Study on the Permeability of Modified Bentonite Slurry in Landfill

Advances in Materials Science and Engineering, 2020
The impermeability of cutoff wall is one of the most important factors affecting the life of landfill. Hence, we used sodium carboxymethyl cellulose to modify bentonite and developed a modified bentonite-cement-fly ash antiseepage slurry with a low ...

The effect of ultrasound on the setting reaction of zinc polycarboxylate cements

Journal of Materials Science: Materials in Medicine, 2010
The set of glass ionomer cement (GIC) is accelerated by application of ultrasound. Although GIC has somewhat displaced zinc polycarboxylate cement (ZPC) in dental applications the latter is still extensively used. Like GIC, it provides direct adhesion to tooth and can provide F release, but is more radiopaque and biocompatible than GIC. The aim of this

Evaluating the high‐temperature resistance of self‐compacting mortar incorporating waste andesite powder as a mineral admixture

Structural Concrete, EarlyView.
Abstract Significant amounts of waste material are generated at various stages of andesite stone processing, including mining, cutting, and polishing. Despite this, limited research has been conducted on the potential use of waste andesite powder (WAP) as a mineral admixture.

Micromechanics analysis of thermal expansion and thermal pressurization of a hardened cement paste [PDF]

Cement and Concrete Research (2011), 2011
The results of a macro-scale experimental study of the effect of heating on a fluid-saturated hardened cement paste are analysed using a multi-scale homogenization model. The analysis of the experimental results revealed that the thermal expansion coefficient of the cement paste pore fluid is anomalously higher than the one of pure bulk water.
