1. Concreto ultraleve® estrutural com pérolas de EPS: caracterização do material e estudo de sua aplicação em lajes / Structural ultra lightweight concrete with EPS beads: material characterization and study of its use in slabs
The use of lightweight concrete is mainly due to the benefits provided by reducing the density of the material such as smaller efforts on structures, economy of molds and scaffolding, as well as lower costs of transportation and erection of precast constructions. Currently, besides the technical and economic issues, the choice of building materials should ta

2. Influence of surface roughness and the use of new types of fiber in bearing pads of cement-based material for precast concrete connections / Influência da rugosidade superficial e o uso de novos tipos de fibras em almofadas de argamassa para ligações de concreto pré-moldado
This paper presents the study of a mortar modified to be used as a bearing pad connections between precast concrete elements. This mortar is composed of cement and sand, with the addition of styrene-butadiene latex (SB), lightweight aggregate (vermiculite) and short fibers (polypropylene, glass and PVA). Previous research showed that this composite presents

3. High performance latex-modified lightweight aggregate concrete for thin precast components - dosage, production, properties and microstructure / "Concreto leve de alto desempenho modificado com SB para pré-fabricados esbeltos - dosagem, produção, propriedades e microestrutura"
This dissertation deals with the application of the high performance lightweight aggregate concrete (HPLWAC) for the production of thin precast components, such as structural and insulation panels and elements for covering. A concrete with special properties was presented, once the use of styrene-butadiene latex (SBR), silica fume, accelerating superplastifi

4. Precast concrete elements in structural masonry buildings. / Utilização de pré-moldados em edifícios de alvenaria estrutural
Precast concrete elements are a good option to improving the rationalization in structural masonry building process. They are related to the following features of this process: reduction of building times consumption, strict quality control, modular coordination and high level of manufacturing organization. This work deals with precast concrete elements comm
