Mechanical properties of concrete containing 100% treated coarse recycled concrete aggregate
TL;DR: In this paper, an environmental friendly method for enhancing mechanical properties of recycled aggregate concrete (RAC) is proposed by using sodium silicate and silica fume, which can improve compressive strength up to 33-50%, splitting tensile strength 33-41%, and elastic modulus 15.5-42.5%.

Factors affecting bond development between Ultra High Performance Concrete (UHPC) and steel bar reinforcement
Mo Alkaysi,Sherif El-Tawil +1 more
TL;DR: In this paper, a series of bar pull out tests was performed in order to characterize the bond strength of a non-proprietary UHPC blend, and the tests were conducted using plain and epoxy-coated grade 60-bars with nominal diameters of 13mm, 16mm, and 19mm.

Microstructural characteristics, porosity and strength development in ceramic-laterized concrete
Paul O. Awoyera,Paul O. Awoyera,Joseph O. Akinmusuru,Andrew Dawson,Julius M. Ndambuki,Nick Thom +5 more
TL;DR: In this article, the authors explored the relationship between morphological changes, porosity, phase change, compressive, and split tensile strength development in a ceramic-laterized concrete, and selected samples with higher 28 day crushing strength, and the reference mix, were further characterized with more advanced analysis techniques, using the mercury intrusion porosimetry (MIP), thermogravimetric analysis (TGA), X-ray Diffractometer, and SEM (backscatter electron mode-for assessment of the interfacial transition properties between aggregates and paste).
