Concrete Mix Design - Background Data

http://concrete.union.edu/backgrnd.htm

ACI 211.1-91, Reapproved 2009, states: To the extent possible, selection of concrete proportions should be based on test data or experience with the materials actually to be used. The following information for available materials will be useful:. 149; Sieve analyses of fine and coarse aggregates. 149; Unit weight of coarse aggregate. 149; Bulk specific gravities and absorption of aggregates. 149; Mixing-water requirements of concrete developed from experience with available aggregates.

2

Concrete Mix Design - Scope

http://concrete.union.edu/scope.htm

ACI 211.1-91, Reapproved 2009. This Standard Practice describes methods for selecting proportions for hydraulic cement concrete made with and without other cementitious materials and chemical admixtures. This concrete consists of normal and/or high density aggregates, with a workability suitable for usual cast-in-place construction. Contact A. Ghaly at ghalya@union.edu. Concrete Mix Design Homepage.

Concrete Mix Design - Chemical Admixtures

http://concrete.union.edu/chemical.htm

EFFECTS OF CHEMICAL ADMIXTURES ON CONCRETE PROPORTIONS. ACI 211.1-91, Reapproved 2009, states: Chemical admixtures, pozzolanic, and other materials can be added to concrete mix to alter some properties or to produce desired characteristics. Additives are used to affect the workability, consistency, density, strength, and durability of the concrete. Contact A. Ghaly at ghalya@union.edu. Concrete Mix Design Homepage.

Concrete Mix Design - Basic Relationship

http://concrete.union.edu/basic.htm

ACI 211.1-91, Reapproved 2009, states: Concrete proportions must be selected to provide workability, consistency, density, strength, and durability, for the particular application. The property of the concrete that determines its capacity to be placed and consolidated properly and be finished without harmful segregation. It is the relative mobility of the concrete mixture, and measured in terms of the slump; the greater the slump value the more mobile the mixture. If the temperature rise of the concrete ...

研究所筆記本: 大氣的衛星遙測

http://twcds-1.blogspot.com/2009/04/blog-post_01.html

遙測,又稱為遙感探測,一般定義為利用儀器偵測目標物反射或放出的電磁波來決定其物理性質的技術。遙測儀器對目標物只進行間接的和遠距離的,而不是和目標物直接接觸的測量。根據這個定義,人類的眼睛是最基本的遙測儀器。在氣象學的範圍內,使用氣象雷達、激光電達、多普勒雷達以及氣象衛星等工具來觀測大氣現象都屬於遙測的領域。 廣義的遙測還包括利用磁性和重力等方法進行測量的技術。這些方法在探測地球內部構造方面特別有用,在地球物理學中相當受到重視。利用聲波雷達來探測低層大氣也屬於遙測的範圍。從這個觀點來看,人類的耳朵也是一種遙測儀器。 一) 地球上有許多地區,如南北半球的海洋、沙漠及極區等地,測站稀少,天氣資料缺乏。衛星資料正好填補這些空隙。從衛星雲圖可以看出大氣大尺度運動的特徵,包括風暴系統、鋒面、高空槽脊、急流、霧、層雲、海冰狀況、積雪以及高空風向和風速。衛星資料連同其他資料也提供等壓面高度,做為天氣...地球資源遙測使用飛機或人造衛星,攜帶儀器,對地面進行觀測,從事資料的蒐集,以供資源調查或環境監視之用。基本上說,大氣遙測和地球資源遙測...一) 地面分辨率。地球資源遙測要求的分辨率較高,例...二) 大氣的影響&#1...
