13. The influence of the covering mortar in the axial compressive strength of masonry prisms composed of concret blocks of non load-bearing masonry / Influência da argamassa de revestimento na resistência à compressão em prismas de alvenaria resistente de blocos de concreto
In the Metropolitan Region of Recife some buildings had been constructed where the masonry fulfills function structural been, however, composed of blocks originally confectioned for non load-bearing masonry. This constructive system is regionally known as "coffin buildings". To take handle of the correct evaluation of the conditions of a building like these,

14. Structural panel project for social housing making use of small diameter round-wood: product development / Painéis estruturais utilizando madeira roliça de pequeno diâmetro para habitação social: desenvolvimento do produto
The purpose of this work is to identify, from the analysis of the production chain of forest based products, the chances of making use of small diameter round-wood of the Eucalyptus and Pinus types, for the production of sealing structural panels destined for social housing. Wood as a renewable building material and, in accordance with the environmental a

15. Evaluation of physical and mechanical properties of steam cured concrete made with high early strenght Portland cement and blastfurnace slag cement containing silica fume / Avaliação das propriedades fisicas e mecanicas de concretos produzidos com os cimentos Portland de alta resistencia inicial e de alto-forno aditivados com silica ativa curados termicamente
The durability of concrete structures depends on porous structure and its impermeability. The entrance of water and deleterious agents begin the damage processes and reduce the life of the concretestructure. ln that way, the aim of this work was to evaluate the mechanical resistance, permeability, absorption and natural carbonation of concretes submitted to

16. Uso e Aplicação do Poliestireno Expandido (EPS) Reciclado para Impermeabilização por Impregnação de Superfícies de Concreto Pré-fabricado
The performance and the surface appearance of concrete are both related to its porosity. A reduction in porosity, with a consequent reduction in permeability, could be an option for increasing the durability of the concrete and preserving its surface characteristics. Esthetically, deterioration of the concrete surface causes an imbalance in the utility x app

17. ESTUDO DA PERMEABILIDADE À ÁGUA NA CAMADA DE COBRIMENTO DE PROTÓTIPOS DE CONCRETOS COM ALTOS TEORES DE CINZA VOLANTE
The civil construction industry is, as times goes by, more related with echo-social efficiency and society and the concrete, most used building material, has its use associated with concerns on the durability and the performance of the constructions, looking for the optimization of the natural resources. The durability esteem of a concrete is the function of

18. Behavior of conventional glass fibers in matrix of Portland cement modified with latex and with the addition of silica fume. / Comportamento das fibras de vidro convencionais em matriz de cimento Portland modificada com látex e adição de sílica ativa.
Portland cement mortar and concrete are durable building materials, relatively cheap and, despite they display a good rigidity and an adequate compressive strength, they have other deficient properties such as tensile strength, impact, fatigue, beyond low toughness and ductility. A considerable improvement of these properties can be obtained adding fibers, i
