TL;DR: In this paper, the authors present the results of observations of scanning electron microscope (SEM) micro/macro crack development and simultaneous measurements of temperature-dependent stress-strain relations of hardened cement pastes (HCP) and mortar under a steady thermal state (up to 500 °C) and a displacement-controlled loading process.

TL;DR: In this article, a displacement-controlled test method for conducting stable fracture tests on tension-weak brittle materials developed in an earlier study has been used for conducting uniaxial tension tests.
Abstract: Results are discussed from experimental and theoretical studies on the tensile failure of short, steel fiber-reinforced mortar/concrete SFRC composites. A displacement-controlled test method for conducting stable fracture tests on tension-weak brittle materials developed in an earlier study has been used for conducting uniaxial tension tests. Several concrete, mortar, paste, and SFRC mixes were tested. Fracture of SFRC in tension is observed to be influenced largely by the matrix softening behavior, the fiber-matrix interfacial response, and its composition parameters. The theoretical model proposed for the idealized SFRC composite takes into account these two primary nonlinear aspects of the failure mechanism in such composites, i.e., (1) the inelastic behavior of the fiber-matrix interface, and (2) the softening characteristics of the matrix. The model, in addition, is realistically sensitive to the reinforcement parameters like fiber volume content, aspect ratio, and the elastic properties of the fiber.

TL;DR: The authors examined the compressive strength of mortar and how the filler effect and pozzolanic reaction of ground palm oil fuel ash (POFA) contribute to this strength, and found that the contribution from the reaction was much more pronounced when the smallest sizes of both materials were considered.

TL;DR: In this article, the authors used high-ALKALI CEMENT-PYREX GLASS MORTAR BARS, which was able to REDUCE the 8-WEEKS EXPANSION by 98 percent with LITHIUM FLUORIDE and 91 percent with lITHIUM CARBONATE.
