摘要

本文目的在探討屋頂混凝土建材對隔熱效果的影響，使用不同摻料：輕質粒料（大／中／小）、相變化材料、發泡劑、隔熱漆，試驗25cm*25cm*2.5cm之方形試體，進行單面模擬日照加熱方式進行熱傳導試驗。利用熱傳導公式，求得混凝土之熱傳導係數與熱傳透率，故利用此結果與根據內政部建築研究所「建築技術規則－綠建築篇」規範，本文發現除了純水泥磚大於此數值，其餘添加不同摻料之混凝土磚皆可有助於降低室內溫度。實驗結果顯示，加入不同摻料可增加混凝土的熱阻。

This paper aims to investigate the roof concrete building materials for insulation effect, using different admixtures: lightweight aggregate (large/medium/small), phase change materials, foam, insulation paint, testing 25cm*25cm*2.5cm the square specimens, single-sided approach to simulate sunlight heating heat conduction tests. Heat conduction equation, and seek concrete thermal conductivity and heat transmission rate, so take advantage of this result with the Building Research Institute under the Ministry of the Interior ＂Building Technical Code-Green Building papers' specifications, we find that in addition to pure mud is greater than this value, add the remaining different admixtures of concrete bricks can help reduce the indoor temperature. Experimental results show that adding different admixtures can increase the thermal resistance of concrete.
