A Mix Design Methodology to Produce high Strengh Concrete with Local Materials in Bolivia Study Case: La Paz

At present, there is not a definitive mixing method that can be said to be exclusive for high strength concretes, indeed, many researchers have achieved these concretes without using defined reference curves, but only using simple relations between the amount of coarse and fine aggregate allowed the respective mixture proportion. This article presents an empirical methodology for designing mixtures for high strength concrete, making use of materials available in La Paz, Bolivia. This methodology presents a theoretical basis on the microstructure of concrete and the appropriate use of local materials that are used in the construction of civil works and can be applied to the construction site in reinforced concrete constructions, taking care that the materials, comply with the recommendations made in this article.
