Iron Filings (IF) and brick powder (BP) waste materials taken from steel workshops and factories ... more Iron Filings (IF) and brick powder (BP) waste materials taken from steel workshops and factories and demolition of buildings respectively .create serious environmental problems ,so the main aim of this paper is to estimate the potency of employing the mixing of waste materials (Iron Filings and brick-powder) altogether as partly replace of cement and the fine-aggregate respectively in the composition of concrete which were mixed with a ratio of (1:2:4) and (W/C) ratio equal to (0.45). In this study the cement has been replaced by Iron Filings in the proportion of ( 10%, 20%,30 %and 40%) and fine aggregate replaced by waste brick powder in the proportion of (0%,5%,10%, and 15%) by weight of concrete mix simultaneously. In this paper, the split tensile strength , the compressive strength and flexural strength of the concretes mixtures were specified. The main results of this paper appeared that the (cement and sand) can be partially replaced by ( Iron Filings and brick-powder) in the concrete mixture and it has achieved the optimum percentage of replacement by (30%IF+10%BP). So the utilization of solid waste is required in an attempt to equilibrate between the construction request and environmental sustainability and as well as saving landfill space.

In this study the cement has been replaced by marble dust waste in the proportion of (0%,5%, 10%, 15%, 20%, 25%) and fine aggregate replaced by waste brick powder in the proportion of (0%,5%,10%, 15%,20%,25%) by weight of concrete mix simultaneously. In this paper the (compressive , flexural and split tensile) strength of the concretes mixtures were specified. The main results of this paper appeared that the (cement and sand) can be partially replaced by(marble-dust and brick-powder) in the concrete mixture and it has achieved the optimum percentage of replacement by (20)%. So that utilization of construction waste is required in an attempt to equilibrium between the construction request and environmental sustainability.

However, the construction industry’s insatiable need for building supplies has led to the widespread exploitation of natural resources like river sand and stone. However, one of the most pressing problems in the construction industry and others nowadays is excessive waste and byproducts. Promoting ecological control and the goal of sustainable progress has put environmental pressure on all businesses, including construction, to embrace eco-friendly practices. Environmentalists’ concerns about the dangers posed by the widespread use of natural resources in building construction are growing. In some instances, construction debris may be harmful to the environment. Global building growth and redevelopment plans have worsened demolition in the construction industry. The demand for construction materials is increasing yearly due to urbanism, but their costs are rising simultaneously. Using industrial waste like polymers and rubbers and natural waste like olive stones and pumice stones to replace cement, fine aggregate, and coarse aggregate to reduce building costs conserves natural resources from exhaustion and protects the environment from waste impact and risks. The current research shows how waste can be used to replace materials on construction sites and the impact of the properties of these materials on the quality of concrete.

Polystyrene grains shape samples were irradiated using the radioactive element Cesium- 137 with (9 µci) activity for 10, 20, and 30 minutes. The viscosity of the polymer solution depends on the concentration and size (i.e. molecular weight) of the dissolved polymer. Experimental data showed that the radiation dose affected the value of viscosity (shear, relative, specific, and reduced). The viscosity value significantly reduced at 10 min radiation dose and when increasing the dose, the viscosity value increased up to 30 minutes. Deterioration of the polymer structure was recorded for a 10 minutes radiation dose. With the increase of radiation time, which reached 30 minutes, cross-linking was performed due to the substance gaining additional doses of radiation. The m...
