Sentence examples for restrained stress from inspiring English sources

The results of a ring test performed to determine restrained shrinkage indicated that at the same age, the cracking potential of expansive mortar based on the stress/strength ratio remained lower than that of normal mortar, which confirmed that the generation of compressive stress at an early age reduced the restrained stress and restrained cracking.

In addition, the restrained specimens under the dry curing condition have higher decrease rate of restraining effect, shrinkage gradient, restrained stress, and cracking potential than those under the sealed condition.

This study experimentally investigated the effects of the reinforcing bar configuration on the shrinkage behavior of high-performance concrete (HPC), including the restrained shrinkage strain, shrinkage gradient, restrained stress, and cracking potential.

In present study, the influence of SAPs as an IC agent on the temperature, autogenous shrinkage, restrained stress, basic tensile creep, and cracking potential of HPC were simultaneously studied by Temperature Stress Test Machine.

Experimental studies on the influence of w/c ratio (0.33, 0.40, and 0.50) on the temperature change, autogenous shrinkage, restrained stress, tensile creep, and cracking resistance of early-age concrete under adiabatic condition and at full restraint degree were conducted using Temperature Stress Test Machine.

In concrete structures higher free shrinkage, higher hydration heat, higher restraint degree, higher elastic modulus and lower creep generally lead to a higher restrained stress and, consequently, to a worse micro-cracking tendency (Gao et al. 2012).

When shrinkage of repair material is restrained, tensile stress, σ(t), is induced which is equivalent to the stress required to pull the repair material at an elongation of Δεsh(t) (Fig. 2c).

The restrained shrinkage stress starts to develop when penetration resistance was 1.5 MPa.

RH could be about 95%, which would reduce the restrained strain to about a third and lead to a tensile stress of 1.0 MPa.

Considering a RH at 0.5 cm of 68.3% (obtained by linear interpolation between the values of RH at the surface and 1 cm), leads to a restrained strain of 1.19 mm m−1 in the superficial layer, and to a maximum tensile stress of 2.8 MPa.

The paper investigates and compares the magnitude of restrained temperature stresses that can be achieved in both a rigid pavement and a flexible pavement with a grouted macadam surfacing.
