Most of the construction materials research now concerns on investigation of construction materials that is locally produced at a rate and cost compatible with the pace of construction. The present paper is concerned with investigation of fresh and hardened properties of self-compacting concrete (SCC) produced from local available materials in JORDAN. The produced SCC contains the local stone cut waste powder which is called Al-KHAMKHA in JORDAN with different replacement of (0%, 10%, and 25%) of fine silica aggregate; the study also investigates the effects of SP33 super plasticizer which is used by different doses (1%, 1.5% and 2%) for cement. The slump flow and the compressive strength of SCC were studied and the experimental results indicate the possibility of using Al-KHAMKHA in the production of SCC as the results showed that the compressive strength of the SCC with 10 % replacement by al-khamkha together with 1% SP33 super plasticizer was higher compared to pure SCC without al-khamkha; the results also showed that as al-khamkha content increased the slump flow decreased.

Many researchers have been interested in studying the effect of adding local natural materials or construction waste on the properties of poor subgrade soil. However, changes in size and strength of expansive soils can cause extensive damage to the geotechnical infrastructure. This damage is often repeatable and latent in the long term, and is a critical issue in highway subgrade engineering. This paper examines the effect of adding both Fine Silica Sand (FSS) and Granite Cutting Powder Waste (GPW) materials on the welling characteristics of expansive soils. Atterberg limits, free swell index, and rate of swell of the mixtures were used as a key to assess properties of a group of expansive soil samples after adding different percentages of the mentioned materials. The rates of additions were 10%, 20%, 30%, 40%, 50%, 60 and 70% of the weight of the soil samples. The test results showed that FSS and GPW significantly affect the expansive soil properties. However, adding 70% of both FSS and GPW reduced the swelling index from 58.3% to 6.6% and from 58.3% to 11% after 7 days of curing, respectively. This study suggests that the Fine Silica Sand and Granite Powder Waste can be used as stabilizers for expansive highly plastic soils.

One of this theoretical study, parameters that affecting the ultimate load capacity of the axially loaded column are studied. The parameters such as compressive strength of concrete and steel reinforcement ratio.  Throughout study a different value of each factor will be assumed. Then the nominal load-carrying capacity of axially loaded column was calculated for these different factors parameters according using the simplified methods provided in (ACI-318- 14) building code requirement for structural concrete and Prokon Program. It is observed that increasing the compressive strength of concrete result in improving the ultimate load capacity. Using compressive strength of concrete more than 40MPa which results in increasing of (Pu) from (2362kN) to(5918KN) . On other hand The total area of longitudinal reinforcement bars (AST), and the gross area of concrete section (Ag) have a significant effects also on increasing of (Pu) value but not as (Fcʹ).  

Transportation in porous media is a very interested topic, which has attracted many researchers from various disciplines especially for water resources. This research covers materials related to details related to the study of groundwater transport across layers. The research results are used to understand and define the problems of porous media and to produce knowledge of the theoretical and practical aspects of transporting porous media for different purposes of water and gases, including carrying out laboratory and actual volume tests, interpreting the model with the help of test and then predicting and simulating various porous media processes under different pressures. Seismic tests are conducted to find out the soil layer under the examination area and how water and gases are transferred. The work study to the investigate the critical factors in the design and implementation of the Underground Storage and Recovery (ASR) program? To reduce evaporation from exposed dams. And to analyze the water footprint in Jordan and Reducing the artificial ground subterranean projects in Jordan. Aesthetic plastic surgery in Jordan.

In many buildings, the roof is a major element that gives the building its distinctive profile .The main purpose of a roof is to protect the building or the house in all types of weather with a minimum of maintenance .a roof must be strong to with stand snow and wind loads. Another consideration is appearance .a roof should add to the attractiveness of the building roof styles are used to create different architectural effects. This paper reports a study on flat roof systems include the layers of structural elements of the roof, types of finish used, flashing, roof edging, drainage, and other details associated with the roof.   © 2018 JASET, International Scholars and Researchers Association
