Modeling of Hydration, Compressive Strength, and Carbonation of Portland-Limestone Cement (PLC) Concrete
Limestone is widely used in the construction industry to produce Portland limestone cement (PLC) concrete. Systematic evaluations of hydration kinetics, compressive strength development, and carbonation resistance are crucial for the rational use of limestone. This study presents a hydration-based model for evaluating the influences of limestone on the strength and carbonation of concrete. Firs...

متن کاملSEM investigation of microstructures in hydration products of portland cement
Portland cement is the one of the main ingredients in the manufacture of many building materials include concrete composites. The phase composition of hydration products is controlled by means of XRD and DTA/TG analysis. Observations of phase changes and microstructure of maturing cement pastes can also be observed using scanning electron microscopy (SEM) techniques combined with chemical analy...
متن کاملInteraction of tartaric acid during hydration of Portland cement
Hydration of Ordinary Portland cement (OPC) in the presence of tartaric acid has been studied by using different techniques. Calorimetric studies have shown a rapid enhanced heat evolution within 5 min of hydration in presence of 1.0 wt% tartaric acid with a strong retardation of silicate phase hydration. DSC and X-ray diffraction studies have confirmed the formation of calcium tartarate hydrat...
متن کاملCompressive strength of Portland cement pastes and mortars containing Cu-Zn nano-ferrite
This study is concerned with the synthesizing of Cu-Zn nano-ferrite particles in the laboratory applying simple techniques. The morphology of the synthesized nano-particles was analyzed using Transmission Electron Microscopy (TEM), and the minerals were identified using X-ray diffraction (XRD). The nano material was used to replace 1- 4 percent by weight of Portland cement in cement pastes and ...
