Bulk production of silicate glasses is based around a narrow range of soda–lime–silica compositions and as a result any variation in mechanical properties with composition is normally considered to be of little interest. However, studies by a range of authors over the last 50 years or so have demonstrated some intriguing

In this study, the properties and structural failure of natural hydraulic lime (NHL) and metakaolin-air lime (MK-AL) due to NaOH, NaCl and Na 2 SO 4 erosion were studied in terms of macroscopic variation, mechanical property deterioration and internal three-dimensional (3D) structure evolution. The results obtained by XRD, TG-DTA and MIP tests ...

TiO 2 is an important oxide for property modifications in the conventional soda lime silicate glass family. It offers interesting optical and mechanical properties, for instance, by substituting heavy metals such as lead in consumer glasses. The compositional effects on the hardness, reduced elastic modulus and crack resistance as determined by indentation of …

Several studies investigated the impact of shiv particle size on the hygrothermal and mechanical properties of hemp-lime composites. While they all reported the relevance of this impact, their findings may seem discrepant, raising the need for further investigation of the impact of particle size on hygrothermal and mechanical properties of hemp-lime composites.

This study employed thermal poling at 200°C as a means to modify the surface mechanical properties of soda lime silica (SLS) glass. SLS float glass panels were allowed to react with molecules constituting ambient air (H 2 O, O 2, N 2) while sodium ions were depleted from the surface region through diffusion into the bulk under an anodic potential.A sample poled in inert …

Natural hydraulic lime (NHL) has been used as a binder for mortar production since antiquity [1], [2].It is produced through the relatively low-temperature calcination and subsequent slaking of marly limestones (limestones naturally containing silicate and aluminate compounds) [3], [4].In antiquity its use was either on purpose (areas of high humidity or cases where faster …

In the present paper mechanical properties, microstructure and phase composition of binder produced by mixing Metakaolin (MK) and slaked lime in 4:1 proportion by weight have been studied.
