Introduction The modern people who did not experience the extreme shortage of materials cannot imagine what kind of feeling of no food, which not like war, earthquakes, snowstorms that directly harm humans, but also deeply threaten each life, like strangling.

To study the influence of the material in the stress field, the results obtained out of two materials are compared.

Conclusions and Perspectives The geometrical ratio h/b=10 in the measurable zone of the specimen geometry seems to be the most performing since the stress error is less than 1% for the two materials.

The system has been designed from first principles and therefore can be extended to other materials and scaled up with slight hardware modifications. 22 A "low-cost" subtractive method for freshly finished 3D concrete printed structures is presented in the paper 23 In the paper, the feasibility of adding calcium carbonate and polymers to cementitious materials for spray-based 3D concrete printing is investigated in detail.
The considered works reflect the development of interest in the field of building materials science related to the control of the rheological and technological properties of dispersed building mixtures, the control of the kinetics of hardening of materials based on mineral binders, as well as the development of new materials. 3D concrete printing technology allows solving, on the one hand, the urgent problem of reducing the share of heavy manual labor in construction, and on the other hand, it can become a driver for the development of an affordable housing market created using new sustainable and environmentally friendly building materials with a low carbon footprint.
Ways to solve this problem can be determined by the existing infrastructure of the region, city, or country, as well as the characteristics of building materials that can be used.

Modified Sol-gel production of Nano SDC20 Materials S.
However, major constraint is the selection of materials for commercial SOFC, which are operated over a temperature of 1000 oC.
Performance of SOFC depends on electrolyte materials.
Cerium nitrate hexa hydrate Ce (NO3)3 6H2O,(Alfa acer, 99.8% purity) and samarium nitrate hexa hydrate Sm (NO3)3 6H2O (Alfa acer, 99.8% purity) were used as starting materials.

Estimation Model for Fatigue Life of Pipeline Steel with Mechanical Damage Yurong Jiang1,a and Meibao Chen2,b 1College of Petroleum Engineering, Chongqing University of Science and Technology, Chongqing 401331, China 2College of Safety Engineering, Chongqing University of Science and Technology, Chongqing 401331, China ajjcc540@163.com, b52053922@qq.com (corresponding author) Keywords: fatigue life, pipeline steel, crack initiation, crack propagation, mechanical damage Abstract.
This is due to a combination of good design, materials and operating practices.
Estimation Model for Fatigue Life of Pipeline Steel Hagiwara et al. [15,16] have been proposed an estimation formula for fatigue life of the steel pipe which was shown in Eq.2 (2) in which Nf is the estimated fatigue life; E is the elastic modulus of the materials; C, α, β, γ are the regression coefficients; d is the depth of dent; D is the pipe diameter; t is the depth of defects; T is the pipe wall thickness; and Δσ/E is the elastic strain range It can be seen from the Eq.2 that the estimated fatigue life sharply depends on the depth of dent, the depth of defects and the loaded stress amplitude, independent of the length of defects, the pipe diameter, the materials of the pipe and the hoop stress.

The apparent density of it is 2632 kg/m3 and its fineness modulus is 2.77; the size of the coarse aggregate is between 5mm and 20mm and the apparent density is 2719 kg/ m3; tap water is used in the experiment and its PH value is 8.73; fly ash produced by Sui Ning Thermal Power Plant belongs to high-quality Class I and its type is S95; the slag is ground granulated blast furnace slag produced by Cheng Du Concrete New Building Materials Co., Ltd.; additives are JX—GBNH1/1 high efficient polycarboxylate water reducer and solid high-performance erosion resistance preservatives (pumping)JX—GW2 which are produced by Si Chuan Superstar New Materials Co., Ltd..
Sulfate solution not only reacts with internal components of the concrete and generates expansile materials like ettringite and gypsum [4], but also separates calcium from C-S-H gel and even makes the gel have an apparent phenomenon of softening and segregation.
Therefore, lowering water-cement ratio, reducing the internal porosity of concrete and spraying coating on concrete materials can improve the frost resistance durability.
