In this paper, Silica Fume (S.F.) be used for reinforce pozzolanic cement paste and the effect of using many weight percentages as (0%, 5%, 10%, 15%, and 20%) to lessening the concrete weight as a cement replacement in concrete mixtures on the mechanical properties was studied. High range water reducing added to decrease the water demand of the concrete, when silica fume added. Moreover, (0.025%, 0.05%, 0.1%, and 0.15%) are the proportions of polypropylene Fibers (P.P.F.) by volume, which used to improve the pervious concrete mechanical properties, physical, and mechanical properties of hardened concrete containing voids ratio, compression strength, and flexural strength and, splitting tensile strength investigated. The density of reference pervious concrete that was get through the experimental work was( 1835 Kg/m3 ) at (28) days ,it permeability coefficient (K) and voids content was( 0.324) cm/s, and (30.21%) successively, The results shown important increase in compression, splitting tensile and flexural strengths of pervious concrete containing silica fume and (P.P.F.) comparison with reference pervious concrete. The mixture of (10%) of (SF) and (0.1%) of (P.P.F.) gave optimum increased in the compressive, flexural, and splitting tensile strengths compared with the reference mix and the results (47.8%, 29.21%, and 24.41%) respectively.

The Kaolinite soil is considered as a problematic soil due to its low strength with high water content, low density and low permeability. So, there are attempts to improve the engineering properties of this type of soil by mixing it with different additives. In this study the Date seeds powder was used in two forms, first: as a powder (DSP) and mixed with the Kaolin soil at different percentages by weight (3%, 5%, 7% and 10%), and second, the powder was burned at 450 O C for 4 hours in furnace (DSPB) then mixed with Kaolin soil at different percentages by weight (3%, 5%, 7%, and 10%). The results show an increase of 755% in the strength of the Kaolinite soils at 5% DSPB as compared to the origin strength when testing in unconfined compressive strength test UCS. Also, the results show a decrease in plasticity index for all mixture percentages in DSPB by 26.2% using 10%DSPB. Curing time results show high percent of increase in strength from 170 to 310 kN/m 2 for 0 to 28 days respectively, this increase equal to 1386% from strength of reference soil.

In order to evaluate the quality of groundwater for drinking suitability purposes, a total of 27 groundwater samples from wells in southwest of Basrah city have been analyzed for various geochemical parameters. The aim of this research was to find the physicochemical quality of ground water in the southwest of Basrah. The results show that the quality of groundwater regarding the physical and chemical parameters of southern Basrah is unsuitable for drinking purposes. The total hardness (TH) was very high and it was in the ranged (740-6950) mg/l, also the electrical conductivity (EC) was very high and ranged (1720- 18030) μS/cm, while the World Health Organization (WHO) recommends a value less than 100 mg/l for (TH) and 750µs/cm for (EC). According to the international and national standards the allowable concentration of total dissolved solids (TDS) should not exceed 500 mg/l, while the groundwater samples of the study area shows a range of (1200-10790) mg/l, therefore it is considered very high. Moreover, the other physicochemical properties of groundwater were analyzed and compared with those of drinking water standards recommended by the WHO. Groundwater for irrigation has been studied by using the rating of water samples in relation to salinity and sodium hazard graph. As a result of the study, only one sample was accepted for irrigation.

This study investigated (experimentally and analytically) the influence of mortar compressive strength (37.4, 48.3 and 60.1 MPa) and the number of wire mish layer in web and bottom flange on the shear behavior of ferrocement slender box beams. To achieve these targets, 12 ferrocement box beams with shear span to effective depth ratio(a/d) of 2.8 (slender beams) are equipped, tested and assessed, all beams having cross section of 300*175 mm, length of 2000 mm and hollow core of 180*115 mm. The tested beams were divided into four groups, each group consists of three beams depending on compressive strength value, the first group was without wire mish, the second group was with one layer of wire mish in web and bottom flange, the third group was two layers of wire mish in web and one in bottom flange and the fourth group was with two layers of wire mish in web and bottom flange. As well as ANSYS-11 program was used to analyze these beams by nonlinear finite element method. Test results showed that, the first cracking and ultimate loads increases as the wire mish layers in web and bottom flange increases, the deflection of the tested beams decreases with increasing mortar compressive strength and wire mish layers in web and bottom flange, the finite element model gives good agreement with the experimental results within 9%.
