In this research, the properties and cementitious performance of thermally activated cement pastes (referred to as DCPs) are investigated. Hydrated prepared from Portland slag blended were subjected different thermal treatments: 350 °C for 2 h, 550 24 h 750 h. The reactivity SCM DCPs characterised well their effect on mechanical hydration new cements incorporating supplementary materials (SCMs). It was observed that temperature duration treatment increased grindability BET specific surface...

Composite materials are increasingly used in various vehicles and construction parts, necessitating a comprehensive understanding of their behavior under varying thermal conditions. Measuring the thermo-mechanical properties with traditional methods such as tensile testing or Dynamical Mechanical Analysis is often time-consuming requires costly apparatus. This paper introduces an innovative non-destructive method for identifying orthotropic engineering constants composite test sheets...

To solve the contradiction between injectability of profile control agent and its ability in low-permeability reservoirs, a novel in-situ polymeric microsphere is proposed. In-situ-polymeric (ISPM) emulsion was injected into formation by polymerization to form microspheres for control. The composed divinylbenzene, acrylamide monomer, surfactant fatty acid polyoxyethylene ether sulfate, sorbitan oleate p-hydroxyanisole. An ISPM particle diameter 1.88 30.60 μm achieved adjusting amount Span80....

The application of FE simulation in manufacturing processes and virtual prototyping increases every day. In order to allow accurate simulations, correct constitutive models are needed as input the software. A modern promising way identify material parameters those is “inverse modeling”.

Quantitative shearography applications continue to gain practical importance. However, a study of the errors inherent in measurements, related calibration instrument and correction results, is most often lacking. This paper proposes procedure for out-of-plane with Michelson interferometer. The based on measurement known rigid-body rotations flat plate accounts local variability shearing distance. further compensates sensitivity vector separates two deformation gradients when they are coupled...

Copper slag (CS) remains a challenging industrial by-product with relatively small utilization fraction. The present study investigated the development of one-part alkali-activated cements based on CS, ground granulated blast furnace (GGBS) and mixture two as precursor. We 5 to 15 wt% solid sodium metasilicate (Na2SiO3) disilicate (Na2Si2O5) alkaline reagents. Isothermal calorimetry showed that reactivity system was higher for samples, early reaction cumulative heat released. Metasilicate...

The ability to manufacture accurate parts in single point incremental forming is dependent on the capability properly predict accuracy response surfaces of individual features and feature interaction combinations formed using uncompensated tool paths. Recent studies show that profiles obtained are choice material used for forming, terms magnitude, geometric shape nature errors (under over forming). In this paper, an attempt made capture effect properties surfaces. modeled Multivariate...

ABSTRACT Regenerated cellulose microspheres (RCM) with controllable sizes and architectures are prepared via electrospraying from environmental‐friendly NaOH/Urea aqueous system. The particle size shape of RCM is mainly dependent on the interplay among electrical force, surface tension, viscous force. Particle can be reduced to a certain extent by increasing voltage decreasing electrode spacing, solution concentration, degree polymerization, flow rate. deformation droplets, which peculiarly...

Laminated composites materials are mostly used in dynamically loaded structures. The design of these structures with finite element packages is focused on vibrations, elastic deformations and failure control. Damping often neglected because its assumed secondary importance also dearth information relevant material properties. This trend prone to change as it now realised that damping plays an increasingly important role vibration comfort, noise radiation crash simulations. paper shows a...

The simulation of a resin flow through porous medium by FE-models has become very important aspect for the design high-performance RTM produced composite part. key parameter to perform simulations is fibre reinforcement permeability. Unfortunately, permeability measurements are not yet fully standardized and thus many different set-ups have been proposed. A major problem in comparing always fact that there exists no reliable reference material on which comparative measurement can be...

A simplified method to determine the strain distribution during incremental forming of a cone is proposed in this paper. Because symmetry deformed part, can be derived using results obtained from limited number consecutive tool contours instead going through whole process. Comparisons made between measured and simulated show that applied encountered such kind process where axi-symmetric parts are formed.

In general, phosphate cements have a very rapid setting reaction at room temperature. The same holds for copper slag-based cements. This means that using them as binder, instance mortar, is always possible on small scale, but difficult large scale. this paper, the heat treatment of slag was shown to be an effective way increase time and keep mix workable adequate period. main objective research examine changes in phase composition quenched after exposure 500 °C evaluate impact these...
