Abstract Concrete mix design is the methodology for mixing binder, aggregate and water to achieve required physical, mechanical, thermal properties. In particular, physical properties depend on volume fraction of each element in concrete recipe. this study we considered cement mortar, complying with ASTM C105, as reference binder silica sand aggregate. The mortar was denser high conductivity co...
Cementitious matrices are the fragile materials that possess a low tensile strength. The addition of fibers randomly distributed in these matrices improves their resistance to cracking, substantially. However, the incorporation of fibers into a plain concrete disrupts the granular skeleton and quickly causes problems of mixing as a result of the loss of mixture workability that will be translat...
Bituminous mix design is a delicate balancing act between the proportions of aggregate sizes and bitumen content. For a given aggregate gradation, the optimum bitumen content is estimated by satisfying a number of mix design parameters recommended in the specifications. In this paper, some of new considerations related to the bituminous mix design are discussed. Bituminous mix design, with thes...
with many years of construction and application of common concrete, researchers have always been searching for a better composition. one of the notable ideas for achieving such a composition is using recycled materials. one of the materials which is suitable for environment and constant development is damaged tires .for studying mechanical properties of concrete containing tire particles, a ser...
