Formation of shlykovite and ASR-P1 in concrete under accelerated alkali-silica reaction at 60 and 80 °C

Throughout the full exposure period, the rate and amount of alkali leaching from the unwrapped AAR-4.1 prisms (60°C) and the unwrapped ASTM prisms (38°C) is comparable for almost all

• In general for CEM I binders, exposure to 60°C leads to considerably higher water absorption compared with corresponding test series exposed to 38°C (one exception is

The Raman spectra of the crystalline ASR products in concrete C2–38 are identical to the ones obtained in concrete from civil engineering structures [15,16] and to ASR

The  calculated  pH  for  the  outermost  points  of  the  cores  are  erroneous  (represented  with  the  empty  markers  in  Figure  12).  This  is  because 

This current TC is focusing on the following Work Packages; WP1- Performance based testing concepts, WP2 - Relationship between results from laboratory and

All the models are based on the assumption that an internal pressure is developed at aggregate level due to the formation of ASR reaction products (commonly named also as

The aim of this master thesis is to investigate the effect on mechanical properties and degree of damage in concrete exposed to accelerated Alkali-silica reaction (ASR) and
