This research effort aims to evaluate the mechanical properties of concrete with two aggregate type, light weight and normal weight at elevated temperatures.
According to previous research [1], the factors that influence the strength of concrete at high temperature divided in to two groups: material properties and environmental factors.
In addition, heat resistance of concrete affects by environmental factors such as heating rate, duration of exposure to maximum temperature, cooling rate, loading conditions and moisture regime.
Since aggregates make up the bulk of concrete, their properties largely determine concrete properties.
Overall results conclude that, aggregate type and loading conditions significantly affects the mechanical properties of concrete.

Cogullada 20, 50014 Zaragoza Spain aangel.fernandez@unizar.es, bmmuniesa@unizar.es Keywords: microcellular foaming, mechanical properties , shrinkage, injection moulding.
Complexity of microcellular injection molding is very high because the final properties of the material obtained depend largely on the processing conditions and these in turn unalterable factors such as mold design and manufacturing.
Knowing that the reduction of foam density implies a reduction of the mechanical properties and influences the final piece dimensions the conclusion is that the microcellular injection process has a very small process window to fit all these factors.
Second is the determination of mechanical properties which do not show a proportional reduction but exponentially with weight reduction components.

The factors that affect the mechanical behavior of structural planes are so complicated that it is quite essential to take an efficient method to quantificationally analyze these factors.
One thing needs to concerned is the complexity of factors affecting the structural planes mechanical parameters.
In order to combine the geometry and mechanical characteristics, there should be a valid method to comprehensively assess the effect of these factors.
Establishment of the Hierarchical Model Based on the existing results[7-15] from literatures about mechanical characteristics affected by various factors, considering the fundamentals of hierarchical model establishment and both the two aspects of structural planes features and external environment, the factors are classified and also the hierarchical model is established in Fig. 1.

Compression performance of pultruded GFRP (Glass Fiber Reinforced Plastics) can be improved by confined CFRP (Carbon Fiber Reinforced Plastics) sheet, but it was affected by some factors.
Different compression performances on different specimens were found in the experiments, so the influence factors should be studied.
Because of the discreteness of the strength parameters, the numerical simulation method was used to study the influence factors.
The ultimate fracture strain of CFRP sheet can be changed by the thickness of it when the mechanical property of single layer is certain.
Compression performance of CFRP sheet confined GFRP pipe is affected by the mechanical material property of GFRP pipe and CFRP sheet.
