Concrete is one of the common materials in hydraulic structures. On the other hand, due to growing environmental concerns and the need to conserve energy and resources, efforts have been made to use agricultural by-products as a supplementary cementing material. The application of agricultural wastes such as rice husk ash in concrete has been reported for many years. One of the agricultural wastes is pine cones. A large amount of pine cones around the pine trees are available each year. In most cases they are burned which may possess adverse environmental impacts. In this study, Pine Cone Ash (PCA) was prepared after 4 hours burning at a temperature between 550 to 600°C in a furnace. Cements in concrete samples were partly replaced by PCA in levels of 10, 20 and 30 % (mass). One of the important qualitative factors of concrete is its resistance against bad weather conditions and destructive alkaline and acidic environments. Substitution of waste materials will conserve diminishing resources, and will avoid the environmental and ecological damages caused by quarrying and exploitation of the raw materials for making cement. To some extent, it will help to solve the problem otherwise encountered in disposing of the wastes. Partial replacement of clinker or portland cement by slag, fly ash, silica fume, pozzolans and natural rock minerals illustrates these aspects. These sort of materials require little or no processing expenses. In recent years, nanotechnology has improved the characteristics of different materials. The single factor in emerging nanotechnology is high of nano materials area to volume. Increased area to volume ratio result in higher effect of atoms located in surface of particles than those within volume. This feature, increases nano particles reactions more intensely. In this research, the use of pine cone ash (PCA) and its nano particles, as cementation material, have investigated. Also the mechanical properties such as compressive strength, tensile strength and durability in water and in water containing magnesium sulfate have been measured. The cement were replaced with PCA and NPCA containing about 5% of nono paticles (NPCA) in levels of 10, 20 and 30 percent of weighted mass. Optimum percent of was 20%. The highest compressive strength, tensile strength and durability against magnesium sulfate are obtained in this percent. At the age of 180 days, samples contained 20% PCA and NPCA increased their compressive strength about 118.8 and 139.51 percent, respectively. At the age of 180 days, sample contained 20% PCA and NPCA increased their tensile strength about 142.1 and 127.18 percent, respectively. At the age of 180 days sample with 20% PCA and NPCA increased compressive strength 127.8 and 162.37 percent, respectively in magnesium sulfate medium. The weight loss of control samples in magnesium sulfate were 1.35 times more than samples contained 20% PCA and NPCA. Destruction of surface of NPCA samples in magnesium sulfate were less than the control samples. In respect to obtained results from present research, pine cone ash and its nano particles can be considered as an appropriate method to effective exclusion of this agriculture additive in concrete industry. In general, pine cone ash showed potentially as an appropriate method to utilize in concrete industry.
