The moisture content, temperature, type of aggregate, type of cementitious material and density of concrete are influential factors on the thermal conductivity. The aim of this paper is to review the techniques most commonly used to measure the thermal conductivity of concrete as well as to ...
In this work, measurements of the thermal properties of moist autoclaved aerated concrete specimens have been performed using both the heat flow meter apparatus (HFM) and the transient plane source te关键词: Autoclaved aerated concrete Moisture Thermal conductivity Heat flow meter apparatus Hot Disk DO...
From the this study, we can recommend the proper mix proportions for thermal insulation Panel or concrete. Expecially. the thermal conductivity of concrete composites made by polyurethane resin is almost the same as that of the conventional expanded polystyrene resin. 展开 ...
It was noticed that even at small amounts (up to 5%), mPCM (encapsulated in organic or inorganic shells) decreased the thermal conductivity of concrete by up to 37% [28]. Apart from the low thermal conductivity of mPCM, the reduction could also be related to both the low density and ...
Explore how the MTPS and TPS sensor can help you measure the thermal conductivity of cement and concrete in order to improve insulation.
Thus, in order to determine the best homogenization scheme predicting the effective thermal conductivity of foam concretes, MFH关键词: Foam concrete Porosity Thermal conductivity Mean field homogenization FEM simulations DOI: 10.1016/j.mechrescom.2016.07.004 被引量: 7 ...
This study examines the impact of cork used as sand replacement or stone replacement on the plastic, mechanical, transport, microstructural and thermal properties of mortar and concrete. Mix design variables include the percentage of cork, cork size, and the cork blend. Key findings from this stud...
In this paper, the effect of steel fibers recovered from pneumatic waste, dune sand (D), and its granulometric correction on the thermal conductivity of dune sand concrete was studied. Three types of steel fibers were used (f1, f2, and f3) having the lengths of 20 mm, 30 mm, and 40 ...
Based on the enthalpy-porosity technique, a model of thermal conduction accompanied with solidification and melting processes is developed and numerically analyzed to investigate the thermal response of the brick wall filled with phase change materials (PCM). The thermal response, which is represented ...
