1. Technological properties of a self-bloating clay and expanded-clay aggregate for the production of lightweight concrete
Abstract The global interest in an increasingly sustainable economy, with a reduction in the consumption of raw materials and energy, can be supported by the growth in the use of lightweight concrete (LC) produced with expanded-clay aggregates (EA). The main qualities of natural self-bloating clay for the production of EA were studied, analyzing the paramete

2. Application of Support Vector Machine and Finite Element Method to predict the mechanical properties of concrete
Abstract Compressive strength and Young’s modulus are the main properties used in the design of concrete structures. They are responsible for the cost, safety and dimensioning of the structure, and are generally measured in expensive and time-demanding tests. This fact encourages researches for fast and cost-effective methods to investigate the concrete’

3. Effects of pre-wetting aggregate on the properties of mortars made with recycled concrete and lightweight aggregates
RESUMO Este artigo buscou verificar a substituição parcial do agregado natural, areia (NA) por agregado de concreto reciclado (RCA) ou agregado leve (LWA) em argamassas, sob a hipótese que agregados pré-molhados produziriam melhoras nas propriedades da argamassa. Para isso, avaliou-se as propriedades das argamassas no estado fresco, como massa específic

4. Produção de agregado sintético de argila com reaproveitamento de resíduo de vidro
RESUMO É objetivo da construção civil, reduzir o peso das estruturas e consequentemente os custos com as fundações. A substituição de britas por agregados leves é a alternativa mais utilizada. No entanto, sobretudo no Brasil, só existe uma única fábrica de agregados leves localizada em São Paulo, sendo oportuna a pesquisa de matériasprimas para

5. Experimental Investigation on Self-Compacting Self-Curing Concrete Incorporated with the Light Weight Aggregates
ABSTRACT Self-Compacting Concrete (SCC) flows around obstructions by its self-weight to fill entirely and self-consolidate (without any need for vibration), without any part of disconnection and chunking. The eradication of the need for consolidation leads to better quality concrete and substantial improvement of running conditions. The fresh state of SCC mi

6. Calcined Clay Lightweight Ceramics Made with Wood Sawdust and Sodium Silicate
This paper aims to study the influence of including wood sawdust and sodium silicate in the production process of calcined clay lightweight ceramics. In the production process first, a sample used by a company that produces ceramic products in Brazil was collected. The sample was analysed by techniques of liquidity (LL) and plasticity (LP) limits, particle s

7. Ductility of reinforced lightweight concrete beams and columns
This paper presents analytical and experimental results on ductility of reinforced lightweight concrete beams and columns in the form of moment curvature relationships, and compares the response with that of normal reinforced concrete members. The experimental part is limited to flexural tests on beams made of lightweight concrete. The latter is obtained wit

8. 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
