Based on round-robin testing, the pooled single operator standard deviation of this test method is 0.43 for water sources of choice with a silt density index (SDI) of 0.4 to 15. Nine operators from five laboratories participated using the test water of their choice.
5. ASTM : C 140-03 Standard test methods for sampling and testing concrete masonry units and related units. We are thankful to Sir Kaushal Kishore for publishing his unpublished research paper here on the website. This would be of great use to all the civil engineers who work are looking for information regarding Testing of Concrete Blocks .
Abstract: The aim of this study is to investigate the characteristics exhibited by three different grades of concrete using mix design approach. From the result of the sieve analysis, it shows that the sands used for the experiment is a well graded sand of zone 1 of BS882 parts 2 (1973).

db.collection.distinct(): The db.collection.distinct() method is used to returns an array of documents that have distinct values for the specified field. See also syntax, parameters, examples and explanation.
Example: MongoDB: db.collection.aggregate() method . The following MongoDB query starts matching into the restaurants collection for documents with borough equal to "Brooklyn" and group the matching documents by cuisine field and calculates the number of times each group appears.
ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates.

STRESS TESTING AS A RISK MANAGEMENT METHOD The position of stress testing in risk management Stress testing is arelatively new yet highly relevant field in risk management and generally in bank management.One of the first documents to focus on stress testing was the report published by the Deri-vatives Policy Group1 in 1995, which recommended
Temperature, aggregate size and the amount of mix water can also have an impact. The pressure method is used for mixes containing normal to heavy-weight aggregate. Applying a predetermined pressure to a calculated sample volume of concrete squeezes out the air. This results in a pressure drop that corresponds to the percentage of

1. Motivation and purpose. Following recent work by Appadurai (2001) and Ray (2006), several papers in development economics literature have attempted to empirically investigate the intertwined relationship between aspirations and poverty (e.g., Macours and Vakis, 2009; Bernard et al., 2011; Beaman et al., 2012).It is noticeable, however, that the indicators used to characterise aspirations ...
