Modeling Concrete Tensile Strength from Fly Ash and Alccofine as Partial Replacement for Cement

Abstract

Tensile strength development were carried applying derived modeling and simulation, this study is to monitor the behaviour of the material in tensile state, Several materials has been used as modifiers or partial replacement, but the application of alccofine as a micro-fine materials has not been thoroughly applied by experts, this product has fine particles that is more finer than cement including other materials, the tensile strength behaviour from the studies carried out is application of numerical simulation, rapid increase was experienced based on the material, this depend on mixed design that determine the developed performance on both fresh and harden state of concrete, these are observed from the concrete effective particle distribution structure. Similar condition was observed on fly ash because its quality as a by- product applied frequently as pozzolan to produce hydraulic cement, it is a partial replacement for Portland cement in production of concrete. It improve the strength of concrete partially replace with alccofine and fly ash, the behaviour of both materials were expressed from these figures, the trend linearly experienced rapid growth to the optimum curing age. The study of combining these two materials expressed the required tensile that is of high performance on concrete structure based on the mixed designed, the derived predictive material were compared with validated values and both parameter expressed best fit correlation. The study is imperative because the application of alccofine and fly ash has to a large extend generates the required tensile strength from partial replacement for cement, the developed strength has shows it economical values based on the tensile strength generated from the study.
