Abstract：This paper evaluates the use of dry sludge as an additive for concrete, for which it must be guaranteed that the resulting concrete has the appropriate mechanical strength and durability. In earlier work on the subject, it was shown that the addition of sludge reduces the mechanical strength of concrete. With the addition of 10% sludge in proportion to the amount of concrete, the mechanical strength decreases significantly, making it unsuitable for medium to highstrength reinforced concrete. One possible area of application would be in the preparation of lowstrength mass concrete that could be used for bases and subbases of roads with light traffic, as filler, etc. We subjected the concrete specimens to different types of accelerated attack in order to evaluate longterm performance and pare them with the reference concrete (not containing sludge). The following tests were made: – Combined wet–dry cycles using fresh water, seawater and water containing 5% sulphates– Accelerated ageing in an autoclave– Accelerated carbonationThe performance of the concrete containing sludge was acceptable and parable to the results obtained for the reference concrete not containing sludge.

The similarities between the developments in distance education generally, beginning with correspondence study in the 1800s to the present day use of the Internet, pared with a similar evolution by library and information science education are stressed. The author concludes that library and information professionals have been given the opportunity to participate in a model which reflects the best human service possible as well as a demonstration of the profession39。 Libraries Analysis Engineering Professional Aspects Libraries Computer ApplicationsDistance educationInternetStudentsInformation scienceLibrariesDetailedSelected Records閱讀文摘：1 3 of 3 selected records from Compendex Ocholla, Dennis N.
