The concrete structure will be seriously eroded in a sewage environment, causing substantial economic losses. Therefore, it is of great significance to repair the existing corrosion structure. In order quickly restore mechanical properties and enhance durability performance structures, this paper develops new composite high-durability mortar by adding polypropylene fibers, basalt fibers imperme...

Over the past decades, a major part of building infrastructure has aged and is now in need repair. In order to ease repair backlog be able distinguish between urgent long-term needs, it advisable install monitoring system structure. This is, among others, often based on periodical strain or deformation measurements, as they provide direct indication effect external loads structure (crack openin...

Microwave curing of repair patches provides an energy efficient technique for rapid concrete repair. It has serious economic potential due to time and saving especially repairs in cold weather which can cause work stoppages. However, the high temperatures resulting from combination microwave exposure accelerated hydration cementitious materials need be investigated prevent durability problems p...

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 58 % ...

Firms continue to focus more attention on how to make use of the Internet for commercial purposes. Traditional firms are integrating their existing market channels and their online presence, into what is often called click-and-mortar e-commerce. In this paper we will discuss how click-and-mortar e-commerce generates synergies and customer value, and what implications it has for the type of cust...

Abstract Bangladesh is connected through bridges and many of them are experiencing damages due to the aging concrete, weathering effect, or excessive loading. Repair retrofitting those becoming inevitable make operational. In this study, a concrete bridge have been investigated non‐destructive tests numerical methods. A repair strategy for damaged girders has developed using epoxy injection, sh...

Polymer-modified mortar is made of with the addition copolymer acrylic. An acrylic one additives suitable for repair because it can increase overall durability cement. This research investigates bond strength between polymer-modified and concrete substrate treatment on surface. investigation focused determining effect copolymers strength. In addition, this study also investigated surface a bond...
