The alkali–silica reaction (ASR), more commonly known as concrete cancer, is a deleterious swelling reaction that occurs over time in concrete between the highly alkaline cement paste and the reactive amorphous (i.e., non-crystalline) silica found in many common aggregates, given … Meer weergeven To attempt to simplify and to stylize a very complex set of various reactions, the whole ASR reaction, after its complete evolution (ageing process) in the presence of sufficient Ca cations available in solution, … Meer weergeven The mechanism of ASR causing the deterioration of concrete can thus be described in four steps as follows: 1. The very basic solution (NaOH / KOH) attacks the siliceous aggregates (silicic acid dissolution at high pH), converting the poorly … Meer weergeven ASR can be mitigated in new concrete by several approaches: 1. Limit the alkali metal content of the cement. Many standards impose limits on the "Equivalent Na2O" content of cement. 2. Limit the reactive silica content of the aggregate. … Meer weergeven Two types of heavy aggregates are commonly used for nuclear shielding concrete in order to efficiently absorb gamma-rays: baryte (BaSO 4, density = 4.3 – 4.5) and … Meer weergeven The cracking caused by ASR can have several negative impacts on concrete, including: 1. Expansion: The swelling nature of ASR gel increases the chance of expansion in concrete elements. 2. Compressive strength: … Meer weergeven There are no curative treatments in general for ASR affected structures. Repair in damaged sections is possible, but the reaction will continue. In some cases, when … Meer weergeven The only way to prevent, or to limit, the risk of ASR is to avoid one or several of the three elements in the critical triangle aggregate reactivity – cement alkali content – water: • by selecting non-reactive aggregates after testing them … Meer weergeven WebHydraulic cement instantly stops running water or leaks in concrete and masonry, by expanding as it hardens to form a perfect seal.
