Download Treatment of Imperfections in Precast Structural Elements Book in PDF, ePub and Kindle
fib Bulletin 41 addresses the most common types of imperfections encountered during the manufacture, stacking, transport and erection of precast concrete structural elements, and suggests a number of possible remedial actions. The remedial actions depend on the severity of the imperfection, the feasibility of repair and the consequences on the intended use of the concrete member. Imperfections in concrete structures are impossible to avoid and can range from minor surface blemishes to major structural defects. Because many imperfections are at the limits of specified quality deviations, or are not included in the acceptance criteria, the problem is more complex than a decision between rejection or acceptance. This document deals with precast concrete elements that do not meet the quality as intended in the design. It compares imperfections in quality to the specified requirements so that the effect of the imperfection can be evaluated. Recommendations are provided on methods to prevent such imperfections, the effect they can have and any necessary actions for rectification. The bulletin applies to prefabricated concrete members made of reinforced or prestressed normal weight concrete. Products include beams and columns, concrete walls, hollow core slabs, double tees, planks and beams for beam and block floors. Water retaining structures are outside the scope of this document.

Download Determination of Acceptance Criteria for Prestressing Strand in Pre-tensioned Applications Book in PDF, ePub and Kindle
ASTM recently adopted the Standard Test Method for Evaluating Bond of Seven-Wire Steel Prestressing Strand as ASTM A1081, a pull-out test procedure developed for verifying the ability of steel strands to bond to cementitious materials prior to their use as tensile reinforcement in prestressed concrete sections. The required by ASTM International precision and bias statement has not been developed for this test method. In addition, a minimum threshold value that will ensure only adequately bonding strand sources will be accepted has not yet been applied to ASTM A1081. The test method was developed after findings that prestressing steel strand sources of identical type and grade vary significantly as far as their bonding capacity. Bond is a crucial aspect of the prestressing force being transferred into the concrete, and insufficient bonding action can result in the prestressed concrete section lacking in capacity to sustain the loads that it was designed for. After an initial survey of the pull-out strength of North American Strand in mortar, three strands of differing pull-out strengths were selected for inclusion in further testing. A precision and bias statement for ASTM A1081 was developed by first performing ruggedness testing to determine how the results are affected by allowable variations in methods and materials, and followed by an inter-laboratory study to determine the reproducibility of the test method. Once the precision and bias statement for the standard test method was developed, the same strand sources were tested for their performance in concrete beams. Statistical analysis of the flexural beam testing data and correlation with the prestressing strand sources' ASTM A1081 test results was performed, and the industry was provided with minimum acceptance criteria for prestressing strand tested by ASTM A1081, along with recommendations regarding the standard test method and aspects of prestressed concrete design.
