Paper ID	75hk9
Keywords	Deflection, Strain, Recycled Concrete Aggregates, Numerical Modeling, Regression Analysis, Green Concrete, Long-Term Loading, Sustained Loading.
Abstract	Read More... Numerical modeling is a time saving and cost-effective alternate of experimental evaluation of structural members. On the other hand, green concrete being of the day is active area of research. Therefore, this research paper presents the numerical modeling of RC green concrete beams under sustained loading. The green concrete was produced using 50% replacement of natural coarse aggregates with demolished old concrete. Multi-variable regression analysis was adopted to predict the numerical equations for long-term deflection and strain from the experimental data of the parameters due to 6-, 9- and 12-month long term loading. Three software NCSS, MATLAB and Microsoft EXCEL were used for the purpose. To check and validate the developed equations six beams were cast using 50% replacement of natural coarse aggregates. Fifty percent of the beams were tested for each 2- and 3-month sustained loading. The obtained results were compared with the results from numerical equations. It is observed that the numerical results are in good agreement with experimental observations with maximum of 10.34% error. Therefore, the numerical equations for deflection and strain presented in this article can be used to estimate the parameters of RC green concrete beams due to long-term sustained loading.

Title	Assessment of Cement Ternary Blends with Different Additives & Local Pakistani Clay in Cement Mortar
Paper ID	QJdyg
Keywords	Multi wall carbon Nano tubes (MWCNT),Local calcined clay (LCC),lime (L),bagasse ash ( BA)
Abstract	Read More... This paper is about the use of clay and how the strength reduction can be minimized as the addition of clay decreases the compressive strength in cement composite. The Compressive strength is an important parameter for civil engineering construction and cannot be ignored thus different technique are used to minimize the strength reduction in cement composite with the aim that maximum clay (25 %) can be used as pozzolana .Three different materials, Lime (4.5%), bagasse ash (7.5 %) and Multi wall carbon Nano tubes (MWCNT) (0.0150%) are used along with clay content (21.5 %, 18.5 % & 24.98%) respectively in cement composite (mortar). The entire ternary blends are assessed for dry density, water absorption, Workability and Compressive strength. The results of all evaluated parameters confirmed that clay has all the potential to be used as replacement material for cement in construction projects.

Title	Migration and Enterocutaneous Fistula Formation Risk After Composite Mesh Repair in Incisional Hernias: Report of two cases
Paper ID	htmRH
Keywords	enterocutaneous fistula, incisional hernia, intestinal obstruction, mesh complication, mesh migration
Abstract	Read More... An incisional hernia is one of the most common complications of abdominal surgery. The incidence of an incisional hernia is about and the recurrence rates are reported as %-40. Meshes are commonly used to minimize the recurrence of hernia repair of all kind. Polypropylene mesh is cheaper than composite mesh and this is the reason of why it is the mostly preferred type of mesh. The type of mesh does not alter the type of complications and complications may occur even if years passed. Here we describe two cases of enterocutaneous fistula due to late migration of a composite dual mesh, 7 years and 4 years after incisional hernia repair, respectively.
