1. Stabilized mortar with air incorporator agent and plasticizer set retarder: performance measurement
Resumo Este estudo tem como objetivo desenvolver três argamassas estabilizadas para alvenaria com aditivo incorporador de ar e plastificante retardador de pega para comparar com uma argamassa convencional com cal. Foi analisado o índice de consistência, a massa específica, o teor de ar incorporado, a retenção da água, o tempo de pega através do calor

2. Resistência e deformabilidade de blocos vazados de concreto, prismas e paredes e suas correlações com as propriedades mecânicas dos materiais constituintes / Strength and deformability of hollow concrete blocks, prisms and walls and their correlation to mechanical properties of constituent materials
This work aims to identify and correlate the mechanical properties of concrete and bedding mortar to the structural behavior of hollow concrete blocks, prisms and walls, by mean of physical and numerical modeling. A detailed experimental investigation was carried out by assuming as a premise the use of plastic consistency concrete to produce hollow blocks an

3. Sobre o emprego de tijolos e blocos de vedação com função estrutural em edificações de pequeno porte.
The small and medium size, ground or one floor constructions in the inner São Paulo state, specially the residential ones, are predominantly build with massive ceramic brick or structural function closure blocks without structural concrete (beam or columns). This is known as resistant masonry. This building way is not standardized in Brazil. It shows one si

4. A influÃncia das caracterÃsticas do revestimento na resistÃncia à compressÃo de paredinhas de alvenaria de blocos cerÃmicos de vedaÃÃo
As edificaÃÃes habitacionais em alvenaria resistente de atà quatro pavimentos, conhecidas como âprÃdios caixÃoâ, nÃo atendem aos requisitos de estabilidade quando analisadas pelas formulaÃÃes de cÃlculo aplicadas Ãs alvenarias estruturais. A consideraÃÃo do revestimento e dos contraventamentos das paredes entre si, explicam a estabilidade dessa

5. ConsideraÃÃes sobre soluÃÃes para recuperaÃÃo de prÃdios construÃdos com alvenaria resistente / Considerations about solutions for recovery of building constructed with resistant masonry
The creation of the Banco Nacional de HabitaÃÃo (BNH) and the necessity to supply the Brazilian habitation deficit mainly for the band of the population with minor purchasing power, directed the market of the civil construction to search for new constructive systems as alternative to the products and traditional processes. The resistant masonry with hollow

6. Analysis of the structural behavior of a group of buildings built with resistant masonry submitted to the action of settlements / AnÃlise do comportamento estrutural de um conjunto de edifÃcios construÃdos com alvenaria resistente submetidos à aÃÃo de recalques
In the Metropolitan Area of Recife, there are about six thousand buildings with up to four storeys, made from resistant masonry. Approximately ten buildings of this type collapsed and serious pathological manifestations were verified in tens of others. In some of them there were fatal victims, as in the cases of Ãricka and Part B of Enseada of Serrambi buil

7. InfluÃncia da argamassa de revestimento na resistÃncia à compreensÃo axial em prismas de alvenaria resistente de blocos cerÃmicos
Since the 70s, buildings called âcaixÃesâ began to be built in a large scale, made of resistant masonry with up to four floors, in the Metropolitan Area of Recife. Itâs known that these constructions were built without technological basis and necessary technical rules, national and international ones. Itâs noticed that these constructions and the materi

9. Rehabilitation of masonty walls by the application of resistant ferrocement overlays. / Reabilitação de paredes de alvenaria pela aplicação de revestimentos resistentes de argamassa armada.
O presente trabalho apresenta os resultados obtidos na pesquisa sobre o uso de revestimentos resistentes de argamassas de cimento e areia na reabilitação de paredes de alvenaria, quando solicitadas à compressão axial, compressão diagonal e flexão de painéis. Os ensaios foram baseados nas normas NBR 8949, ASTM 519 e NBR 14322 respectivamente. O objetiv
