A filter for molten metal is an open-pored porous material comprising particles of refractory material embedded in and bonded together by a carbon matrix bonding material. The filter can be made by forming a porous article from refractory particles e.g. refractory oxide carbide or graphite and a carbon-rich binder e.g. tar pitch or an organic (preferably aromatic) polymer that degrades to

Thermal ExpansionStress and Force
Thermal ExpansionAxial Force Calculator Linear expansion due to change in temperature can be expressed as. dl = α l o dt (1). where . dl = elongation (m in) α = temperature expansion coefficient (m/mK in/in o F) l o = initial length (m in). dt = temperature difference (o C o F) The strainor deformationfor an unrestricted expansion can be expressed as

Modulus of Rupture (psi kg/cm 2) Modulus of rupture (MOR) is like a three-point bend test. MOR measures the bond strength of the test specimen. For castables it measures the bonding strength of the cement matrix. The particle size and packing of the aggregate system are factors in MOR but the maturity of the cement bond contributes more to

A Study on Residual Compression Behavior of Structural
Fire ranks high among the potential risks faced by most buildings and structures. A full understanding of temperature effects on fiber reinforced concrete is still lacking. This investigation focuses on the study of the residual compressive strength stress strain behavior and surface cracking of structural polypropylene fiber-reinforced concrete subjected to temperatures up to 300 °C.

Microstructure characteristics including hydration product and pore structure are also studied. The results show that adding MK and SF instead of 4 6 and 8 fly ash (FA) reduces flowability of SCC this is due to the fact that the specific surface area of MK and SF is larger than FA and the total water demand increases as a result.

What is Thermal ConductivityDefinition
The heat transfer characteristics of a solid material are measured by a property called the thermal conductivity k (or λ) measured in W/m.K. It is a measure of a substance s ability to transfer heat through a material by conduction. Note that Fourier s law applies for all matter regardless of its state (solid liquid or gas) therefore
