The influence of a chloride-ion adsorption agent (Cl agent in short), composed of zeolite, calcium aluminate hydrate and calcium nitrite, on the ingress of chloride ions into concrete and mortar has been experimentally studied. The permeability of concrete was measured, and the chloride ion content in mortar was tested. The experimental results reveal that the Cl agent could adsorb chloride ion...

Foamed mortar with a density of 1300 kg/m³ was prepared. In the initial laboratory trials, water-to-cement (w/c) ratios ranging from 0.54 to 0.64 were tested to determine the optimal value for foamed mortar corresponding to the highest compressive strength without compromising its fresh state properties. With the obtained optimal w/c ratio of 0.56, two types of foamed mortar were prepared, name...

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 ...

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...

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...

The impact of climate on cultural heritage surfaces leads to several damage processes and the protection and the preservation of works of art is a challenge for conservation scientists and restorers. Traditional and innovative products are used in consolidating treatments in order to reduce the effects of the interaction environment-materials. The EC NANOMATCH Project aims at the development of...
