Properties of Cement and Mortar Incorporating Marble Dust and Crushed Brick
Blended cements based on the partial replacement of Portland cement clinker (PC) by wastes have been the subject of many investigations in recent years. The use of the replacement materials offer cost reduction, energy savings, arguably superior products, and fewer hazards in the environment. These materials participate in the hydraulic reactions, contributing significantly to the composition a...

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
15 صفحه اولPhysical and mechanical evaluation of artificial marble produced with dolomitic marble residue processed by diamond-plated bladed gang-saws
The production of artificial stone from the agglutination of the epoxy resin fine waste can be a viable alternative from technical, economic and ecological points of views. The residue derives from the dolomitic marble produced by diamond-plated bladed gang-saws and it is usually discarded. With this new application, there is value added to the residue, reducing the consequent environmental imp...
متن کاملEffect of cement dust exposure on phagocytic function of polymorphonuclear neutrophils in cement mill workers.
OBJECTIVES Exposure to cement dust can cause various occupational health problems due to its increasing incidence and long-term complications. However, the influence of cement dust on phagocytic function of polymorphonuclear neutrophils (PMNs), has not as yet been investigated. Therefore, the aim of the study was to measure the phagocytic activity of PMNs by assessing chemilumiscence (CL) respo...
متن کاملThe Effect of Cement Dust Exposure on Hematological and Cytogenetic Studies of Cement Workers
The study measured haematological and cytogentic parameters in workers occupationally exposed to cement dust in order to test the hypothesis that cement dust exposure may perturb these functions. Assessments of haematological, and cytogentic were performed in 30 workers occupationally exposed to cement dust and 30 matched unexposed controls. The RBC level has no significant change and WBC level...
