Properties of self consolidating concrete for prestressed members

Greater total creep, but a smaller creep coefficient was observed for LWSCC compared to SCC.

The creep coefficients at one year for specimens loaded at one day were 2.0 for LWSCC and 2.9 for SCC.

They were proportioned with 0.34 and 0.38 w/cm and had slump values of 150 mm.

Mechanical properties of SCC were compared to code provisions to estimate compressive strength, elastic modulus, and flexural strength.

The results show that the compressive strength varied from 1.5N/mm2 to 6.5N/mm2 for the replacement levels at 48 days of curing. [5] BS1881; Part 3 (1992) Method for Determination of Density of partially compacted Semi-dry fresh Concrete, British Standard Institution.

In this paper the protocols suite selected for comparison are AODV, DSR, TORA and OLSR ad- hoc routing protocols, as these were the most promising from all other protocols.

Abstract: Spatial Data Infrastructure (SDI) is the geographic data framework implementation of data, metadata, users and tools in terms of data infrastructure that are connected in interactive way to allow the flexibly and efficient use of the data. Our system will allow E-examinations to be taken securely under the supervision of invigilators and with subjective assessment in it, with instantaneous availability of results.
