There has been continuous demand for materials with higher compressive strength for various civil engineering applications. Reactive powder concrete (RPC) has been developed to overcome the weakness of most high strength concrete available with compressive strength in the range of 60-100 MPa. RPC was developed from a special combination of constituent materials such as Portland cement, silica fume, quartz flour, fine silica sand, high-range water-reducer, water and steel fibers wherein attempts have been made to remove the coarse aggregate particles to make a very strong mortar with a very low water cement ratio..........

Statistical process control (SPC) is one of the important approaches used in quality management. SPC can be applied in plants to obtain good quality and high standard products that have become very popular in many industries. Fuzzy process capability analysis by using X-R control charts gives more realistic results, developed with fuzzy theory. Fuzzy control charts are more sensitive than SPC. Therefore, fuzzy control charts lead to producing better-quality products. In this study, total color difference parameter (ΔE) was studied using fuzzy observation on a calcite grinding plant products................

Groundwater is a better resource for water requirements, its protection and management is vital for human evolution and ecological diversity. Agricultural and industrial activities have contributed to the degradation of the quality of Berrechid groundwater. The aim of this study is to evaluate and map the vulnerability of the Berrechid aquifer using the DRASTIC and SINTACS models and to compare between them. The application of this methodology requires a GIS synthesizing a mass of data (geological, hydrogeological, Geophysics, etc.), is a real decision-making tool for water resources managers in the Chaouia region................

The aim of this research paper is to compare and analyze the effect of temperature on the octane number of reformate produced from heavy treated Naphtha of Nigerian crude during catalytic reforming. The continuous catalyst regeneration catalytic reforming process was simulated using Aspen Hysyscatalytic reformer template configured with four beds reactor.Treated heavy Napthene from Bonga Crude and Bonny Crude were used as feed for the process. It was observed that an increase in temperature lead to an increase in the octane number of reformateproduced as the values of Research Octane Number (RON) and Motor Octane Number (MON) were seen to increase from 79 to 94 and 67to 78 respectively............
