Eva luation of The basalt aggregates for the (in north-west area ' Jesser Al-Shogoor ') use in concrete construction works

Using different alternative materials in concrete mix, and expanding the area of using these materials, is considered very important from scientific, economic, and environmental point of view. Especially the diversity in number of used aggregates. As a result, reduction in the cost of transportation saving the environment, and improving the properties of concrete mix may occur Basalt lava, and volcanic cines are widely present in Syria, but using lava is limited because the studies about Syrian basalt were not enough. The lack of proper mills or crushers to grind basalt to be good to prepare concrete mix. As a result, the investment of using Syrian basalt in preparing concrete mix was very limited. Investigating, and classifying the basalt quarries, is needed to find out if the Syrian basalt is convenient to prepare concrete mix, or bitumen mix. The purpose of this research in to use the natural resources in different Syrian areas in better engineering,environmental,and economical ways through the improvement of engineering sides, increasing the capability of concrete structures, better investment of quarries in Syria, and to get more economical benefit with minimum cost. In this research, an experimental study was achieved to evaluate the basalt in north Syria according to international standards and codes. The composition of basalt Ore was determined by petrogrphic study, with focus on the content of olivine in basalt, and the degree of deterioration.

A Kinetic study of dissolution of Iron and Titanium from Syrian basalt at different conditions

The dissolution rate of Iron and Titanium from Syrian basalt rock was studied by hydrochloric acid, sulfuric acid, mixture of hydrochloric acid methanol, sulfuric acid methanol solutions. The effects of temperature, time of digesting and concentrations of acids have been investigated, the ratios of solid to liquid and stirring speed were constant (S/L=0.02). It has been clear that when the mixture of hydrochloric acid and methanol (100:50(V:V) HCL:CH3OH) was used, the best dissolution for both iron and titanium was obtained when we digested the rock and it took 6h at 100 ˚C where as the concentration of hydrochloric acid and methanol were [HCl]=11M, [CH3OH] =0.92M, the resulting ratios of dissolution of iron and titanium in the mentioned conditions were 75.53%, 63.19 % respectively.

Study of Palaeomagnetism and Some Magnetic and Physical Properties of Some Tertiary Igneous Rocks between Sana’a and Al-Hudyadah Region (Republic of Yemen)

Palaeomagnetism and some magnetic and physical properties (magnetic susceptibility, intensity of the Natural Remnant Magnetization (NRM), ac current electrical conductivity and density) of 136 samples from 22 sites of the Yemen Volcanic Group TKY (Tertiary and (or) Cretaceous) from igneous rock exposures along the road from Sana’a – west towards Al-Hudyadah were studied. A single population consists of seven Virtual Geomagnetic Poles (VGP), of the Upper Oligocene, was accepted and a mean at 182.81° E, 77.44° N with α95= 12.5° was calculated. The different properties were measured in order to use these properties as characteristic factors to discriminate the neighboring igneous flows. The measurement of the in situ magnetic susceptibility of 140 points, distributed on 7 sub-areas, in the region helped to calculate the mean value of the magnetic susceptibility of each sub-area, which might be used in any magnetic interpretation of aeromagnetic or magnetic anomalies. Also, the density of 132 samples were measured and a mean value of the density of each sub-area was calculated in order to be used in any future interpretation of any gravity anomaly in the area.

The Use of Magnetic Susceptibility in the Classification of Basaltic Rocks of Southern and South-Eastern Syria

The aim of this study is to use the measured values of the magnetic susceptibility in the classification of the basaltic rocks and their different differentiation degrees as an additional discrimination factor to the geochemical analyses, which were applied on the basalts of southern and southeastern Syria. So the magnetic susceptibility of ٢٠٤ specimens sampled from all the ٧ basaltic groups in Qasr Shbeeka area in addition to ٦٢ specimens sampled from three groups from outside the studied area were measured. This led to the determination of all the magnetic susceptibility ranges, their mean values and their standard deviation of the basaltic rocks in the area.

Study of the effect of the addition of the booster on the performance of the basin solar still under the climatic conditions of the city of Homs

Solar energy being one of the most promising alternatives, this because of its availability and low cost compared to other energies. The device that uses solar energy to desalinate saline water is called the solar still. The problem at the solar still is reflected in its low efficiency, with the aim of raising it. This research presents a theoretical and experimental study for single-slope and single-basin solar stills.

CLIMATE RESPONSIVE BUILDING DESIGN STRATEGIES OF VERNACULAR ARCHITECTURE IN SWAIDA CITY, SYRIA

The history of Swaida city in several civilizations was clear through architecture as if it formed a mixture of them all. Each culture had its own way of dealing with the environmental conditions, combining these design strategies accumulatively resulted in a rich architecture that deals with the environment in a very systematic way. On the other hand, the construction strategies dealt with a lot of limitation such as the lack of resources and experiences which were not available during those periods. This report describes the historical and climatical characteristics that Swaida city has, and reviews some design strategies that used to respond to climate challenges.
