Abstract The objective of the study is to evaluate properties plywood made from rubberwood veneers thermally treated at various temperatures. Rotary-peeled were 160, 170, 180, and 190 °C under 1 bar pressure. 5-ply panels produced using melamine urea formaldehyde (MUF) resin as binder. Dimensional stability, i.e., water absorption (WA) thickness swelling (TS) well mechanical assessed. results d...

The purpose of this study was to compare fluid retention of carbohydrate plus protein, a carbohydrate-only, and water following 2.5% body weight (BW) loss. Thirteen subjects dehydrated to 2.5% of BW, then ingested a CHO (6%) plus protein drink (1.5%; CP), a 6% CHO drink, or water (WA) at a volume equal to BW loss during a 3-h recovery. Fluid retention was significantly greater for CP (88 +/- 4....

The present study deals with the physical and mechanical properties of dry-formed medium density fibreboard (MDF) made from renewable biomass kenaf (Hibiscus cannabinus L.) stem as a function of adhesive level and refining conditions. Raw material was prepared by heating for 5 min at pressure levels of 6 and 8 bars. Experimental samples with a target density of 700 kgm -3 were produced with 10,...

Abstract The present study is aimed to develop a high strength concrete by using mineral admixtures of wood ash (WA), metakaolin (MK), and chemical admixture. In order check the compatibility, physical properties materials are studied. specific gravity, bulk density fineness ordinary Portland cement, have been When compare other materials, has more it implies reactivity than ash. Similarly, fin...

The scarcity of fine natural aggregates and the negative environmental impact their extraction make it necessary to find new sources for construction industry. use recycled (RA) derived from waste concrete crushing is a viable option reducing non-renewable raw material consumption. quality these lower than that aggregates. In particular, water absorption (WA) fraction RA topic constant debate d...

Plant and animal fibers are getting recognition from researchers academicians as a potential reinforcement for polymer composites due to their ecofriendly nature sustainability. In the present study, fabrication has been carried out on Jute Vetiver fiber reinforced Epoxy using hand lay-up technique with varying mass of in epoxy matrix modifier graphite which fixed by weight. The mechanical (ten...

The aim of this study was to investigate the applicability sugar beet pulp (SBP) in particleboard production as a substitute for wood material. Two variants board density, 650 kg/m3 and 550 kg/m3, containing 0%, 25% 50% SPB, were evaluated. During following features measured: modulus rupture (MOR), elasticity (MOE), thickness swelling (TS) water absorption (WA). results showed that boards up SB...

In this study, the recycled concrete aggregates and powder (RCA RCP) prepared from basaltic waste were used to replace natural aggregate (NA) cement, respectively. The NA (coarse fine) was replaced by with five percentages (0%, 20%, 40%, 60% 80%). Consequently, cement RCP four 5%, 10% 20%). Cubes 100 mm edge length for all tests. compressive tensile strengths (fcu ftu) water absorption (WA) inv...

Previous studies have shown that seawater may alter the wettability in the direction of more water-wet conditions in carbonate reservoirs. The reason for this is that ions from the salt (sulphat, magnesium, calsium, etc) can create a wettability alteration toward more water-wet conditions as salt is absorbed on the rock. In order to initiate a more systematic study of this phenomenon a 1-D math...
