Test Procedure The procedure for measuring the static modulus of elasticity in compression is described in ASTM C469.

It should also be stated whether a stress-strain curve is needed or only the chord modulus.Implementing Self-Consolidating Concrete Technology in Washington State HPC for the Spliced Girders of Kealakaha Stream Bridge, Hawaii Transfer and Development Length of 0.7-in.(17.8-mm) Diameter Strands in Pretensioned Concrete Bridge Girders Testing and Predicting the Modulus of Elasticity of Concrete This material is based upon work supported by the Federal Highway Administration under Cooperative Agreement No. Any opinions, findings, and conclusions or recommendations expressed in this publication are those of the Author(s) and do not necessarily reflect the view of the Federal Highway Administration.The specifier should also check that local testing laboratories have the equipment available to perform the test on the specified cylinder size.Otherwise, it may be necessary to ship the cylinders to a specialized testing laboratory.However, molded concrete cylinders are usually the same size as those used for compressive strength measurements i.e. Note that it is necessary to determine the compressive strength on companion specimens prior to testing for modulus of elasticity.

The modulus of elasticity is calculated as the slope of the straight line between the 40% compressive stress point and the 50 millionths strain point.As the electrode melts, it supplies weld material which fuses the pieces of steel together.ARCHITECT—A person or firm who prepares the architectural drawings that determine the design and form of buildings.BEAM AND SLAB FLOOR CONSTRUCTION—A reinforced concrete floor system in which a solid slab is supported by beams or girders of reinforced concrete.BEAM BOLSTER—Continuous bar support used to support the reinforcing bars in the bottom of beams.The test procedure does not prohibit the use of the same cylinders for modulus of elasticity and concrete compressive strength provided the loading can be applied continuously.
