At this time, the physical and mechanical properties of reclaimed rubber, such as tensile strength, tear strength and elongation at break rate, is the best.
By simulation analysis and experimental studies, using new twin-screw extruder to achieve the regeneration of waste tires has some main factors that affect the regeneration, such as screw speed, reaction temperature and screw configuration.
When the screw speed changes in the range of 60 ~ 90r/min, the physical and mechanical properties of reclaimed rubber is better
When the reaction temperature changes in the range of 170~210℃, the physical and mechanical properties of reclaimed rubber is better.
Too high or too low screw speed and reaction temperature will lead to the physical and mechanical properties of recycled rubber decreasing, thus affecting the performance of the use of reclaimed rubber.

Latest developments in nanosciences introduced a new generation of nano-sized
materials possessing often remarkable mechanical and physical properties.
Nanosilica enabled an immense densification of the hydrated binder matrix, which in turn improved for instance the durability and mechanical properties.
Addition of nanosilica causes further densification of the binder matrix and thus enhancement of the mechanical properties.
As a result, the CNF acted as weak carbon inclusions which decreased the homogeneity of the binder matrix, increased the water uptake (one of the detrimental factors for frost durability of concretes) and worsened the mechanical properties.
Summary Incorporation of nanosized materials, in this case carbon nanotubes, carbon nanofibres and nanosized silica has affected the mechanical and physical properties of Portland cement based mortars.

This paper established the ternary compound system of PC/PLA/ABS by melt blending and studied the impact of adding ABS and compatibilizer ABS-g-MAH on the composite’s morphology, thermal properties, rheology and mechanical properties.
In addition, ABS-g-MAH effectively improved the compatibility of the composites as well as mechanical properties of materials.
Mechanical properties were tested by the universal mechanical tester (provided by SUNS Company of Shenzhen), and notched impact strength in mechanical properties was tested according to GB/T 1843-96 standard.
Therefore, taking all factors into consideration, the appropriate ratio of ABS should be 30% of PC / PLA mass.
The experiment tells us that ABS has an influence on the system's thermal properties, mechanical properties and rheological properties.

In oil drilling the failures of PDC drill bits are exhibited as erosive wear, dropping and
breaking of cutters, so the erosion and corrosion resistance of the matrix is one of the key factors
affecting the quality of PDC bits.
The erosion and corrosion resistance of PDC matrix is one of the key factors affecting PDC bit's quality except for the quality of PDC itself [2].
Their properties are shown in Table 3.
