Hybrid cements: Towards their use as alternative and durable materials against wear

Chapter 6.11: Cements as Porous Materials

Use of pulp mill inorganic wastes as alternative liming materials.

A laboratory aerobic incubation study was performed during 18 weeks under controlled conditions to assess the effects of applying different doses of pulp mill inorganic wastes on the physical-chemical properties of an acid Dystric Cambissol. Three different inorganic wastes were tested - wood ash, dregs and grits, and an agriculture limestone was used as reference. Results showed that increasin...

Glass-ionomer cements as restorative and preventive materials.

This article focuses on glass-ionomer cement (GIC) and its role in the clinical management of caries. It begins with a brief description of GIC, the mechanism of fluoride release and ion exchange, the interaction between GIC and the external environment, and finally the ion exchange between GIC and the tooth at the internal interface. The importance of GIC, as a tool, in caries management, in m...

Bone cements and their potential use in a mandibular endoprosthesis.

Bone cement was first used in the 1950s. Since then many modifications have been made and alternatives developed to the original polymethylmethacrylate (PMMA) cement. In view of the use of bone cement in a novel mandibular endoprosthetic system, we performed a review of the current literature on this material. Different cements are described and their potential use in a mandibular endoprostheti...

Use of Superplasticizers in Concrete and Their Compatibility with Cements

This investigation formed a prior stage of a research programme which was concerned about performance of various types of concrete under sulphate attack. It was intended to investigate into the use of superplasticizers in concrete, the aspect of compatibility among available cements & superplasticizers and to choose a suitable pair of them for the programme. Three different types of available c...
