In this regard, the need to identify fundamental factors affecting both the thermophysical and strength characteristics of the material is of interest, as it will determine the ways to control the lightweight concrete quality.
Thus, the common factors, affecting which it is possible to simultaneously change the heat engineering and strength characteristics of lightweight concrete in the right direction, thereby increasing the efficiency of products and structures, have been identified.
At the first stage of research, the common technological factors that affect both the strength and thermophysical characteristics of concrete were identified.
The influence analysis of the main variable factors on the corresponding indicators of concrete properties was carried out on the basis of the obtained regression equations with the graphic models’ construction.
Thus, the studies of lightweight concrete based on microspheres showed that a change in the basic properties of a given concrete from prescription and technological factors obeys the laws generally accepted in concrete technology.

PP is a thermoplastic polymer known for its favorable mechanical properties, such as high stiffness and good impact resistance.
By comparing the storage modulus and mechanical loss factor of PP and PP/CNT composites using DMA, one can evaluate the effects of CNT reinforcement on the mechanical properties and viscoelastic behavior of the composite.
These factors can collectively contribute to a quicker degradation speed compared to pristine PP when exposed to hot air conditions.

Determine the optimum sintering temperature and optimum whisker content, when the mechanical properties of the composite materials are the best.
Stomata are stress concentration sites, and often lead to reduced mechanical properties.
The main factors that impact flexural strength of whisker reinforced material are: the type of whiskers whisker content and sintering temperature, etc [3].
Generally the whisker aspect ratio is larger; the crack deflection is more significant, which help to improve the mechanical properties of the composites.
Meanwhile, whiskers dispersed unevenly, porosity increased, the material density decreased, resulting in decreased mechanical properties [6].
