Investigation of the effective of distributed calcinate born minerals on concrete roads

In this study, both commercial colemanite and calcined colemanite minerals were added to the concrete and the changes in the mechanical and physical properties of the concrete were investigated in order to increase the use of boron mineral of our country which is very rich in boron mineral. As a result of this research, it is aimed to use boron mine on concrete roads. In the first part, the properties of concrete road, use percentages in the world and Turkey, the main components used in concrete, boron, commercial boron minerals, boron reserves in Turkey, it mentioned the company used beds and areas and previously conducted some studies are summarized . In the second part, Colemanite mineral was calculated as 1.25%,% 2.5,% 5,% 7.5,% 10,% 12.5 and% 15 according to cement weight. but no desired results were obtained. For this reason, a concrete mixture calculation of dmax 24 mm was made and colemanite mineral was added to the concrete in the same ratios. The addition of colemanite to the concrete having dmax of 24 mm gave positive results in terms of the concrete properties of concrete. Following these results, colemanite mineral was subjected to calcination process and the amount of B2O3 in it was increased and it was aimed to increase the positive effect on the concrete to higher levels. While investigating the effect of commercial colemanite and calcined colemanite mineral on concrete, concrete compressive strength, ultrasound transition speed, Schmidt test hammer were taken and experiments were made on physical properties of concrete. In the third chapter, the results obtained to evaluate the physical properties of concrete were given as graphs and the graphs were interpreted. In the fourth chapter, the results and recommendations from this study are given.
