人造輕粒料(LWA)的生產係直接利用粉煤灰及磨細高爐礦渣（爐石）以鹼激冷結方式生產並添加水泥。鹼性活化劑溶液採用氫氧化鈉為唯一凝固劑。使用冷結型輕質粒料作為粗骨料製造自充填混凝土。本研究的主要目的是探討添加稻殼灰對冷結輕質粒料自充填混凝土性能的影響。 本研究觀察LWA和SCLWAC特性 。研究結果顯示，輕粒料的單點壓碎強度範圍28天時在10.4-12.8Mpa範圍。輕粒料的單位重介於1001~1095kg/m3之間。新拌自充填輕質粒料混凝土單位重約2000kg/m3，56天抗壓強度範圍落在32.7-64.7Mpa。研究結果也表明了使用最多20%的稻殼灰取代水泥，能夠得到較佳的混凝土強度與耐久性能。

Artificial lightweight aggregate (LWA) was produced by using the binary of fly ash (FA), ground granulated blast furnace slag (GGBFS) by the cold bonding method without cement additives. Alkaline activator solution (only sodium hydroxide) was the wetting agent acting as a coagulant. Self-consolidating concrete was produced by cold bonded lightweight aggregate as coarse aggregate. The objective of this thesis is to investigate the effect of adding residual rice husk ash (RHA) on properties of self-consolidating lightweight aggregate concrete (SCLWAC). The properties of LWA and SCLWAC were investigated. The crushing strength of LWA was in the range of 10.4-12.8 MPa at 28 days. The unit weight of LWA ranged from 1001-1095 kg/m^3. The fresh properties of SCLWAC with unit weight around 2000kg/m^3.
