چکیده:

Growing process of construction types in the current age in many countries, especially Iran, comes with consumption of building materials increase and after it, the destruction of the envi-ronment. On the head of construction materials, there is the most consumed material namely concrete. Approximately per person in the world, annual, One ton of concrete (consisting of sand, water, seed materials and cement) are produced and producing of Portland cement-manufacturer part of concrete-in addition to consuming fossil fuels and coal leads to production of unwanted greenhouse gases and fine-grain materials. On the other hand with the increasing of people needs the amount of agricultural waste is added constantly, while one of the industries that provides the efficiency possibility of these wastage is the construction industry. Thus we want to use a natural material for replacement of cement, such as Rice husk ash, with the aim of reducing fuel consumption in the production of concrete and also its more durability to the non-rebuilding, move toward advancing sustainable materials production and survival of the envi-ronment. Hence, with using comparative-analysis method, we study the effects of this valuable material in the concrete. Thus the results show that using Rice husk ash in concrete, addition to improving mechanical properties of concrete could act to reduce fuel consumption and co amount in the production of concrete. Also with using in the Northern indigenous construction of Iran and other rice producer countries help environment health with regard to sustainable trans-portation.
