Leca lightweight particles are used for structural and semi structural concrete in different countries. In Iran it is usually used as Mass lightweight concrete, blokes and partitions. In this research an experimental work carried out using Leca concrete to assess its physical and mechanical properties and possibility of constructing high strength lightweight concrete to use as structural elemen...
Hybrid Concrete focused on the development of buildings, highways, and other structures of civil engineering. In the current study, various mix combinations have been prepared and tested with different percentages of super-plasticizer at different levels of water reduction for obtaining the optimum mix. Further, study on different properties of hybrid concrete and replacement of ordinary portla...
this research paper presents the use of wasteful supplementary cementitious materials like fly ash and silica fume to conserve the cement used in concrete. the cement industry is one of the major producers of greenhouse gases and an energy user. in this study, portland cement was used as a basic cementitious material. fly ash and silica fume were used as the cement replacements by weight. the r...

Abstract In the construction sector, non-renewable world resource of sand is largely used to produce mortar and concrete. It has been estimated that over 10 billion tons have produced, with 1.2 in concrete last decade, which leads a progressive reduction available materials environmental impacts. Since desert resources are abundant arid region Adrar (Southern Algeria), it would be viable use de...
The plasticizer di(2-ethylhexyl)phthalate (DEHP) used in peritoneal dialysate bags is known to dissolve into the solution, even though the quantity is small. Long-term exposure of the peritoneum to DEHP could be a cause of peritoneal deterioration. Although some papers have been published about DEHP toxicity to the peritoneum, acute DEHP toxicity is not fully understood to date. We therefore co...
there has been a renewed interest in edible films made of renewable and natural polymers such as protein, polysaccharide and lipids. natural polymers derived from natural sources like food protein, offer the greatest opportunities because of their biodegradability and their ability to supplement nutritional value of foods. faba bean is a valuable source of protein and is cultivated in large qua...
The objective of this research work was to design, develop and optimize the self micro-emulsifying drug delivery system (SMEDDS) of Felodipine (FL) filled in hard gelatine capsule coated with polymer in order to achieve rapid drug release after a desired time lag in the management of hypertension. Microemulsion is composed of a FL, Lauroglycol FCC, Transcutol P and Cremophor EL. The optimum sur...
