The process of second scratch includes removing materials partial rupturing from workpiece, materials of workpiece surface and pushing and pressing chips.
It indicates fewer materials are broken during second scratch, while peak value improves for increasing of depth of cut and cutting area

Finally, taking both characteristics of basalt fiber and the increase of cement-based materials costs into account, it can be drawn that top priority should be given to the basalt fiber rather than to other fibers for cement-based materials.
Therefore,it is completely feasible to make up high performance cement-based materials with fibers.

The mosque's wooden materials total 313 pieces.This corresponds to the number of human bones.
Construction technology such as building materials that are effective (durable and sustainable) compared to before.
In the past, buildings were made with materials available nearby such as clay, stone, and wood.
However, currently, with technological developments, new materials are available that are more effective than before [59].
