Perbandingan Kuat Tekan Beton Ringan Dengan Metoda Rancang-campur Aci Dan Dreux-corrise [PDF]
, 2011 Lightweight concrete is one of solving problems to deficiency or loss that is about the size of the dead load weight of the concrete itself. Generally, lightweight concrete has the same mix-design with normal concrete, except that coarse aggregate in ...

Advanced Engineering Materials, EarlyView.Laser surface texturing significantly improves the corrosion resistance and mechanical strength of 3D‐printed iron polylactic acid (Ir‐PLA) for marine applications. Optimal laser parameters reduce corrosion by 80% and enhance tensile strength by 25% and ductility by 15%.

Dynamic Precipitation during High‐Pressure Torsion of a Magnesium–Manganese Alloy
Advanced Engineering Materials, EarlyView.An ultrafine‐grained alloy is produced by high‐pressure torsion of solutionized Mg–1.35 wt% Mn. Precipitation of nanometer‐scale Mn particles during deformation provides pinning sites. This prevents the formation of a bimodal grain structure and results in a finer grain size than for pure Mg.

Recycling of melamine formaldehyde waste as fine aggregate in lightweight concrete [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2018 Lightweight concrete production using melamine formaldehyde (MF) waste as fine aggregate by partially replacing river sand was investigated. Two forms of MF waste, granules and waste powder, were employed to produce the concrete of 1,000 and 1,300 kg ...

The influence of granulation on lightweight aggregate on early autogenous shrinkage of high strength concrete [PDF]
, 2013 Early autogenous shrinkage of high strength concretes is relatively large. It can be reduced by using internal water reservoirs. Lightweight aggregate was used for internal water reservoir.

Fibre reinforced lightweight aggregates [PDF]
Journal of the European Ceramic Society, 2014 Abstract Carbon steel fibre reinforced lightweight aggregates (LWA) were produced in a pilot scale rotary kiln. Narrow size fractions as well as not-sieved (as received) material were investigated according to European standards with a main focus on strength and density and compared to a reference material without fibres. Depending on the size of the
