All of them were analytical reagent (AR). 2 Experimental scheme In the experiment, pulverized coal ash, zeolite, fine sand, granular activated carbon, Fe and etc. were used as the activated materials of PRBs.
The activated materials were mixed and filled into special mesh bag and then fixed in porous plastic rectangle box as a modular unit to facilitate the replacement and addition of reactive material in PRB when it was saturated and invalidated.

Introduction Currently the natural materials become popular building material for houses, buildings and recreational property.
Fireproofing of combustible materials is a specific area of fire protection.
The target of fire-technical engineering and fire science is also the improvement and development of test methods for the examination and evaluation of materials [1].
In the field of fire science is the way how to make the combustible materials noncombustible the ambitious and challenging destination.
Due to environmental aspects, the use of natural insulation materials made of plant materials, namely hempen fiber, is becoming more popular.

On the other hand, the strength of crystallized materials decreased drastically to 220[MPa] by tension, and 560[MPa] by compression.
This result shows that the high strength of Zr55Cu30Al10Ni5 bulk glassy metal has a direct correlation to the atomic structure thus the strength of crystallized materials becomes very low while the strength of the materials maintaining an amorphous structure is high.

Dasgupta1,b 1 Mechanical Engineering Department Birla Institute of Technology and Science Pilani -333031, India a dileep.vnit@gmail.com b msdasgupta@gmail.com Keywords: gas cooler, CO2 refrigeration systems, material and energy saving Abstract: Carbon dioxide is one of the rediscovered sustainable options, as CFCs and HFCs are now in the list of regulated substances, to be phased out in time bound way.
However the approach is found to be inefficient not only from the point of view of excess material use but also from energy consumption and performance.

Abrasion tests were performed to contrast the wear resistance of two materials.
It requires materials with excellent high temperature wear resistance.
At present, the alloy is still accepted as a good material to apply in industry to prolong the life of the materials.
Materials loss is in a small range in the process of abrasion.
