Technology Research of Non-Burnt Brick and Application to Highway Engineering

The climate and natural conditions are comparatively arid and in the western area of China. Many highways, passing through the desert fringe or hinterland are endangered by the wind and tignum is scarce along the roads. The non-burnt brick, being made of aeolian sand, utilizing cementations material has many advantages such as high strength, corrosion-resistance, water-fast, frost resistance, and so on. This paper summarizes the results of the experimental investigation on the non-burnt brick, which demonstrates that the brick used in road kerb and slope protection can not only minimize the engineering cost, but also decrease the sand erosion. The practice shows that the brick being made of aeolian sand used in road has a good effect on engineering economy and road protection. This provides a new kind of protective material for road construction in desert areas.
