Abstract

Reusing recycled waste materials in buildings is gaining more and moreattention for what it offers economic, environmental, and energy benefits;and many researchers are nowadays working on producing new sustainableconstruction materials incorporating recycled wastes. In this scope, thiswork uses an experimental approach aiming at understanding the effect ofincorporating Expanded Polystyrene (EPS) beads in concrete and proposingthermally improved concrete mixtures for the production of hollow blocksin Lebanese constructions by substituting fine aggregates with recycledproducts such as EPS in order to promote their insulating properties. Threedifferent diameters of EPS beads (2 mm ~ 3 mm, 3 mm ~ 4 mm and 4 mm ~5 mm) are studied with different volumetric ratios (20%, 40%, 60% and80%) in order to investigate the effect of EPS on the thermal properties ofconcrete. The results showed that the only the percentage of incorporatedEPS beads impacted the thermal performance of the concrete mixtureswhile the EPS diameters have a negligible effect on the thermal propertiesof the concrete samples.

Impact of Polymer Coating on the Flexural Strength and Deflection Characteristics of Fiber-Reinforced Concrete Beams DOI:  https://doi.org/10.30564/jbms.v4i2.5304 Abstract Liquid polymers (LP) have become an important structural material used in the construction industry in the last decade. This paper investigates the viability of using commercially available LPs as a coating material to improve the flexural strength of fiber-modified concrete beams. The scope included preparing rectangular prism concrete beams with a concrete mixture including fly ash and fiber and coating them with four different liquid polymers at a uniform thickness following the curing process while one set of samples was maintained under the same conditions as a control group without coating. In addition, cylindrical samples were prepared to determine the compressive strength of the concrete mixture. Following the curing process in an unconfined open-air laboratory environment for another 28 days, concrete sample

Achieving Sustainable Use and Management of Water Resources for Irrigation in Nigeria DOI:  https://doi.org/10.30564/jees.v2i2.2505 Abstract Water resource is available in Nigeria to meet water demand for domestic, agricultural and industrial use. If well enhanced and protected from various source of pollution. However, less information is available on suitability of water resources for irrigation use in Nigeria. This article reviews literature of the past with regards to influence of geogenic and anthropogenic activities on water resource for irrigation purpose in Nigeria and also to explain the current state of suitability of water resource for irrigation studies in Nigeria and gaps in studies. It also summarizes future ways on water resource management and preventive measure for water resource pollution for irrigation use. Related articles were downloaded from Google scholar in water-related issues. This paper tends to review previous article on water resource in Nigeria, and its su

Soil Bunds Effect on Soil Properties under Different Topographies of the Southwest Ethiopia

Soil Bunds Effect on Soil Properties under Different Topographies of the Southwest Ethiopia Abstract Soil erosion is a major environmental problem affecting development endeavor. Physical soil and water conservation (SWC) measures such as soil bunds are implemented to mitigate soil erosion. However, information on the effects of soil bunds on soil fertility is limited. This study was aimed to evaluate soil quality in fields with soil bunds and with no soil bunds in steep, middle and lower sloping cultivated lands as well as spatial variation of soil properties in between bunds in southwest Ethiopia. About 7-15 years old bunds and nearby cultivated fields lacking bunds were assessed. From 0 cm-20 cm soil depth, a 36 soil samples were collected. Soil texture, soil organic carbon (SOC), total nitrogen (N tot ) and exchangeable potassium (K exch ) were analyzed. Soil bunds showed significantly ( p <0.0.5) greater clay but less sand than adjacent no-bund fields. In steep, middle, and low
