However, because of the different materials of road, e.g., macadam, dirt, sand, and the effect of environmental illumination, there will be some features different from other road area in partial region.
The road in the scene is made up by different materials, therefore, different regions in the road show different gray values.

The basic material used for advancement in concrete is often composed of essential limiting materials such as concrete, fine aggregate, coarse aggregate, and water.
These issues with cementitious materials can be avoided by using a self-recuperating component.
Sodium silicate has a wide range of applications in cementitious materials.

Materials of building facades mainly include ganged brick and granitic plaster.
The occurrence of alkali corrosion is closely related to the nature and conservation status of building materials.
The restoration and strengthening of historic masonry structure walls should improve masonry and other porous materials through perfusing and solidifying materials, rather than simply replacing the materials.
Only accurately grasping the historic materials and reasons for structural damage can consider the specific climatic environmental factors.

Nowadays, people are more concern about replacing raw materials with renewable energy and hence, using waste to replace conventional materials.
The advantages of using kernel-shell as recycle materials are non-renewable materials can be replaced with renewable as well as encouraging utilization of renewable sources.

In recent years, stepwise graded materials, where the material properties vary gradually or layer-by-layer within the material itself, were utilized as a core material in sandwich composites.
The three type of mass density materials are recorded as 1, 2 and 3 respectively.
The aluminum foam materials of three layered different density are connected to form laminated composite structures.
