Embodiment Construction
[0027] The method for the observation reinforced concrete rust crack that the present invention is based on two-stage rust crack model concrete implementation below in detail, includes but not limited to the concrete specimen (being called for short the first specimen) of complete rust crack, rust expansion crack penetrating the concrete protective layer , and the sample preparation and observation of the concrete specimen (referred to as the second specimen) with incomplete rust cracks and rust swelling cracks that have not yet penetrated the concrete protective layer.
[0028] Step 1: Configure low-viscosity epoxy resin
[0029] Use the epoxy resin (i.e. glue A) and curing agent (i.e. glue B) produced by Jinhong glue industry, and configure according to the ratio of volume ratio A glue: B glue = 2.5:1; after configuration, stir evenly along the same direction; The fresh epoxy resin after stirring has a certain viscosity and greater fluidity. At this time, after dipping a sma...
