This article is a research in order to determine the proportions of the design of structural concrete mix with higher strength than plain concrete, which was used to obtain this concrete from pumice mineral pumice powder of Damavand mine, which was deposited in this mine as mineral tailings, and compared with concrete containing micro-silica powder. has been According to the approach of environmental protection and sustainable value production of Betonyar Concrete Company, it was decided to prepare and examine this type of mine tailings and examine its uses in concrete.

Considering the practical aspects of this type of concrete, the variables in different plans are: the ratio of water to cement materials, the amount of pumice powder and micro-silica. The compressive strength tests of the samples made in the concrete laboratory of the company were placed in the processing pond until the day of the test. The results of this research show that it is possible to achieve a compressive strength close to that of concrete containing micro-silica powder by using mineral pumice powder with a lower content than micro-silica.
