水庫淤泥輕質骨材用於製造透水磚之研究

The Application Lightweight Aggregates of Reservoir Sediment Used in Manufacturing Permeable Bricks

指導教授 : 何嘉浚

摘要


將水庫淤泥燒製成輕質骨材之技術,在國內已有多年的研究成果,並且已有廠商投資量產,製成之輕質骨材具有隔熱、隔音、防火等功能,使用於建築工程,符合綠建築之標準;利用輕質骨材取代傳統砂石骨材,拌製輕質混凝土用於橋梁工程,於國道6號已有完成實例,交通部與公共工程委員會正持續推動使用於公共工程建設。水庫淤泥燒製成之輕質骨材,由於具有多孔隙且易透水之特性,若產製成透水磚,適用於景觀或室外鋪面如廣場、人行道、景觀步道及自行車道等,亦可用於河岸及邊坡保護之防災用途;達到廢物再利用及生態環保之目標。 本研究將石門水庫淤泥製成之輕質骨材,篩分為粗(1/2″∼3/8″)、中(3/8″∼1/4″)、細(1/4″∼#8)三種顆粒分類,在固定水泥量(360kg/m3)且固定水灰比條件下,分別製成輕質透水磚,以探討粗、中、細三種不同粒徑輕質骨材之透水係數及抗壓強度關係。實驗室製作及試驗結果顯示,產製之透水磚單位重約1300~1600kg/m3,透水係數10~100×10-2cm/sec,抗壓強度220~320kgf/cm2;在相同水泥量水灰比及相同震動條件下,比較三種粒徑之透水係數為粗>中>細,抗壓強度則為中>粗>細;透水係數大小之排列對應粗中細顆粒之孔隙大小;而抗壓強度中顆粒較大,主要是因水泥漿體在中顆粒之包裹較為完整均勻,顆粒間漿體連結較完整,而充分發揮水泥漿體強度的結果。 本研究另外亦探討將粗、中、細三種粒料混合後之結果作比較參考,結果顯示,混合料之抗壓強度僅略大於粗顆粒磚,而小於中顆粒磚;混合料之透水性能則介於中顆粒與細顆粒之間。

The technology of producing lightweight aggregate from reservoir sludge has been developed for years in Taiwan. Many manufacturers have invested in mass production of lightweight aggregate with various properties such as heat insulation, sound insulation, fire resistance, etc. Such material has been used in construction engineering and meets green building standards. Traditional sand and gravel aggregates can be replaced with lightweight aggregates to mix lightweight concrete and it was successfully used for the bridge construction on national rout 6. The Ministry of Transportation and Public Constructions Committee continue to promote the use of lightweight aggregate in public constructions. The lightweight aggregate produced by using reservoir sludge, due to its porous characteristic, when used to manufacture lightweight permeable bricks, are suitable for use in landscape or outdoor pavement, such as square, sidewalk, landscape trails and bike paths, etc. It can also be used at riverside and slope protection for disaster prevention purposes. The lightweight aggregate achieves waste recycling and ecological environmental protection goals. In addition to the efficient resource utilization of reservoir sludge, the lightweight aggregate meets the concept of green environmental protection. In this study, the lightweight aggregate manufactured using Shimen Reservoir sludge was sieved and classified according to particle size into three groups: coarse (1/2″to 3/8″), medium (3/8″to 1/4″) and fine (1/4″~ # 8). Water-permeable bricks were made using each group of lightweight aggregate under the condition of fixed amount of cement (360kg/m3) and water-cement ratio to investigate the relationship between coefficient of permeability and compressive strength of lightweight aggregate of coarse, medium and fine particle sizes. The permeable bricks produced in this study weigh about 1300~1600kg/m3 having coefficient of permeability of 10~100×10-2cm/sec and compressive strength of 220~320kgf/cm2. With the same amount of cement, water-cement ratio and vibration condition, the comparison result of the coefficient of permeability was coarse > medium > fine group. The result of the compressive strength was medium > coarse > fine group. The result of coefficient of permeability corresponds to the size of void of the particle size from large to small while the result of compressive strength is greater for medium particle size. This is because medium size particles are wrapped more completely and evenly in cement paste and the paste linkage between particles is more complete and thus fully giving the strength of cement paste. Further, the three groups of materials were mixed and compared. The results revealed that the compressive strength of the bricks made of mixed material is only slightly greater than the bricks of coarse particles and less than the bricks of medium particles while the permeability of the bricks made of mixed material is in between of the bricks of medium particles and those of fine particles.
