Although glass spheres are classified as nonreinforcing fillers, the addition of 40 g of these spheres to 60 g of nylon 66 increases the flexural modulus, the compressive strength, and the melt index of the polymer. The tensile strength, the impact strength, the creep resistance, and the elongation of these composites are less than those of the unfilled nylon 66. 

Equation (20) and the deviation of the index n from the uniform-bonding value of 2 have been used to interpret compressive strength data for wet and dry iron ore balls [55] and for fertilizer granules [56]. 

An alternative method to quantify the brittleness of a seal rock uses the unconfined compressive strength derived from sonic logs. This method uses the brittleness index, BRl= UCSIUCSf c, where t/CS c is the unconfined compressive strength of a normally consolidated rock. UCS can be measured directly or is estimated from logs based on empirical correlations using the equation... 

The mixing index is related, in some cases at least, to the physical properties of the mixed material. For example, the compressive strength of clay samples stabilized with portland cement has been related to the value of 7p. Low strengths were indicated when the value of Ip was small high values of Ip corresponded to extraordinarily high strengths of the stabilized samples. 

The compressive strength of a cement-stabilized clay sample from a small two-arm kneadcr varies with mixing index according to the relation ... 

Processing production of coal sample and physical mechanic parameters test are in strict accordance with the provisions of Measurement method of coal and rode physical and mechanical properties (GB/T 23561-2009), and Measurement method of coal seam impact tendency classification index (MT/T 866-2000). The experiment determined natural apparent density, compressive strength, consistent coefficient, elastic modulus, deformation modulus, wave velocity, rock burst energy index, elastic energy index, dynamic failure time, and other parameters. The determination results as shown in Table 1.

Diamond s combination of properties make it a unique material. Although hardness is its primary characteristic, thermal conductivity, compressive strength, refractive index, spectral transmittance, and chemical stability are either the highest or among the highest found in nature.
