Experimental study of free abrasive wire sawing for multi strands wire

Wang Jinsheng,Yao Chunyan,Peng Wei,Jin Xin,Chen Shijie

Strategic Study of CAE 2012, Volume 14, Issue 11, Pages 94-98

Abstract: speed and remove the workpiece material in the free brasive wire sawing.Multi-strands wire is made by metal wires and has many grooves in the surface compared with steel wireIn this paper, optical glass K9 were cut by multi strands wire (0.25 mm) and steel wire (0.25 mm).Theresults show that multi strands wire is better than steel wire in slicing efficiency and surface roughness, but the kerf loss is wider than steel wire under the same process conditions.

The use of fine portions from construction and demolition waste for expansive soil stabilization: A review

Mgboawaji Claude UJILE; Samuel Jonah ABBEY

Frontiers of Structural and Civil Engineering 2022, Volume 16, Issue 7, Pages 803-816 doi: 10.1007/s11709-022-0835-z

Abstract: Construction and demolition waste (CDW) are the largest waste products in the world today and competes as a viable recycled additive material in place of natural aggregates. Due to the increase in compressive strength of different mix proportions of CDW, it is also considered for reuse in concrete and subbase construction. This study shows the effect of CDW in expansive soil stabilization. The chemical and mechanical properties of these materials have shown that they are capable of developing compressive strength properties for replacement of cement with significant reduction in carbon emission. The inherent compositional properties of recycled CDW compared in this review suggests that CDW have good filler properties in highly expansive soils. Mixtures of crushed brick and recycled aggregates characterised based on chemical properties of different replacement ratios suggests that CDW of good-quality aggregates reduces swell potential of expansive soils and increased mechanical strength in pavement construction.
