Unburned bricks are becoming more popular in Vietnam because they are mainly stone, sand, and cement, saving energy and not contaminating the environment with smoke and dust. The majority of the stone used in the material comes from the construction stone mining process. Meanwhile, because the amount of shaved ice produced by the mining process in Quan g Ninh is relatively large compared to that of the relatively small, research into the possibility of using quarry land as a source of raw materials for unburnt production will help with the solid treatment of fossil fuels. The mining procedure and mode vary to use the resource field and protect the environment. This is the outcome of Quang Ninh University of Industry’s contract f or the interference of Profession number 43g / HD-KHCN dated 12/06/2021
