“…7. It was seen that the results found were in the same order of magnitude, in accordance with the small variations in density in the hardened state recorded for the mortars [32]. Although the results of dynamic modulus of elasticity were similar, higher values were observed for SLMs developed with sands M and F. In most cases, lower values were verified in SLMs with sand V. This was consistent with the lower compressive strengths at 28 days showed by these mortars.…”

The properties of self-leveling mortars (SLMs) in the fresh and hardened state are strongly affected by their formulation. In this study, the influence of three different quartz sands (different physical characteristics) was investigated in SLMs, as well as the replacement of these sands by crushed basalt filler. The tests performed were: spreading, density in the hardened state, absorption by immersion, flexural strength, compressive strength, dynamic modulus of elasticity, water capillary absorption, and drying shrinkage. The results obtained show that the particle size distribution (PSD) of sand influenced most of the properties. The shape and texture of the sand grains did not seem to have much influence on the properties of SLMs when the PSD was different. The powdery (fine) material content of sand seemed to affect most notably properties in the fresh state and shrinkage. The increase in the content of sand replacement by filler decreased the workability of SLMs, however, it may improve the initial flexural and compressive strengths and reduce the drying shrinkage.

“…A ocorrência do estágio II está relacionada ao comportamento de argamassas de fácil aplicação e espalhamento [15]. A curva do teor de 80% também apresentou dificuldade de escoamento, logo atingindo o enrijecimento por deformação, ou seja, pouca trabalhabilidade e enrijecimento brusco, sendo impossível a sua aplicação [16]. Já a curva do teor de 100%, foi a única a passar de forma clara pelos três estágios, deformação elástica, deformação plástica e enrijecimento por deformação [17].…”

Resumo A construção civil é um dos maiores consumidores de recursos naturais. Por isso, vem sendo estudado a adição de materiais alternativos para a produção de argamassas, como a incorporação de resíduo da produção de granito na substituição parcial ou total do agregado. Este trabalho tem como objetivo analisar a viabilização do granito em argamassa e realizar o ensaio de reologia a fim de analisar a viscosidade e o escoamento da argamassa. Para isso foi estabelecido à incorporação de granito em 0%, 20%, 40%, 60%, 80% e 100%. Assim, no estado fresco, foram realizados ensaios de índice de consistência, conforme NBR 13276/2005 e ensaio de análise reológica através do squeeze-flow, consoante NBR 15839/2010. O squeeze-flow é um método que avalia o comportamento da argamassa em relação à carga aplicada e a deformação ocasionada. Os resultados mostram que as argamassas com teores de 0% e 20% apresentaram dificuldade de escoamento, enquanto o teor de 80% foi necessário uma redução de carga para a deformação elástica. Já a amostra de 100% apresentou deformação por enrijecimento e os teores de 40% e 60% apresentaram maior deformação plástica e melhor desempenho, concluindo-se, então,a viabilizaçãoda utilização de granito em argamassas.

“…An example is the waste resulting from the gravel production process in quarries installed on rock, called quarry fines (16). High contents of crushing filer are often formed, around 10 to 20%, during the comminution of the small crushing aggregate (17). This material is sometimes used in paving works in the composition of bases, sub-bases and asphalt concrete, and its application is on a small scale.…”

The production of adhesive mortar uses large proportions of sand, causing undesirable environmental impact as this is a finite resource. In recent years, the insertion of civil construction waste in cement matrixes has intensified with the objective of replacing sand in the mortar manufacturing process. Therefore, in this study, the proportions of 5%, 10%, 15% substitution of the mineral aggregate by basalt dust waste in the production of industrialized adhesive mortar were adopted. The reference mixture of 1:3 (cement: sand) was adopted and the water/dry material ratio was set at 0.20. The adhesive mortars produced in the tests to determine the consistency index, water retention, mass density, open time, tensile strength and water absorption by capillarity were analyzed. The results were satisfactory, demonstrating that it is feasible to use the waste as a substitute for sand in the production of industrialized adhesive mortars.
