2. Argamassas eco-eficientes com incorporação simultânea de material de mudança de fase e cinzas volantes
RESUMO Atualmente, a indústria da construção é um dos principais setores europeus responsáveis pelos elevados níveis de consumo de energia, extração de matérias-primas e produção de resíduos. Cada vez mais o consumo de energia proveniente de fontes renováveis e a reutilização de resíduos industriais constituem a única maneira de minimizar es

3. Properties of concrete manufactured with use of ceramic sanitary ware waste as aggregate
RESUMO Na fabricação do concreto, cimento (o Portland é o mais usado), água e agregados (classificados em finos e grossos), são usados. Com a utilização de inúmeras matérias-primas, a geração de resíduos é inevitável, seja na construção civil ou em outros setores, como as indústrias produtoras de materiais cerâmicos. Entre os tipos de resí

4. Novel Artificial Ornamental Stone Developed with Quarry Waste in Epoxy Composite
Ornamental stones, such as marble and granite, are worldwide used as pavement cover and lining parts in civil construction. Dwindling deposits and environmental pollution, due to extraction methods, have motivated the replacement of natural ornamental stones by synthetic ones. In particular, artificial ornamental stones are being developed with mineral waste

5. Cement plate slab production with the incorporation of glass wool waste ground
Abstract One of the characteristics of Civil Construction is its ability to absorb a wide range of wastes to produce new products. Therefore, the objective of this study was to evaluate the behavior of cement plates produced with the addition of ground glass wool waste and in natura, in shredded form. The tensile strength tests in bending and permeability we

6. Impact of an Alkaline Solution on the Chemistry, Mineralogy, and Sorption Properties of a Typic Rhodudult Soil
Abstract The preferred option for disposal of short-lived low and intermediate level radioactive wastes is a near surface disposal facility in which soil is one of the barriers that avoid radionuclide migration outside the controlled area. For construction of that kind of facility, concrete is widely used, and its interaction with water induces its degradati

7. Industrial Wastes as Alternative Mineral Addition in Portland Cement and as Aggregate in Coating Mortars
This paper presents an evaluation study of wastes from pulp and paper as well as construction and demolition industries for application in cement-based materials. The alternative raw materials were used as a source of calcium carbonate (CaCO3) and as pozzolanic material (water-reactive SiO2) in partial replacement of Portland cement. In addition to the hydra

8. Mechanical Behavior of Concrete Modified by Replacement of Cement by Rice Husk Ash
ABSTRACT Construction industry is in need of lump sum quantities of materials which has increased both their demand and price. The use of large quantities of cement leads to increasing CO2 emission and as a consequence, the greenhouse effect. Consumption of wastes and byproducts from various sources in the manufacture of concrete has gained a great deal of i

9. Development of Epoxy Matrix Artificial Stone Incorporated with Sintering Residue from Steelmaking Industry
The present work is part of an innovation research project aiming to develop artificial stone from industrial wastes. In principle, the project goal is to fabricate artificial stones with improved characteristics to be used as plates for housing and road construction. In this work, the specific industrial residue was an electrostatically precipitated powder

10. Treatments of non-wood plant fibres used as reinforcement in composite materials
This paper presents a summary of the knowledge on fibres and pulps of non wood tropical plants used as reinforcement in cementitious composites accumulated during the recent years by Guadeloupean and Brazilian teams participating in collaborative work. Vegetable fibres represent a good alternative as non-conventional materials for the construction of ecologi

11. Taxa de geração de resíduos da construção civil em edificações na cidade de João Pessoa / GENERATION RATE OF CONSTRUCTION WASTE IN BUILDINGS IN THE CITY OF JOÃO PESSOA.
Given the high index of construction in the city of João Pessoa, in northeast Brazil and the frequent irregular disposal of its residues, the objective of this work was to study the generation rate of construction wastes (CW) based on constructed area of the building, so that a more effective inspection can be implemented by the proper instances. A sample o

12. Performance estimation for concretes made with recycled aggregates of construction and demolition waste of some Brazilian cities
The aim of this paper is to verify the influence of composition variability of recycled aggregates (RA) of construction and demolition wastes (CDW) on the performance of concretes. Performance was evaluated building mathematical models for compressive strength, modulus of elasticity and drying shrinkage. To obtain such models, an experimental program compris
