Introduction Nanometer material science is a frontier discipline, originated in the eighteen sixties research of colloidal particles.
Nanometer material science is to unite the interdisciplinary physics, colloid chemistry, coordination chemistry, chemical reaction kinetics, surface, interface and other disciplines, is an important part of modern material science, called in twenty-first Century for the material.

Industrial solid waste is Grade I fly ash, and we also use other self-made materials for stimulating fly ash's activity.
So, acicular materials can be asserted as ettringite.

However, the success of the simulation depends on the accurate identification of the constitutive parameters of materials, i.e., its calibration.

Physical and chemical properties of Paste Filling Material Physical and chemical analysis of the Filling materials
Adopting the fly ash of minmetals power plant as filling material, the concentration of paste filling materials with same fluidity will be lower, also the intensity of paste filling body with the same amount of cementing material will be relatively lower.
All of this is beneficial to improving the performance of the filling materials, therefore, the fly ash of HanFeng power plant or MaTou power plant is the preferred option for filling material.
Conclusions Coal mining technology of paste filling seems new paste cementing materials as curing agent.
