輕質混凝土係以輕質骨材取代一般使用之常重骨材所製成的混凝土材料,具有質輕、隔熱、耐火性強、耐震性佳、且強度夠的優點。歐美先進國家於二十世紀初即開始生產輕質混凝土,並使用於結構工程與非結構性用途上。位於地震帶上的台灣地區,近年來高樓及大型公共工程遽增,且因屬於亞熱帶,能源節約需求日益殷切,發展輕質混凝土以取代傳統混凝土,就整體經濟效益而言,有十足的重要性與需求性。

緻密高性能輕質骨材混凝土耐久性之研究以緻密配比法拌製高性能輕質混凝土進行耐久性質之量測。依三種不同比重水庫淤泥再生輕質骨材,來取代普通骨材所拌製之輕質混凝土。1.輕質混凝土以緻密配比法新拌性質可達高流動化要求。

2.全輕質混凝土7天強度可達 28 天強度的 80 ﹪- 90 ﹪。

輕質及常重結構混凝土版之防火性能比較

依據CNS 12154 的標準升溫曲線對圓柱試體及版試體加熱之後,取出試體,觀察其表面之火害破壞情形 與常重混凝土比較,判斷其優劣性輕質與常重混凝土版試體未先進行完全烘乾處理即進行防火試驗時,輕質混凝土試體將會因內部產生較高蒸汽壓力而發生表面剝落的情形,甚至導致破壞,常重混凝土者則較不會發生表面剝落的情形。

預鑄輕質混凝土柱之性質研究將柱試體以位移控制法施加軸向荷重至完全破壞為止,藉以探討輕質骨材混凝土作為柱構件材料之可行性。探討是否可取代常重混凝土。1.輕質骨材混凝土柱之延 展性稍差。

2.輕質骨材混凝土柱與常重混凝土柱極為相似,因此可以取代常重混凝土柱使用。

輕質混凝土具有質輕、高強度、隔熱、消音、防水、抗火、耐久、體積穩定、施工方便、經濟等 諸多特性。由三種不同方式來判別與一般常重混凝土優劣點,而其結果也令人滿意。而使用材料環保,也讓輕質混凝土也漸趨普遍化,對於環境也是一大幫助。

最主要是翻譯第一段跟最後一段。感謝你的幫忙。

    Lightweight concrete is based on the general use of lightweight aggregate replacement made ​​of normal weight aggregate concrete material, with light, heat insulation, fire resistance, shock resistance, and strength enough advantages. Advanced countries in the early twentieth century began to produce lightweight concrete, and make for structural engineering and non-structural purposes. Seismic belt located in Taiwan in recent years, dramatic increase in high-rise buildings and large public works, and because of a subtropical, increasing demand for energy conservation, development of lightweight concrete to replace the traditional concrete, the overall economic benefits, there are full of important sexual and demand sex.第一段

    Lightweight concrete with a light weight, high strength, heat insulation, noise, water, fire resistance, durability, volume stability, construction convenient, economical, and many other features. Composed of three different ways to determine normal weight concrete with the general advantages and disadvantages, but the outcome is satisfactory. The use of materials, environmental protection, but also to lightweight concrete has become increasingly generalized, for the environment is also a big help.最後一段
