A Research on using Geo-polymer Mortar as Repair Mortar

"Bricks-and-mortar" vs. "clicks-and-mortar": An equilibrium analysis

The Internet has provided traditional retailers a new means with which to serve customers. Consequently, many ‘‘bricks-and-mortar’’ retailers have transformed to ‘‘clicks-and-mortar’’ by incorporating Internet sales. Examples of companies making such a transition include Best Buy, Wal-Mart, Barnes & Noble, etc. Despite the increasing prevalence of this practice, several fundamental questions re...

Mechanical Properties of Polymer Mortar Containing Pet Waste Aggregates

Non-biodegradable plastic aggregates made of polyethylene terephthalate (PET) waste from beverage containers are used as partial replacement of natural aggregates in mortar. Various weight fractions of sand 5%, 10%, 15% and 20% are replaced by the same weight of plastic. This paper investigates the mechanical properties of the obtained composites. The main results of this study show the feasibi...

Interior superconvergence in mortar and non-mortar mixed finite element methods on non-matching grids

We establish interior velocity superconvergence estimates for mixed finite element approximations of second order elliptic problems on non-matching rectangular and quadrilateral grids. Both mortar and non-mortar methods for imposing the interface conditions are considered. In both cases it is shown that a discrete L2-error in the velocity in a compactly contained subdomain away from the interfa...

Mortar Boundary Elements

We establish a mortar boundary element scheme for hypersingular boundary integral equations representing elliptic boundary value problems in three dimensions. We prove almost quasi-optimal convergence of the scheme in broken Sobolev norms of order 1/2. Sub-domain decompositions can be geometrically non-conforming and meshes must be quasi-uniform only on sub-domains. Numerical results confirm th...
