Commonly the fracture of the engineering materials used in micro cutting such as steel, 45 stainless steel, copper, aluminum and its alloys is often ductile fracture, the radius of cutting edge is from several microns to several microns in micro cutting, the size of grain in most of engineering materials is between 100 nm and 100 microns, the size of grain boundary is several micrometers, so tools is cutting in grain boundaries, the style of fracture is transgranular fracture.

Introduction In construction, the search for new high-performance building materials, in particular from natural raw materials, like cane, is increasingly being explored.
Raw samples are classified with flammable materials (B3).
According to research results, fire retardant materials belong to combustible building materials of moderate flammability (G1), while raw materials are classified as building materials of high flammability (G4).

Review of Research on Conductive Cement-Based Material Te Li1,a*, Laire Tier2, b 1Faculty of Materials Science and Engineering, Chongqing University, Chongqing 400000, China 2Faculty of Materials Science and Engineering, Southeast University, Nanjing 210000, China alairetier@seu.edu.cn, bTeLi@cqu.edu.cn Keywords: Cement-Based Materials; Electrical Conductivity; Nanomaterials Abstract.
In the study of conductive cement-based materials, the size and shape of conductive materials have a direct impact on the electrical conductivity of cement-based materials.
Effect of Conductive Materials on Conductivity Long ago, steel fibers were added to cement-based materials to increase the conductivity of cement-based materials[23].
Some studies have also added industrial waste to cement-based materials to improve the conductivity of cement-based materials, Vasudevan [39] added copper slag to cement-based materials, effectively improving the conductivity of cement-based materials.

Pure silica mesoporous materials possess a neutral framework, which limits their application in catalysis.
To obtain materials with potential for catalytic application, it is necessary to modify the nature of the amorphous walls by incorporation of heteroelements.
The red shift idicates that heteroatoms are incorporated into the framework of mesoporous materials and Si-O-M bonds were formed[6].
