Introduction In recent years, the whole or part of numerous existing concrete structures cannot meet the normal operating requirements and need to be strengthened, remolded and repaired due to natural factors, man-induced factors, changes of operating requirements, updating of design codes, improving of emergency capacity, etc.
The mechanical property of composite strengthening not only depends on the individual properties of steel plates, reinforcing steel bars and concrete as well as the interactions between them, but also is affected by the properties of steel plates and concrete as well as the new-to-old concrete interfaces.
The results show that composite strengthening can more effectively enhance the bearing capacity of bridges and improve the mechanical property of bridges.
Given the long-term safe operation factor of the structure, the strength and rigidity analysis results and economic factors, it was planned to employ composite strengthening (Refer Fig. 1) to the beam being severely burnt and employ bonding steel plates to the beam being slightly burnt.
The strain of the steel plates used to strengthen the bottom slab of beams is asymmetry and part of the strain verification coefficient approaches to 1, which shows that the composite strengthening can ensure that the new and old structure can be stressed as an integrity and co-acted in a good condition; However, the mechanical performance of the original beam concrete would not be changed significantly after being strengthened with bonding steel plates, the strength of the original beam concrete is relatively poor and the combined mechanical performance of the original beam structure and steel plates is relatively weak.

Introduction: Over the last two decades, the use of geopolymer materials has attracted much attention as a new environmentally-friendly engineering technology due to their excellent mechanical properties.
The increase in strength was affected by the increase of the duration of the curing periods.
However, the Activator/FA ratio appears to be the most important factor that controls the strength development of the geopolymers.

Introduction Due to the excellent mechanical properties in terms of strength, hardness, and elastic response at room temperature, bulk metallic glasses (BMGs) have recently attracted great interest [1].
These non-equilibrium BMG alloys generally show, however, highly time-dependent deformation characteristics when exposed at high temperature in an undercooled liquid region even below the crystallization temperature producing significant property changes from the original amorphous characteristics [4, 5].
It is worth to note here that metallurgical changes such as structural relaxation or material flow during forming processes are well-known as a major factor affecting the forming efficiency prescribed by eq. (1) in terms of J value.
The SEM images of fracture surface obtained at these points are shown in Fig. 7 to clarify the main factors causing for total rupture.
The region of η>0.8 is found to be affected also by the prior heating rate before forming process due to the timedependent deformation characteristics, typically exhibited in a supercooled liquid region of non-equilibrium BMG alloys.
