Cartilla dosificación mezclas de concreto. Agregados del punto de acopio Rodeb

Abstract

Concrete is a mixture composed of natural and artificial materials, which depends on the physical and chemical properties of elements such as cement, water and stone aggregates. The workability and strength of the concrete is given directly by the proportions obtained in the mix designs, which vary according to the physical properties of their aggregates. A suitable concrete mix design under any of the technical methodologies, ensures that the structural elements based on this material, reach the expected resistances under the load demand of the structure. Hence its importance in structural design.

According to the above, this document aims to socialize the community of Tocancipá, Walker's methodology for the design of concrete mixtures with compressive strengths of 21 and 28 MPa, using the aggregates of the collection point Rodeb in Sopó, Cundinamarca. This paper is a research product developed in the project: Physical-chemical, mechanical and mineralogical characterization of sandstones used for the construction of the free zone of Tocancipá, in the Rodeb and Acopios quarry - Sector Hato Grande - Sopó, led by Geologist Ph .D Javier Eduardo Becerra Becerra and with the participation as co-investigators of the engineers Ferney Oswaldo Peña (M.Sc) and Rubby Stella Pardo Pinzón (M.Sc).
