The images were captured by a high-resolution USB microscope with a 2.0 megapixel image sensor and video resolution capture of 1280 x 960, as presented in Figure [6]. The image capture rate was set at 5 frames per second, which was recorded in an AVI format, and the light was generated by LED lamps from the microscope itself.

Curing of cement concrete is defined as the process of maintaining the moisture and temperature conditions of concrete for hydration reaction to normally so that concrete develops hardened properties over time. The main components which need to be taken care of are moisture, heat, and time during the curing process. Contents:Why the curing of cement […]

specimens with uniform distribution of the applied current, the Randles model (see Fig. 18) is used for the analysis of transitory periods, however in on-site measurements this analogue model does not properly represent the phenomenon and therefore, the analysis based on the Randles model of transitory periods recorded in large

the damage and to observe its format and length. It was noticed that the infrared images are different depending on the heat source incident on the specimen. Therefore, group 2 was tested only for the more efficient heating (incandescent lamp). In the second stage, the infrared equipment was tested.

Specimens making Eighteen cylindrical specimens of 15 cm x 30 cm, as required in Brazilian Standard ABNT NBR 5738 [7] were molded; nine of them with the addition of 10% of wastes (cement, sand and waste ratio 3:6:1) and another nine specimens with the addition of 25% of wastes (ratio 1:2:1). The assays below were made on these specimens:

In the image below we see the 3 types of planar images and how they are orientated compared to the MIRA probe. The B-Scan is as previously discussed, whilst the D-Scan is at right angles to the Probe. The C-Scan is a plan view of the grid area collected. One purpose of these planar images could be to show a slab profile (see D-Scan).
