โœฆ Synopsis

Hydrated pastes of C3S or alite were prepared with different amounts of integrally bound SO 3 added as gypsum. Strength decreased continuously with increased SO 3 content above about l.O percent. Additions of Al203 into the lattice increased the optimum S03 content to either l.O -1.5 percent or 2.5 -3.0 percent. Several series of pastes underwent marked strength retrogressions at certain SO 3 contents. These strength losses are ascribed to microflaws which may be caused by internal strains.

This paper presents the results of an experimental study on the impact resistance of concrete with compressive strengths of 45โ€“235MPa when subjected to impact by 12.6mm ogive-nosed projectile at velocities ranging from โˆผ620 to 700m/s. The results indicate that the penetration depth and crater diamet

While concrete is one of the most important materials in structural engineering, the fatigue life as a function of the stress amplitude displayed a large scatter and the mechanism of the fatigue behaviour has not been clarified yet. In the present paper, the mechanism was discussed and a stochastic
