4.3.2 Creep has been conclusively shown to be directly proportional to paste content throughout the range of paste contents normally used in concrete. Thus, the creep characteristics of concrete mixtures containing aggregate of maximum size greater than 50 mm [2 in.] may be determined from the creep characteristics of the minus 50-mm [minus 2-in.] . This newly developed test setup allowed testing the long-term tensile creep of ultra-high performance concrete (UHPC) for the first time.

The main thesis of the study is that tests performed using these spring-loaded frames is not a creep test in the sense that the force acting on the specimen is not held constant while the specimen undergoes time-dependent strain.
Creep of Concrete
6.2.3 Different geometries as mentioned in 1.1.6 may have different size requirements for obtaining geometry and size independent creep crack growth rate data. It is therefore necessary to account for these factors when comparing da/dt data for different geometries or when predicting component life using laboratory data. For these reasons, the . Several test configurations for the flexural creep test can be found in the literature. Participant laboratories in the RRT have developed or adapted their methodology and the main characteristics are summarised in Table 4.2.Some of the differences between laboratories are given by the national reference standard available to characterise the concrete flexural .
ASTM E139 – Creep, Creep Rupture and, Stress Rupture Test of Metallic Materials. ASTM E139 test method involves creep and rupture tests for metallic materials. The creep test measures the load-carrying capacity of the material up to limited deformation. The rupture test measures load carrying capacity as a function of time.

Teller of the U.S. Bureau of Public Roads (now FHWA).Robert E. Philleo authored the chapters appearing in ASTM STP 169A, 1966, and ASTM STP 169B, 1978, under the title “Elastic Properties and Creep” Mr. Philleo died in May 1990, shortly before this revision, ASTM STP . Abstract. Creep failure is due to the interconnection of microcracks in concrete when the material is placed under continual high stress. High-stress creep failure is a rarely researched phenomenon and currently lacks mathematical explanation. Previous investigations of high-stress creep failure in concrete from around the world have shown that shorter product .

Abstract. A new device, the Creep Testing Apparatus (CRETA), has been developed for use in determining the viscoelastic properties of joint sealant. Creep tests were conducted on two types of silicone sealant: self-leveling (SL) and non-self-leveling (NS). The results appear to indicate that the silicone sealant tested is a linear viscoelastic material and .
