The discharge of untreated effluents into nearby water bodies or nearby land is not only aesthetically displeasing, but it also restricts light penetration, thus upsetting biological processes within a stream. In addition, many dyes are toxic to some organisms causing direct destruction of aquatic communities. Some dyes can cause allergic dermatitis, skin irrigation, cancer and mutation in man....

As a result of intrastratal and interlayer flows produced water varying intensity, 25% oil gas wells are water-encroached in the world. Due to behind casing flow during operation generally reduces field's development efficiency. In study, 1-6% (weight) polyethylene polyamine (PEPA) was added which cement mixture will be prepared. The temperature dependence beginning end setting time obtained mo...

This research assesses the viability of utilizing construction and demolition waste (CDW) for production environmentally-friendly bricks. The methodology employed in this study consists three main components: An analytical evaluative investigation CDW, selection appropriate materials, determination suitable proportions. experimental groups were prepared using a volumetric approach, namely Type ...

The feasibility of recycling carbon dioxide into concretes through their curing processes was investigated. The CO2 uptake capacities of four commonly used concrete building products: masonry block, paving stone, cement board and fiberboard, were evaluated. It was found that, based on the cement content used in the product, the uptake capacities of the four products ranged from 9.8% to 18.9% wh...

This paper presents the results of an experimental investigation carried out to evaluate the shrinkage of High Strength Concrete. High Strength Concrete is made by partially replacement of cement by flyash and silica fume. The shrinkage of High Strength Concrete has been studied using the different types of coarse and fine aggregates i.e. Sandstone and Granite of 12.5 mm size and Yamuna and Bad...

This paper shows the use of dimension stone waste in manufacture soil-cement bricks. Initially, a sample soil was analyzed for mineralogical composition, particle size distribution (classifying it proportion silt, sand, and clay), physical performance by plasticity (Atterberg limits specified standard NBR 7180). A series soil/waste/cement mixtures were prepared with contents up to 90% wt.% wast...

This research deals with production of light weight aggregate concrete by using clayey stone aggregate, normal material (cement , sand) and some mineral admixtures (fly ash steel fiber ). Many trial mix were doing these weighing ratio others volumetric . We get (LWAC) 24.92 N/ mm2 compressive strength we improved mechanical properties adding same percentage fly (0.5 ,1 ,1.5) % each other as a c...

Modern requirements for the quality of constructural building materials determine need development highly efficient durable composites based on cement binder. Obtaining such implies use additives and modifiers increasing strength characteristics concrete reduce production defects by stabilizing structure properties products. In this research, produced private company limited shares "NP CMID" (S...
