Análise experimental comparativa entre concretos de pós reativos dosados pelos modelos de Alfred e Andreasen

Abstract

Concrete is one of the most widely used materials in the construction industry worldwide. Over the years, studies and research are conducted in order to improve their physical and mechanical properties. The concrete reactive powders (CRP) is the last ultraresistant material based on Portland cement developed, reaching compressive strength up to 800 MPa. This research aimed to develop concrete reactive powders (CRP) and use some dosage models based on the method of particle packing and compare these with the purpose of measuring its resistance to compression. For this, we used the models of Alfred and Andreasen, with three lines for each model and disruption of the samples in 1,3 and 28 days. The tests resulted in compressive strengths similar between models of dosage.
