Apr 05, 2017  Powers’ model is a simple approach for estimating the relative volumes of hydration products, porosity, and chemical shrinkage present in portland cement paste as a function of its starting water-to-cement ratio (w/c) and current degree of hydration.It forms an important link between cement composition, microstructure, and performance, necessary for modeling cement-based systems.

Sep 06, 2013  The study was undertaken to model the influence of w/c, limestone filler, and fiber contents on air content, plastic viscosity, compressive and flexural strength characteristics of the DSC. Experimental test results showed that the incorporation of 94.5 kg/m 3 of fiber resulted in a significant improvement in flexural strength (up to 11.5 MPa).

Influence of limestone filler and viscosity-modifying ...

Highlights We study porosity in SCC made without adding limestone filler. The air content in SCC depends on the flowability and viscosity of the material. SCC have a finer pore structure than NVC but content of pores over 0.5 μm is similar. More fluid mixtures permitted more impermeable concrete to be obtained. VMA in SCC as a replacement for filler produces a coarser porous microstructure.

Influence of limestone filler and viscosity-modifying ...

As a result, when specimens are hardened under water, SCC made with limestone fillers tends to shrink, since the water only penetrates the outer layers of the specimen, while the interior is subject to self-desiccation. If the concrete contains substantial air content (3.2%) the water finds it easier to penetrate and the concrete swells.
