“…This work follows our previous research about the use of whole rice husk as plant aggregate to develop an insulating lightweight concrete like LHC for building envelopes [5]. The recovery of this crop residue without any burning or grinding to design such a material was almost unexplored.…”

“…However, it cannot be used as a load bearing material because of its compressive strength being only slightly over 0.30 MPa at early ages [5]. Since the mechanical strength of this kind of building material is very low, some authors especially focused on the improvement of LHC compressive strength.…”

<p>El cemento es una de las materias primas en la producción del concreto hidráulico, pero su producción es considerada como uno de los procesos más contaminantes en nuestro planeta. El proyecto de investigación analiza el comportamiento mecánico, físico y químico de una mezcla de concreto hidráulico modificado con sílice obtenida por la incineración de cascarilla de arroz. La metodología utilizada fue un diseño experimental que se trabajó con cemento Holcim M1 Concretera, se utilizó como muestra patrón un diseño de mezcla de concreto hidráulico para una resistencia a la compresión de 350 Kg/cm2, y resistencia a la flexión de 42 Kg/cm2. La modificación se realizó mediante la sustitución del cemento por ceniza de cascarilla de arroz (sílice), en proporciones del 5%, 15% y 30%. Los resultados muestran la viabilidad para el porcentaje de sustitución de 5% en la resistencia a la compresión, la tracción indirecta y a la flexión, por lo tanto, hay una viabilidad técnica para aplicar este procedimiento.</p>

Lightweight aggregate concrete is a material with very low density and good thermal insulation, and several types of lightweight aggregates have been used for lightweight concrete. Since the characteristics of lightweight aggregates strongly affect the properties of lightweight concrete, a proper consideration for the use of lightweight aggregate is very important for development of lightweight materials. In particular, the sizes and spatial distributions of lightweight aggregates can influence the material responses of lightweight concrete, such as compressive strength and thermal conductivity. In this study, different types of gradings of lightweight aggregates are adopted to investigate the effect of gradings on the material properties. Liaver R , an expanded glass granulate, is used as a lightweight aggregate for the specimens. Virtual models of the lightweight specimens with different gradings are numerically generated, and both mechanical and thermal properties are evaluated using experimental and numerical approaches for more detailed investigation. The obtained results can be utilized to suggest an optimal grading that satisfies both the mechanical and thermal properties of lightweight concrete specimen.
