The recent boom in construction activities and the continued urban development in Kuwait have resulted in the generation of massive quantities of construction/demolition material by-products that need to be removed from construction/demolition sites in the cities to landfill areas which are limited in the country. This paper explores the possibility and benefits of utilizing by-product material...

A model of unsaturated soil-water movement using a prediction model of basic physical soil properties for calculating correlation functions was developed using VADOSE/W. The reliability of the model was assessed by comparing the results with those of a soil-column test. Coefficients of determination, R2, between the simulated and the measured daily evaporation for sand-mulch thicknesses of 0 (c...

We have developed a mulch sheet made by inflation molding of PLA, Ecoflex((R)) and modified starch, which all have different biodegradabilities. A field test of use as an agricultural mulch sheet for mandarin oranges was carried out over two years. The mechanical properties of the mulch sheet were weakened with time during the field test, but the quality of the mandarin oranges increased, a res...

The main purpose of this work is to investigate the effect benzoyl treatment on performance sugar palm/kenaf fiber-reinforced polypropylene hybrid composites. Water absorption tests were carried out confirm benzoylation toward fabricating a more hydrophobic behavior Both treated and untreated composites that have 10 wt.% fiber loading with three different ratios between palm kenaf (7:3, 5:5, 3:...

Abstract Background Various recent studies have investigated the use of traditional fibers (metallic or synthetic) as reinforcement in mortar. In times, there has been growing interest using natural cement composites. This study was conducted to assess impact date palm, doum and sisal on mechanical properties Genetic modeling chosen find shear damage at fiber-matrix interface three composites g...

Potato (Solanum tuberosum) is one of fourmajor food crops in the world. Weed control is a major component in potato production and has been accomplished using different methods, including but not limited to the use of herbicides and straw mulch. A combination of preemergence herbicide and straw mulch may improve weed control; however, no information is available for combining both methods, alon...

The effects of plastic mulch in Hawaiian pineapple culture on runoff generation and soil erosion are poorly understood and not covered in the literature. Field rainfall simulation experiments were conducted on an Oxisol commonly used in Hawaii for pineapple production. Four treatments were no cover (hereafter called bare), plastic mulch as the sole cover (plastic), pineapple crowns as the sole ...

Organic mulch can improve the moisture, chemical composition, dust, and dust suppression of soil, beautify environment. In view rapid evaporation rate serious loss soil water in tropical areas, this paper explored effect organic materials with different thickness on increase retention improvement caused by evaporation. Rubberwood sawdust (RWS), rubberwood bark (RWB), coconut fiber (CF), Mulch (...
