Introduction Concrete is widely used as a primary structural material in construction due to numerous advantages, such as strength, durability, ease of fabrication, and non-combustibility properties, it possesses over other construction materials.
Fire resistance and thermal behavior after exposure to a fire in the concrete structure depends on thermal and mechanical properties of concrete materials.
Materials and Methods Steel Fiber.
This is due to the steel fiber resist in concrete and there is a good bonding between materials and reinforcement that lead the crush occurred slowly.

The Deep Surface Rolling (DSR) technology can substantially increase the fatigue life of metallic materials due to the introduction of deep compressive residual stresses in the material surface.
Mechanical peening using steel shot, glass or ceramic beads has been demonstrated to improve the fatigue life of metallic materials, due to the compressive residual stresses introduced into the material surface to a depth of about 0.25 mm.

However, the increased open porosity is connected also with the increase of the absorbability of ceramic materials, which should be taken into consideration in a direct exposure of materials to atmospheric conditions.

Measuring the thermal conductivity of Sn-based alloys are vital since they are mainly used in soldering and temperature sensitive materials in sprinklers.
λ= Q4πd ∆Td ∆ln t (2.2) When measuring the thermal conductivity of the electrical conductivity materials such as metals and alloys, the electrical leakage from the hot wire to the sample has to be avoided.
To avoid starting convention in the oil bath, a cover made of the heat insulating material was put onto it in measurements.
In materials, both electron and lattice contribute to the thermal conduction properties.

ZnO oxide is a promising material for optoelectronics because of its wide and direct gap (Eg=3.4 eV).
Introduction Zinc oxide is a very important material in some technological applications.
The similarities between ZnO and GaN show that the semiconductor oxide is a promising material for optoelectronic [1].
The surface role is particularly important when these materials are ultrafine powders and the role played by grain boundaries is not well known, specially in the case of nanomaterials.

It is should be noted that semi-solid processing will become a important forming method of simple, high efficient, low cost and good quality in the fields of materials processing. 1.
Therefore, it is necessary to widen research on semi-solid materials.
Semi-solid materials have been characterized by wide temperature interval between liquidus and solidus.
Furthermore, the forming temperatures of semi-solid materials have a limited influence on filling ability of slurry [31,32].
It has demonstrated that semi-solid materials are suitable for formation of both casting alloys and forging alloys.
