TL;DR: In this article, the long-term corrosion behavior of six stainless reinforcing steels embedded in mortar and exposed to chloride media was monitored by electrochemical impedance spectroscopy at the open circuit potential during the period of 2 years.

TL;DR: In this paper, an experimental study was carried out to evaluate the fluidity, flexural strength, compressive strength, shrinkage, bond strength and wear resistance of self-leveling mortar prepared with original phosphogypsum.

TL;DR: In this article, the ability of a shear wave reflection (WR) method to monitor microstructural changes of Portland cement mortar during hydration was investigated, and it was shown that the wave reflection measurements are governed primarily by the degree of the interparticle bonding of the cement particles as calculated from the specific contact area of a simulated microstructure.

TL;DR: In this article, the results of an experimental study on the rheological and mechanical properties of self-compacting mortars made with various types of sands: crushed sand (CS), river sand (RS), dune sand (DS), and a mixture of different sands.
Abstract: Higher cement and fines content is needed in self-compacting mortars (SCMs) to increase their flowability and stability. Different inert fillers and supplementary cementitious materials are usually added. The use of sands rich in fines may be a cost effective alternative source of filler. This paper presents the results of an experimental study on the rheological and mechanical properties of self-compacting mortars (SCMs) made with various types of sands: crushed sand (CS), river sand (RS), dune sand (DS) and a mixture of different sands. The mini-slump flow, V-funnel flow time and viscosity measurement tests were used to study the rheological properties. The experimental results indicate that the rheological properties and strength improve with mixtures of crushed and river sands but decrease with mixtures of crushed and dune sands especially for higher dune sand content. Crushed sand with (10–15%) of limestone fines can be used successfully in production of SCM with good rheological and strength properties. However, a reduction in compressive strength with increasing dune sand content (up to 50%) in mortar with binary and ternary sands was observed.
