This research aimed to produce concrete that will decrease disadvantages of portland concrete and resolve it. Mixture of Silica fume with concrete in this paper shows that the strength and hardness are increased. In this research the main gools is to compare the deference of compressive strength between standred concrete and concrete with silica fu...

Worldwide, a high proportion of generated total solid waste is Construction and Demolition Waste (CDW), the majority of which ends up in landfills. It has been proposed that this type of waste has potential for being recycled and reused as aggregates in production of fresh concrete, particularly for basic usage. The present study explores how feasi...

Concrete demonstrating high durability, lightweight, and high strength is demanded by a growing number of building projects. Concrete with these properties was achieved in Jordan by employing widespread local raw materials to make Lightweight High-Performance Polymer Concrete (LHPPC). The present study sought to assess the impact of new concrete mi...

It is an established fact that when roads are planned and constructed, consideration needs to be given to ensuring the strength of the road surface. It is, however, also the case that when an existing road is being rebuilt or is under maintenance, its base may need to be fortified to increase the road's vehicle-carrying capacity. The base may, for...

In Jordan, the unprecedented proliferation of building projects is anticipated to increase the potable water demand in the construction manufacturing. In the present work, secondary treated wastewater (STW) and potable water (PW) were used in the production of concrete mixes, which were subjected to testing after 3 to 28 days of curing to determine...

Article
Full-text available
This study aimed at evaluating water quality of groundwater wells (GWWs) in Wadi Shati, Libya, and assessing its suitability for drinking. Water samples were collected from 17 GWWs and subjected to laboratory testing for 24 physical and chemical water quality parameters (WQPs). Analysis uncovered that the recorded values of 11 WQPs were consistent...

Corrosion of steel in reinforced concrete causes severe damage in durability as weakness support of reinforced elements. We investigate impacts of cement fraction and curing method on corrosion progression. Corrosion level is evaluated by measuring carbonation penetration and electrical conductivity in concrete plots as indicators of corrosion. Two...

Groundwater in the Murzeq Basin (Libya) is a major source of water supply for all human activities, especially drinking water, and the presence of groundwater in the geological formations bearing it in the layers of the earth is one of the primary factors that control the quality and quantity of dissolved salts. Sulfur ores in the entire Wadi Al Sh...
Article

Hot Mix Asphalt (HMA) design is one of the most important types of pavement used in highway construction. This research provided a hot mixture design method modifying with Crump Rubber Scrap Tire (CR) in order to develop and determining the optimum additive for hot mix asphalt design. All tests conducted to the raw material including specific gravi...

Concrete is one of the essential elements that used in different types of construction this days, but it has many problems when interacts with environmental elements such as water, air, temperature, dust and humidity. Also concrete made with Portland cement has certain characteristics: it is relatively strong in compression but weak in tension and...

Soil stabilization is a process whereby increased strength and stability of the soil is attained mainly by mechanical or chemical means. The most common improvements achieved through stabilization include better soil gradation, reduction of plasticity index or swelling potential, increase in durability and strength. The aim of this research is to i...

An alternative use of a specific type of cement for a particular purpose, usually we can change some properties of available cement by using the appropriate additions, with some negative side effects in some cases. In this research have been suggested values of calcium chloride(CaCl 2) additions for use in concrete admixtures as an agent factor in...

Phosphorus is an essential nutrient. In spite of its wide distribution in nature, P is a limited resource and it is deficient in most soils. This study is aimed to evaluate availability of phosphorus in desert soil with a sandy texture, treated with organic waste (dung of sheep) at rates of different additions (amount applied at 30, 60, 90 & 120 to...

Agricultural drainage water in Ashkada-Barak agricultural project is a major source of wasted water, which amount to about 35 million liters per day. This huge sum of wasted water cause a formation of pools around the area and therefore a lot of environmental problems such as the proliferation of mosquitoes, and other health problems, while it can...

Nitrogen (N) is the nutrient absorbed in highest amount by plant, and this element most frequently needed by crops. The present study aimed to determine the mineralization rate of organic nitrogen in sandy soil abundantly available in Wadi- Ashati region of Libyan Arab Jamahiriya, during different interval time by adding different amount of organic...
