Sustainability is important to the well-being of our planet, continued growth of a society, and human development. Concrete is one of the most widely used construction materials in the world. However, the production of portland cement, an essential constituent of concrete, leads to the release of significant amount of CO2, a greenhouse gas (GHG); production of one ton of portland cement produce...

In terms of absolute consumption, the cement industry occupies a front position in the ranks of energy consumed industries. The total energy costs (thermal and electrical) make up about 30 to 40 percent of the total production costs of cement. This is why efficient energy utilization has always been a matter of priority in the cement industry. Cement manufactures requires very high temperatures...

A Portland cement plaster wall system has many positive features, but one of the physical properties that it does not possess is flexural strength. It is because of the inability of the Portland cement plaster membrane to bend or flex that glass fiber strands were used in Portland cementbased plaster. There are various types of synthetic fibers on the market that will provide flexural strength ...

For a long time collaboration between Universities and industry has been existed, but the rapid increase of global knowledge has strengthened the demand for strategic relationships that go beyond the conventional funding of research projects. The role of the university‟s research should be developed in the coming centuries to play an important role in industrial and in turn economic growth. To ...

BACKGROUND AND PURPOSE The long-term success of cemented total hip arthroplasty (THA) has been well established. Improved outcomes, both radiographically and clinically, have resulted mainly from advances in stem design and improvements in operating techniques. However, there is concern about the durability of bone cement in vivo. We evaluated the physical and chemical properties of CMW1 bone c...

Vol. 8 No. 4 1996 The DIGITAL AlphaServer 4100 system is a symmetric multiprocessing (SMP) midrange server that supports up to four Alpha 21164 microprocessors. A single Alpha 21164 CPU chip may simultaneously issue multiple external accesses to main memory. The AlphaServer 4100 memory interconnect was designed to maximize this multiple-issue feature of the Alpha 21164 CPU chip and to take adva...

objective: the present study was hypothesized to investigate the beneficial effects of fresh, aged, and cooked garlic extracts on blood glucose and memory of diabetic rats induced by streptozocine (stz). material and methods: diabetes was induced by an intraperitoneal injection of stz (60 mg/kg body weight). an oral dose of 1000 mg/kg of each garlic extract was given daily for 4 weeks after dia...

Optimizing and decreasing the fuel consumption and as a result preserving the national financial resources are so important purposes in the resistive economic which has been becoming so vital during previous years due to the implementation of sanctions against Iran. Using the alternative fuels stemming from municipal waste and using them in the energy industry of cement can be some suitable sol...

supply chain management as a vital challenge to the cement industry and developing infrastructure as a whole has been posed by scholars. this research is an attempt to investigate larg supply chain management as a comprehensive approach to consider simultaneously four basic relevant strategies namely lean, agile, resilience and green. using a survey methodology and gathering data from twenty on...

i ntroduction: many of highly-alkaline dental materials have some adverse effects on physical properties of dentin. as basic substances, mineral trioxide aggregate (mta), calcium hydroxide (ch) and the new endodontic material, calcium-enriched mixture (cem) cement, may adversely affect dentin. the purpose of this in vitro study was to evaluate the effect of long-term application of cem cement, ...
