Impact of Changing Microstructural Compositions of Lime Based Mortar on Flexibility: Case Study of Sustainable Lime-Cement Composites

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 6, Page # 1488–1498, 2020; DOI: 10.25046/aj0506179
Abstract:

Lime mortar, an age-long building material is primarily popular for its flexibility, the basis of its ability to accommodate masonry deformation, hence durability. However, lime’s characteristic delayed setting/hardening time, low mechanical strength and poor internal cohesion often characterised by volumetric changes have put its use into decline. These shortcomings have therefore relegated relevance of this…

Effect of Heat Retention Time and Pouring Temperature on Graphite Shape and Mechanical Properties of Gray Cast Iron

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 6, Page # 838–844, 2020; DOI: 10.25046/aj0506100
Abstract:

In this study, the ASTM A48 Class 30 gray cast iron was cast in a medium frequency induction furnace. The ultimate tensile strength (UTS), ultimate flexural strength (UFS) and microstructure were determined in accordance with ASTM E8/E 8M-80 and ASTM A438-80 (1997). From the results of this study, the graphite size at overheating temperatures 1350oC…

Experimental Study on Mechanical Behavior of Polypropylene-based Blends with Talc Fillers

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 6, Page # 571–576, 2020; DOI: 10.25046/aj050669
Abstract:

In this report, polymeric composites made from Polypropylene (PP) and talc powder were studied. The talc powder with different portions of 10%, 20%, 30% by weight was used to create samples. The samples were examined by the tensile test and the flexural test according to ASTM D638 and ASTM D790. The surface morphology of the…

Low Carbon Sustainable Building Material: Maximizing Slag Potentials for Improved Lime Mortar Mechanical Properties

Advances in Science, Technology and Engineering Systems Journal, Volume 5, Issue 2, Page # 786–794, 2020; DOI: 10.25046/aj050299
Abstract:

Prior to the 19th century discovery of Portland Cement (PC), Lime Based Mortar remained popular due to its flexibility, permeability and more importantly, associated low carbon emissions. However, lime’s characteristic delayed setting/hardening time, low mechanical strength, poor internal cohesion and some volumetric changes have overshadowed significance of its outstanding features particularly, flexibility, and consequently put…
