The main factors that control the rheology of castables are the particle size distribution, the solid concentration, and the nature of the raw-materials and chemical additives present in the system.
Therefore, the right choice of dispersing agents is very important for the systematic development of these materials [6].
The tests were performed in diluted suspensions (30 vol.%) containing the matrix materials.
Corundum-spinel castable were subsequently prepared using white fused alumina as aggregates and other materials as the matrix constituents (as shown in Table 3).

In summary, the SF /xylitol film containing 10% xylitol provides a great potential to act as repairing materials for cornea.
Now collagen was extensively used for corneal tissue engineering as scaffold materials.
So it is necessary to find new materials for corneal tissue engineering scaffold.
Their application for cornea tissue engineering materials were studied.

Abstract.
Experimental (1) Materials; Commercially pure titanium (Cp-Ti) disks with diameters 15mm and 1.5mm thickness were polished with 800# SiC sand paper, and then sandblasted with 200~500µm corundum and acid etched in 67% HCl/H2SO4(1:1) at 80 °C to get the well-known SLA surface.

Mix
No.
Since most national Codes express the modulus of elasticity as a function of the concretate compressive strength observed with compression tests, these expressions will only be correct if the most common mix designs and materials are selected [1].The mixes for HPC in this study is based on supplementary fly ash, super plasticizer, a low water-to-cementitious materials ratio, and carefully selected aggregates.
