| Summary: | The process of curing concrete cylinders must be governed by the standards established by the ASTM (American Standards for Testing Materials) and the FEA (Federal Highway Administration). Currently there are several laboratories that offer the curing service fail in certain aspects. [1] "Initial Curing: Immediately after molding and finishing, samples should be recorded for a period of 48 hours in a temperature range of 16 to 27 ° C [60 to 80 ° F] and in an environment that prevents the loss of moisture of the specimens ". According to the ASTM, it is possible to raise different procedures as long as those observations are satisfied. Our project addresses the needs of the incubators in the common practices in the sampling of concrete cylinders, by means of a prototype for the initial curing of the concrete that allows keeping the specimens in an acceptable temperature range and that allows to carry out a good Cylinder curing service, either in fixed installations or on site. The prototype consists of the isolation of the concrete cylinders in a storage box connected to a cooling unit with pellet cells powered by a source and operated by a temperature microcontroller. For the resistance of the resistance to humidity, the difference in resistance to the temperature of its resistance thatoccurs microcracking. "[4] |
