Apparatus for measuring the properties of heat transfer by conduction in specials concrete

This work reports the design, development and operation of a hot plate device with guard called HD20 Hot Box to evaluate, under steady-state conditions, the transfer of heat by conduction through test tubes with prism-shaped faces. parallel, and indirectly determine the thermal conductivity of construction concretes with different aggregates. For its design, IRAM 11559, IRAM 11549 and IRAM 11601 standards valid in Argentina were applied. The hot box consists of two main units: the heating unit and the cooling unit. The thermal conductivity values obtained with this apparatus agree satisfactorily with the values published in the literature.

本研究报告了一款名为HD20热盘装置（Hot Box）的防护设备的研发与运行过程，旨在在稳态条件下评估通过棱镜面试管进行的热传导过程，并间接测定不同骨料混凝土的热导率。该设备的设计遵循了在阿根廷有效的IRAM 11559、IRAM 11549和IRAM 11601标准。热盘装置由两个主要单元组成：加热单元和冷却单元。使用该装置获得的热导率值与文献中发表的值相吻合，表现出满意的准确性。
