.... The impacts of calcined zeolite were investigated in the hydrated system with the replacement of portland cement up to 20 % by mass on hydration kinetics (i.e., heat of hydration, setting time, chemical shrinkage, degree of hydration), drying shrinkage, and compressive strength. Results revealed...

... properties. The test related to permeability like water absorption, sorptivity, permeability, and drying shrinkage has been performed. Mercury intrusion porosimetry test was performed to validate durability results. The results indicate that 30 % of river sand can be replaced with waste marble sand...

... % compared with the control mixture. Moreover, it was noted that the LWA with higher absorption increases plastic shrinkage cracks for concrete decks under severe conditions. 15 05 2022 15 12 2022 07 02 2023 restrained shrinkage drying shrinkage plastic shrinkage slag cement pre...

..., drying shrinkage, and flexural strength of portland limestone cement (PLC) mixtures. Eighty mortar and paste mixtures were prepared using Type II/V ordinary portland cement (OPC), PLC, and OPC with ground limestone (OPC + LS) with and without supplementary cementitious materials (SCMs). The PLC was made...

... materials ratios of 0.40, 0.44, and 0.50 and fly ash levels of 0, 20, and 30 % were studied. Mixtures were tested for workability, entrained air, drying shrinkage, and the ability to maintain a 28 MPa compressive strength requirement. The compressive strength requirement was met by each mixture investigated...

...Alireza Bagheri; Armin Jamali; Mina Pourmir; Hamed Zanganeh The positive effect of increased duration of curing in enhancing strength and durability of concrete is well established. However, there have been reports suggesting that longer curing times can result in increased drying shrinkage and can...

... quality and marine life. This study was carried out to investigate whether this brine could potentially be used to manufacture cementitious materials. The effects of different concentrations of simulated reject brine on hydration kinetics, compressive strength, and drying shrinkage of cement paste...

... (namely, ordinary portland cement (OPC) and OPC with 20 % fly ash replacement), and two types of water (tap water and seawater). The autogenous and drying shrinkage behavior of these mixtures are examined using ASTM standard test methods for 65 days. The use of seawater as mixing water increased...

... with intermediate-sized prewetted LWA is effective in reducing drying shrinkage in concrete made with moderate w/b ratios. Partial replacements of cement with slag cement and silica fume induce increased first-day expansion and reduce shrinkage. A further increase in first-day expansion and a reduction in shrinkage...
