Resumen
El módulo de Young de los adhesivos cementosos en sistemas de calefacción radiante ligeros (LRHS) cambia con la temperatura. El módulo del adhesivo C2S1 varió de 4600-5800 MPa, mientras que el C2S2 se mantuvo constante en 2300 MPa entre 30 °C y 50 °C.
Área de la Ciencia:
- Ciencia de Materiales
- Ingeniería Civil
- Materiales de Construcción
Sus antecedentes:
- Los sistemas de calefacción radiante ligeros (LRHS) sin soleras dependen de adhesivos para unir las capas.
- Los cambios en el módulo de Young del adhesivo bajo estrés térmico pueden comprometer la integridad del piso y causar deslaminación.
- La comprensión del comportamiento del adhesivo es crucial para la durabilidad de los LRHS y otras particiones de edificios.
Objetivo del estudio:
- Investigar la variación del módulo de Young (E) en adhesivos cementosos deformables (C2S1 y C2S2) bajo acciones térmicas.
- Determinar el impacto de las fluctuaciones de temperatura en el rendimiento del adhesivo en aplicaciones LRHS.
- Proporcionar datos para analizar la durabilidad y el rendimiento de los componentes de construcción sometidos a cambios de temperatura.
Principales métodos:
- Se probaron muestras de adhesivos cementosos C2S1 y C2S2 en una cámara térmica de 30 °C a 50 °C.
- Se realizaron pruebas de resistencia a la compresión y mediciones de deformación utilizando la técnica del extensómetro.
- Se aplicó análisis matemático, incluyendo regresión polinomial y las fórmulas de la "parábola de Madrid", a los resultados.
Principales resultados:
- El módulo de Young (E) para el adhesivo C2S1 varió entre 4600 MPa y 5800 MPa en el rango de temperatura probado (30 °C - 50 °C).
- El módulo de Young (E) para el adhesivo C2S2 se mantuvo constante en 2300 MPa dentro del mismo rango de temperatura.
- La temperatura influye significativamente en las propiedades mecánicas de los adhesivos cementosos deformables utilizados en LRHS.
Conclusiones:
- El estudio cuantifica el módulo de Young dependiente de la temperatura de los adhesivos C2S1 y C2S2 para aplicaciones LRHS.
- Estos datos son esenciales para predecir el rendimiento a largo plazo y garantizar la integridad estructural de los pisos con calefacción y otros elementos de construcción.
- Los hallazgos respaldan un diseño y análisis numérico mejorados para particiones de edificios expuestos a variaciones térmicas.

01:16Dynamic Modulus of Elasticity of Concrete
907
The dynamic modulus of elasticity assesses how a concrete structure deforms under impact or dynamic loads. It is typically higher than the static modulus of elasticity, measured under slow, steady loading conditions.
The sonic test is a common method to determine the dynamic modulus. In this test, a concrete beam, sized either 6 x 6 x 30 inches or 4 x 4 x 20 inches, is clamped at its center. Vibrations are initiated at one end of the beam by an electromagnetic exciter unit powered by a...

01:15Relation between Poisson's ratio, Modulus of Elasticity and Modulus of Rigidity
523
Deformation occurs in axial and transverse directions when an axial load is applied to a slender bar. This deformation impacts the cubic element within the bar, transforming it into either a rectangular parallelepiped or a rhombus, contingent on its orientation. This transformation process induces shearing strain. Axial loading elicits both shearing and normal strains. Applying an axial load instigates equal normal and shearing stresses on elements oriented at a 45° angle to the load axis.

01:15Strain and Elastic Modulus
8.8K
The quantity that describes the deformation of a body under stress is known as strain. Strain is given as a fractional change in either length, volume, or geometry under tensile, volume (also known as bulk), or shear stress, respectively, and is a dimensionless quantity. The strain experienced by a body under tensile or compressive stress is called tensile or compressive strain, respectively. In contrast, the strain experienced under bulk stress and shear stress is known as volume and shear...

01:09Thermal Stress
3.2K
If the temperature of an object is changed while it is prevented from expanding or contracting, the object is subjected to stress. The stress is compressive if the object expands in the absence of constraint and tensile if it contracts. This stress resulting from temperature change is known as thermal stress. It can be quite large and can cause damage. To avoid this stress, engineers may design components so they can expand and contract freely. For instance, on highways, gaps are deliberately...

01:20Elasticity in Concrete
300
Upon subjecting concrete to moderate or high uniaxial compressive or tensile stresses, the strain response is non-linear relative to the stress applied. As the stress is removed, the resulting stress-strain curve deviates from the original path traced during loading, creating a hysteresis loop, indicative of the concrete's non-linear and non-elastic properties. Typically, a material's modulus of elasticity, which is a measure of the material's stiffness, is inferred from the linear...

01:20Strength of Cement
428
Strength tests for cement are not performed directly on neat cement paste due to difficulty in obtaining consistent, reliable specimens. Instead, cement is typically tested in the form of cement-sand mortar.
For compressive strength tests, ASTM C 109-05 standards prescribe a cement-sand mix ratio of 1:2.75 and a water/cement ratio of 0.485 for making 2-inch cubes. These cubes are mixed, cast, and cured in saturated lime water at 23°C until testing. Flexural strength testing, outlined in...
