1. Characterization of Fiber Reinforced Self-Consolidating Mortars for Use in Patching Damaged Concrete
Abstract This research aims to study the effect of supplementary cementitious materials (SCMs) such as quarry dust limestone (QDL) and natural pozzolana (NP) on the performance of fiber reinforced self-consolidating repair mortars (FR-SCRMs). Based on previous optimization of QDL and NP replacement ratios, two mortar mixtures incorporating 10% QDL and 20% NP

2. Using fine recycled concrete aggregate for mortar production
This research assessed the performance of mortars in which recycled concrete aggregates (RCA) was a component. It replaced natural sand but kept the same particle size distribution. Three mortars were produced with replacement ratios of 20%, 50% and 100% as well as a reference mortar containing no recycled aggregate. The compressive and flexural strength, wa

3. Synthesis and characterization of methylcellulose from cellulose extracted from mango seeds for use as a mortar additive
Methylcellulose was produced from the fibers of Mangifera indica L. Ubá mango seeds. MCD and MCI methylcellulose samples were made by heterogeneous methylation, using dimethyl sulfate and iodomethane as alkylating agents, respectively. The materials produced were characterized for their thermal properties (DSC and TGA), crystallinity (XRD) and Degree of Sub

4. Análise comparativa da aderência de tipos rochosos assentados com três argamassas / Comparative analysis of adherence of stone types seated with three mortars
O presente estudo trata da determinação da resistência de aderência de três rochas: arenito, mármore e quartzito assentados com três diferentes argamassas (industrializada, resíduo e para porcelanato). Os ensaios de resistência de aderência à tração foram executados tanto na face lisa como na não polida (natural) dos corpos de prova e seguiram

5. Setting of dimension stones: study of the tack with adhesive mortar / Fixação de placas de rochas ornamentais: estudo da aderência com argamassa colante
In coverings of walls the setting of dimension stones can be made with metallic inserts or by tack with mortar. In the nestings with mortar the values of tack, for norm, must be superior the 1 MPa and the maximum height of covering cannot exceed 3 m. In the present work, assays with floor tiles of three types of "granites" had been made to compare the tack o

6. Avaliação de sistemas de reparo para o problema de abrasão do concreto de superfícies úmidas em UHEs
The research field of construction pathology has been steadily growing lately due to natural degradation observed in different structures. In this sense, great attention has been devoted to special concrete structures such as hydroelectric power plants (HPP) because of their complexity and importance, socially as well as economically. One of the pathologies

7. Avaliação experimental dos metodos de prevenção de fissuras na interface alvenaria de vedação e pilar de concreto / Experimental analysis of methods of prevention of splitting in the fair-faced masonry and concrete column
The splitting of the fair-faced masonry-structure are very usual but it is not wellknown the reason of its occurrence, although they are frequent, specially the ones that appear in the linking of the masonry-concrete column. The purpouse of this work was to study the best anchorage technique between masonrystructure, being evaluated its efficiency to prevent

8. Estudo da influência das adições de sílica ativa e copolímero estireno acrílico nas propriedades de argamassas para assentamento de porcelanato / Study of the copolymer styrene acrylic and silica fume adittions influence in the properties of mortars to fix porcelain stoneware tiles
Apesar de suas excelentes características técnicas e estéticas, a aplicação de porcelanato em fachadas requer especial atenção devido ser um material diferente das cerâmicas convencionais, além de que as fachadas estão sujeitas a diversos agentes capazes de danificar os revestimentos cerâmicos. O baixo índice de absorção de água do porcelanato

9. Rejuntamento de revestimentos cerâmicos: influência das juntas de assentamento na estabilidade de painéis. / Grouting of ceramic tiles: influence of joints in stress relief.
This study presents a bibliographical revision regarding the ceramic tile grouts. Here, the international nomenclature is explored and the types of grouts as well as its employments are enumerated. To base the reader on the ceramic tile cladding, its main concepts are shown succinctly. Being the grout an important component of the ceramic tile cladding, its

10. Critical analysis of the requirements and criteria for cementitious adhesives quality. / Análise crítica dos requisitos e critérios de qualidade da argamassa colante.
Os métodos de ensaio editados pela ABNT para caracterizar argamassas colantes foram um avanço em termos de normalização do produto e ajudaram a melhorar sua qualidade. Entretanto, os métodos apresentam dispersão expressivamente elevada e especificam condições de ensaios que não condizem com a realidade das condições de campo. Em vista dessas discr
