Birefringence - Wikipedia

Birefringence is the optical property of a material having a refractive index that depends on the polarization and propagation direction of light. These optically anisotropic materials are said to be birefringent (or birefractive).The birefringence is often quantified as the maximum difference between refractive indices exhibited by the material.

sintering | metallurgy | Britannica

sintering, the welding together of small particles of metal by applying heat below the melting point. The process may be used in steel manufacturing—to form complex shapes, to produce alloys, or to work in metals with very high melting points. In a steel-sintering plant a bed of powdered iron ore, mixed with coke or anthracite, is ignited by a gas burner and then moved along a traveling grate.

Using Fly Ash in Concrete - Precast

When portland cement reacts with water, it produces a hydrated calcium silicate (CSH) and lime. The hydrated silicate develops strength and the lime fills the voids. Properly selected fly ash reacts with the lime to form CSH-the same cementing product as in portland cement. This reaction of fly ash with lime in concrete improves strength.
