 0717.074 - 316L stainless steel powder with an 8 g/cm3 density and was used to fill the damages.
It is worth to mention that the specimens were machined from laminated bar, that also justifies the hardness difference between the base and deposited materials.
Visually, there are no boundary marks between the base material and the new material, which makes the repair entirely satisfactory.

Experiment
Materials.The primary raw materials of the experiment were low rank fly ash, limestone, soda, dispersing agent systhesized in the laboratory and CO2.
The results of the orthogonal tests show that the calcination temperature and the ration of CaO/SiO2 are the main factors influencing the self-pulverization of sintered materials. the sintered materials, with the ratio of CaO/SiO2 as 2.5, was calcinated at 1260℃ for 1h, then cooled to 600℃ for 1h, finally can be self-pulverized completely.

Therefore in consideration of all factors, the strong bonding of geopolymer can be develop hence contribute to the maximum strength of materials.
In common, the study of geopolymer materials such as lightweight concrete, composite and bricks are performed.
There are some common raw materials used in geopolymer such as metakaolin, fly ash, slag, bottom ash, volcanic ash and rice husk ash [9][10][11].

Studied materials
The applied BA was collected in winter 2013 from an incineration plant situated in the Czech Republic.
Replacement was made according to the fraction distribution curves of siliceous sand and BA and bulk densities of the used materials.
Results and discussion Mechanical properties of the studied materials are described on the graphs and in the tables below.
