The thermal insulation materials form integral part of all constructions in civil engineering.
Variations in environmental temperature, relative humidity and atmospheric pressure take a considerable share in the behavior of the materials built in engineering structures and influence their features.
Simulation Model of an engineering structure envelope was made in order to check the behavior of the developed materials in the engineering structure in practice.

Research on the Key Technology of Precision Injection Molding Equipment for Light Guide Plate XIE Pengcheng*a, GOU Gang b, WEN Zhenxing c, DING Yumeid and YANG Weimine Mechanical and Electrical Engineering College, Beijing University of Chemical Technology, Beijing 100029, China a xiepengcheng@gmail.com, bgougang1986@gmail.com, c2006000610@grad.buct.edu.cn, d dingym@mail.buct.edu.cn, eyangwm@mail.buct.edu.cn Keywords: Light guide plate, Injection molding, Screw, Surface treatment, Stripping performance Abstract.
The influencing factors of coating and PC materials' stripping were analyzed.
Plating layers on all the corners and edges of the screw tip were desquamated, and large areas of degraded materials were presented on the sharp top and at right angles of channel of the screw.
Coatings on the screw's body were intact and no degradable materials were deposited.
Screw head's coating performed well, and there were intact layers and no degradable materials on the entire screw.

An experimental study was carried out to investigate the force in drilling of engineering ceramic with a brazed diamond tool.
When these hard and brittle materials are used for mechanical structural parts, the need to cut or drill them is inevitable.
Compared with many researches in the grinding field, the engineering ceramic drilling was littler discussed by researchers [1-3].
Among these, the grain machining has been widely used because of fewer restrictions in the materials and cost efficiency in facilities.
So brazed diamond tools are taken as the best one to machine hard and brittle materials.

Hygrothermal Behaviour of Inorganic Binder-Based Board Materials Jan Bubeník1,a*, Jiří Zach2,b 1,2Brno University of Technology, Faculty of Civil Engineering, Centre AdMaS, Purkyňova 139, 612 00 Brno, Czech Republic abubenik.j@fce.vutbr.cz, bzach.j@fce.vutbr.cz Keywords: Inorganic binder, cement, gypsum, board materials Abstract.
There are some key problems with wood-based materials that complicate their use in the construction industry, such as hygroscopicity, inhomogeneity, anisotropy and flammability (reaction to fire in class F).
Commercially available board materials based on inorganic binders of comparable thickness (15 mm) were used to determine key properties.

The effect of glass powder on strength and microstructure of ultra high performance cement-based materials was investigated in this paper, which aimed to provide an additional option for glass recycling and potentially reduce the high costs of this kind of materials.
As one of relatively new kinds of building materials, ultra high performance cement-based materials and their derivatives have been widely used in many areas including industrial and civil buildings, nuclear waste storage facilities, railway construction and so on nowadays.
These new materials are developed through micro-structural engineering and offer a combination of materials and performance characteristics.
