STUDY ON CONTROLLED LOW-STRENGTH MATERIALS USING ULTRA-RAPID-HARDENING CEMENT AND STONE SLUDGE FOR BACKFILL AND SUBBASE APPLICATION IN ROAD EXCAVATION AND RESTORATION WORK

A significant amount of stone sludge is generated as a by-product during the production of crushed stone aggregate, and most of it is disposed of in landfill as waste.In order to recycle this stone sludge, this study evaluated a controlled low-strength material (CLSM) using ultra-rapid-hardening cement and stone sludge for application as backfill a

This paper proposes a new control design approach for industrial wastewater treatment where its logic control is verifiable.In iphone xr price calgary this research, a treatment control design in a lab-scale was controlled by a microcontroller circuit.The developed system combined anaerobic digestion, aeration and filtration process.Its logic contr

Plants possess regulatory mechanisms that allow them to flower under conditions that maximize reproductive success.Selection of natural variants affecting those mechanisms has been critical in agriculture to modulate the flowering response of crops to specific environments and to increase yield.In the temperate cereals, wheat and barley, the photop
