Stiffness damageRecently, many composite materials have been used to strengthen and extend the service life for deteriorated concrete; particularly in the case of alkali-silica expansion (ASR). This study compares the effectiveness of carbon fiber reinforcement polymer (CFRP) and basalt fiber ...

Different constituents of concrete can have cracking behavior that varies in terms of the acoustic waveform that is generated. Understanding the waveform may provide insight into the source and behavior of a crack that occurs in a cementitious composite. In this study, passive acoustic emission (AE...
We respond quickly to both natural and man-made disasters, including fire damage, water damage, mold removal, and more. Learn More Concrete Restoration & Waterproofing Our team performs concrete restoration and waterproofing repairs on concrete structures, parking structures, and curtain walls. ...
Alkali-silica reaction (ASR) leads to damage in various concrete structures worldwide. The internal stresses that lead to cracking are caused by the formation and swelling of the ASR products within the aggregates of the concrete. The increasing stress developing in affected aggregates eventually le...
Cracks and damage to the part of the concrete structure are the results of the formation of this expansive gel. There are several ways to minimize this reaction, out of which Lithium Nitrate compound is believed to reduce the reaction between alkalis (present in the cement) and silica (...

9). The additional water flow from concrete surfaces inward can also be calculated based on the gradient of water pressure as discussed in Section 3.2. At the structural level, the frost damage is rather non-uniform depending on the temperature boundary and placement of reinforcing bars (Fig. ...
In the 1940’s, a reinforced concrete (RC) railway bridge located in central Johannesburg was constructed using Witwatersrand Quartzite, at t
