Despite the attention focused on click and mortar strategies, little empirical work has directly addressed the sources of competitive advantage of this approach, nor the factors that distinguish between a successful and unsuccessful implementation. In this paper, we review theoretical work that establishes the basis for expecting synergy between e-commerce and physical presence in a market. We ...

In this study, the performance of several binary and ternary mixtures containing high-calcium fly ash other pozzolans, such as Class F silica fume, were investigated for their sulfate resistance using different sodium solutions. The mortar bars placed in a similar solution per modified ASTM C 1012/1012M (33,800 ppm SO42?) with less severe (6000 has been tested to resemble actual field duration ...

After the tide of the Internet and impact of the Internet bubbled, E-Commerce business models have moved toward the click-and-mortar business models which could improve the revenue for keeping survival. This study is to explore the relationship between the click-and-mortar model and its performance based on the innovation approach. From the innovation perspective, three dimensions of the click-...

This paper presents the experimental results of the investigation of various properties related to the durability and longterm performance of mortars made of Fly Ash blended cement, FA and Ordinary Portland cement, OPC. The properties that were investigated in an experimental program include; equilibration of specimen in different relative humidity, determination of total porosity, compressive ...

*Correspondence: Xun Yu, Department of Mechanical and Energy Engineering, University of North Texas, Denton, TX 76203, USA e-mail: [email protected] Sodium dodecyl sulfate (SDS) and sodium dodecylbenzene sulfonate (NaDDBS) were used as surfactants to disperse multi-walled carbon nanotubes (MWNT) in cement mortar and fabricate pressure-sensitive carbon nanotubes filled cement mortar composites. The...

We consider a second order elliptic problem with a heterogeneous coefficient written in mixed form. The nonoverlapping mortar domain decomposition method is efficient in parallel if the mortar interface coupling space has a restricted number of degrees of freedom. In the heterogeneous case, we define a new multiscale mortar space that incorporates purely local information from homogenization th...

Lightweight mortar is a specific type of that made by adding foaming agent. A lightweight has lot pores or cavities filled with air, which reduces the mortar’s weight. The better heat insulation than an ordinary its high porosity. There been much research and application in last few years. This review focuses on natural additive good high-temperature resistance. Many additives can be used, such...

Mixtures of mineral aggregate and modified sulfur, wherein the modified sulfur functions as a binder, are termed sulfur concretes or sulfur mortars depending on the form of the mineral aggregate. Molten sulfur reacted with olefinic additive, at 130-140 ºC, and then mixed with preheated filler and aggregates. Sulfur mortar samples were prepared by mixing 32 % molten sulfur, 10 % filler and 5...
