Abstract
ABSTRACT The optimisation of the UHPC granular skeleton shows resistance, durability and environmental gains. However, for the manufacture of UHPC, it is not feasible to sieve the aggregates in order to obtain an optimum curve of granular skeleton. An existing alternative is to mix the aggregates in order to obtain a curve close to the optimal curve. In this sense, the present research presents a methodology to perform mixtures of aggregates by means of matrix analysis combining the packaging models of Andreasen and Andersen modified and of Toufar while analysing the best packaging coefficient to be used with the objective to reduce cement consumption. The results indicate that matrix analysis can be used, leading to a low void rate in the granular mixture.
