Course Completion Work (TCC) linked to the SICon research group is defended at UFV
The undergraduates Franciele Ferreira Pereira, Lívia de Freitas Gomides Meriguis and Maíra Carrara Roque, from the Civil Engineering course at the Federal University of Viçosa, defended their Course Completion Work, under the guidance of Professor Dr. José Maria F. de Carvalho, and being co-oriented by Eng. Me. Gustavo José R. Lopes – both members of SICon – on 05/24/2021 at 10am.
The title of the work was: Proposals for the Use of Glass Sand and Bottom Ash in the Production of Eco-efficient Precast Elements at the UFV Precast Concrete Plant.
Summary of the theme: Precast concrete elements are widely used in the construction industry, and due to environmental impacts related to cement and aggregate production, the theme of sustainability has gained space in the market. Thus, the theme proposes to establish methodologies to improve the eco-efficiency of the products of the concrete precast plant of the Federal University of Viçosa (UFV) while promoting adequate disposal to the waste generated on the Campus, being suggested in this work adjustments of layout and dosages of eco-efficient concrete for the plant, using traditional and sustainable aggregates obtained from the recycling of glass and bottom ash.

The Civil Engineering Bachelor ‘s student Matheus do Nascimento Duarte, from the Federal University of Viçosa, defended his Course Completion Work (TCC), under the supervision of Professor Dr. José Maria F. de Carvalho, on May 19, 2021, at 9am.
The title of the study was: Evaluation of experimental dosage method of no-slump concrete.
Theme Summary: No-slump concrete is a type of concrete used in the manufacture of precast elements. Because it is a low-water concrete mixture, it has the ability to maintain its form after compaction in the fresh state. The present work proposed an experimental dosage method of no-slump concrete using the Modified Andreasen method, with optimum moisture content. To evaluate the method, concretes were produced with three cement contents and three compaction energies. The optimum moisture content was determined using a sand rammer. The materials were evaluated determining their packing densities in the fresh state, and mechanical strength, porosities and ultrasonic pulse velocities in the hardened state. The concretes showed high packing densities and promising results of mechanical strength, highlighting the influence of the cement content and compaction energy.
