The aim is to harmonize the data and understand the meaning of the different values gathered.
The priority is to acquire and improve knowledge concerning: · The validity of the thermodynamic calculations, the improvement of the data bases and the calculation protocol
To induce the industrial users of refractories, from different horizons to join forces with the networks to focus on problems to be solved with the expected new process to be put in place, whether it will be related to cost reduction, or to more ecological or sustainable processes, more energy intensive or using less total amount of energy. 2.

The data is got by using origin Pro 7.5 software analysis, and it can get the maximum absorption peak wavelengthλ max.
The three characteristic peaks solution absorbance scan curve of MRλ max1=362nm,λ max2=426.5nm are located, λmax3=585nm, then the comparison, in the water after the addition of HBS-1, methyl red three in water absorption maxima peak blue shift occurred in high frequency, low wavelength (lambda max<500nm) wavelength value reduction 4 ~ 6nm, while in the low frequency and high wavelength values (λ max>500nm) wavelength value trend is very obvious, the reduced 30nm.
The absorbance scan curve C precipitate is lower than that of D curve, data indicating the changes of absorption solution of the maximum position, three the maximum absorption peak position respectively intoλmax1=364.5nm, λmax2=427.5nm, λmax3=583.5nm, these three figures and aqueous solution of MR three characteristic peaks of absorbance values were almost the same (lambdaλmax1=362nm, λ max2=426.5nm, λmax3=585nm).

During the experiment, pore pressure transducers were used to measure the pore pressure at the inflow position caused by the water flow, meanwhile recorded by a data logger.
When enough data was collected, permeability was calculated by using Darcy’s law by k = (Q·γw·L)/A·p, where k is permeability, Q is quantity of water discharged per unit time, γw is unit weight of water, A is cross-sectional area of the sample, L is length of the sample, and p is pore water pressure at the inflow position.
Minor reductions occasionally observed at ~7 and 14 days were linked with the drying out of samples, which can reduce the formation of HMCs due to the lack of necessary water content for the continuation of carbonation at longer curing periods.

The data analysis was performed using IBM SPSS Statistic version 20.
The t- test and analysis of variance (ANOVA) followed by Duncan's multiple range test were applied in the data analysis.
For antioxidant activity, the presence of functional groups such as hydroxyl and carbonyl in soluble compounds leads to a reduction or inhibition of oxidation [35].

All prisms were marked and photographed three months after de-tensioning, to reach stable and representative cracking data.
Figure 30: Mix#3, ⅝in Concrete Cover-Crack Length (in) Figure 31: Mix#3, ½in Concrete Cover-Crack Length (in) The influence of the thickness of concrete cover on the bond performance between steel and prestressed concrete is clearly indicated in Figure 29, Figure 30, and Figure 31, where crack length is seen to increase with the reduction of cover thickness.
Based on the analysis of current test data, it was found that the shallow chevron type of wires performed better than wires having deep chevron shape.

Equally whether TRC-components with a one-dimensional or two-dimensional reinforcement structure or complex and free-formed 3D topologies with three reinforcement directions, they all assist to achieve the significant reduction of CO2-emissions in order to comply with the federal guidelines.
Overall, the botanic-oriented fiber alignment, the finite element method (FEM) based designing and the optimizing algorithms used to generate the robot placement paths (machine control data) are taken into account in the development process.
Subsequently, the robot-supported manufacturing technology can produce the 3D textile reinforcement structure (G) by means of generated machine control data.

By employing experimental pore size
distribution data, the Johanson-Stewart equation gives more realistic results.
Some of the above probability distribution functions have one parameter, while others have two parameters, to adjust and fit with experimental data.
A sharp decrease in effective diffusivity can be observed upon increasing σ up to 5; after that point, the reduction in effective diffusivity is low.
