The aggregates used were adjusted as to avoid gap-grading and Table 2 showed the grain size distribution and passing percentage of aggregate.
DS was calculated by the following equation: In which, N is the number of wheel loading cycles per minute, d60, and d45 are the rutting depths measured at 45 and 60 min, respectively.

A number of recent articles investigating the mechanical properties of friction stir welds [2-4]
and a laser weld [5] have reported that digital image correlation (DIC) is an effective technique for
the measurement of the local variations in stress-strain response across the weld.
This is due to the large columnar grain structure observed in the weld metal by metallography.

However, many factors such as the type of ores processed, the type of furnaces and the cooling methods influenced the mineralogical composition and phase grains within copper slag [1].
CaCO3= CaO + CO2 (1) CaO + H2S = CaS + H2 O (2) CaO + MS = CaS + MO (3) C + CO2 = 2CO (4) This paper copper smelting slag SiO2 Content of 34.90%, a large number of iron and SiO2 combining to form iron olivine ( 2FeO∙SiO2), was used as raw material.

As shown in Table 1, the different series of PEDOT:PSS own conductivity, which obviously increases with respect to the series number, while the Seebeck coefficient is maintained for the first two series (PH500 and PH750).
It is because the grain size and shape together with the properties of the contact have a great influence on the transport characteristics of the semiconducting films [12].

In powder metallurgical, sintered magnets are manufactured from fine powders with grain sizes in the range of a few Micrometres.
They undergo a large number of energy-intensive process steps, such as compacting the magnetic powder in the magnetic field (up to 1000 MPa), long-lasting sintering at very high temperatures (above 1000°C) or subsequent post-processing for shaping. [1; 2; 3] Additive Manufacturing as an Efficient Alternative for Magnet Production The Additive Manufacturing (AM) of NdFeB magnets is currently the subject of various research projects focusing on different process technologies and alloy compositions.

Introduction
Concrete, being far from being a “young” material, in terms of its potential and capabilities, to this day remains the most popular and widely used composite, since at all times and in the future it will occupy a leading place among the huge number of its relatives used in the buildings and structures construction process [1,2].

An ac susceptometer from Cryo Industry model number REF-1808-ACS was used to determine the susceptibility from 30 to 300 K.
For all x, the particles composed a highly dense structure of average grain size between 2-3 mm.
