Effect of Alternate Drying Techniques on Cross-Laminated Timber after Exposure to Free-Water Wetting

چکیده
Cross-laminated timber (CLT) panels are commonly used in mass-timber multistorey constructions due to their prefabrication, construction flexibility, environmental credentials and weight-to-strength ratio advantages compared competing building materials. However, the long-term durability service life of these mass require further understanding performance when exposed free water. Wetting drying trials were conducted by exposing Radiata pine (Pinus radiata) CLT sections either water (pooling on a single surface) or submerged (all directions exposed) saturation, followed ambient fan drying. The pooling only reached MC above FSP up 40 mm panel depth. For panels, values fibre saturation point (FSP) at depths 30 penetration both faces. When comparing fan-drying over same time period, less uniform profile was observed for drying, whereas fan-dried fell below faster with more consistent profile. A complementary study standalone 3.0 × m room, where room wetted during simulated pipe burst event. moisture monitoring wall floor showed that an reduction from excess 40% 20% could be than 96 h panels’ surface; however, middle dried slower surface sections. structure required longer tested closed (overlaps connected faces) lower rate airflow. highlighted product reaching maintaining higher points need applied minimise decay development. Further is recommended investigate effects (connected duration needed semi-finished finished buildings.

Standardization of alternate wetting and drying (AWD) method of water management in low land rice (Oryza sativa (L.))
Alternate wettting and drying (AWD) systems save water compared with continuoussubmergence (CS) irrigation. However, the reported effect on yield varies widely and detailedcharacterizations of the hydrological conditions of AWD experiments are often lacking so thatgeneralizations are difficult to make. We compared the effects of AWD and CS on crop andwater productivity in rice in the field expe...

One of the technology options that can help farmers cope with water scarcity at the field level is alternate wetting and drying (AWD). Limited information is available on the varietal responses to nitrogen, AWD, and their interactions. Field experiments were conducted at the International Rice Research Institute (IRRI) farm in 2009 dry season (DS), 2009 wet season (WS), and 2010 DS to determine...

A field experiment was conducted at the Bangladesh Agricultural University (BAU) to find out possible effects of alternate wetting and drying irrigation (AWDI) on the yield, water use and water use efficiency (WUE) of Boro rice. The experimental layout was furnitured using split-plot design (SPD) with two modern varieties (MV) of rice viz. BRRIdhan 28 and BRRIdhan 29, which received four irriga...
