Development of high early strength concrete for prestressed concrete applications / by Zia, Paul,1926-(CARDINAL)167573; Hillmann, Randall S.; North Carolina.Department of Transportation.(CARDINAL)145570; North Carolina State University.Center for Transportation Engineering Studies.(CARDINAL)182954; United States.Federal Highway Administration.(CARDINAL)139839;
Includes bibliographical references (pages 37-39).Final report.Sponsored by the North Carolina Department of Transportation and the Federal Highway Administration.This report describes the development of high early strength concrete with locally available materials in North Carolina and normal production and curing procedures used in precast/prestressed concrete plant. After many trial batches, two different mixture proportions were developed in the laboratory and three additional mixture proportions were developed for field production. The mixtures contained approximately 850 lbs/cy (504 kg/cu m) of Type III cement, 1027 lbs/cy (609 kg/m) of fine aggregate, and 1764 lbs/cy (1047 kg/m3) of course aggregate with a W/C of 0.34. Melamine-based HRWR was used to enhance the workability with a slump ranging from 3.5 in (89 mm) to 7.5 in. (191 mm). Air entraining agent was also used to achieve an air content of 3% to 4.5%. The concretes developed a compressive strength of 7,000 psi (48 MPa) in 18 hours and 10,000 psi (69 MPa) in 28 days.

The history of the prestressing strand development length equation / by Tabatabai, H.(Habib)(CARDINAL)319122; Dickson, Timothy J.; United States.Federal Highway Administration.Office of Engineering & Highway Operations Research and Development.(CARDINAL)286896; Construction Technology Laboratories (Portland Cement Association)(CARDINAL)286967;
Includes bibliographical references (pages 105-106).Introduction -- History of the development length equation -- Development length parametric study -- Summary -- Appendices -- References.Final report;A research study was conducted to determine the history of the AASHTO prestressing strand development length equation and to evaluate the significance, with respect to development length, of changes in the AASHTO provisions for the determination of steel stress at ultimate flexural strength. The accuracy of the AASHTO provisions in determining steel stress at ultimate flexural strength was also evaluated for a number of typical cross sections used in bridge construction. The strand development length equation was first introduced in the 1963 ACI Building Code and was adopted by AASHTO in 1973. The original research that formed the basis for the equation was conducted at the Portland Cement Association (PCA) in the late 1950s and early 1960s.Sponsored by Office of Engineering and Highway Operations R&D, Federal Highway Administration, under contract no.
