At the point 3, the compositions showed a complex situation, its contents chiefly ware B and N elements (atomic 84.52%) , it was substrate of CBN material; Co and W(atomic 6.9%) elements were the binders of CBN material; additionally, Ti, Al, and V(atomic 8.58%) was adhesive titanium alloy in tool rake face.

Several studies conducted by Ramadani et al. [11] and Chen et al. [12] have shown that solid waste material such as WGP has chemical composition and physical properties comparable to traditional supplementary cementitious materials and can be successfully used to create blended cements which can improve workability, early and long term strength and durability.
However, Rahma et al. [18], confirmed that increasing the fineness and the glass powder content has a negative effect on the workability of the mixture.
Omran et al. [21] reported that the use of glass powder in the cement matrix resulted in a decrease in both water absorption and porosity.
Rahma et al. [18] reported similar results that as the content of glass powder increased, slump flow decreased.

Booker[4] et. al. used Australian zeolite to study the saturated ion exchange capacity of zeolite, and the result was: 4.5mg/g.
From the figures we can see that before the sample absorb ammonium cations, there are Al, Si, C, O, and Na on the surfaces.
Al ions), and inter-layer cations.
This indicates that after modification, the Si-O tetrahedral and Al-O octahedral structures are severely damaged, resulting in significant changes in the flexural vibrations of Si-O and Al-OH, which may even become difficult to detect.
