Analysis of the thermal behavior of Masonry Concrete Block with Internal Natural Element Coating

The search for constructive forms that are less aggressive to the environment has become increasingly relevant, in view of the scarcity of natural resources and population growth. With the current energy and environmental scenario in the world, it is possible to say that the situation is delicate, given the demand for energy by the population and the dependence on exhaustible natural resources and polluting the environment for it to be produced. This exacerbated use of energy can be related to the generation of artificial air conditioning for the thermal comfort of the inhabitants. In order to mitigate energy consumption inside buildings, this study aims to analyze the internal temperature of the environment after inserting the corn stalk inside the empty spaces of the concrete block used for conventional masonry. To verify the thermal performance of the concrete block filled with corn stalks, 5 prototypes were built with different constituent materials, and the internal temperatures were recorded using datalogger devices. The temperature analyzes took place in the spring, in the months of October and November, totaling 39 days of data collection, and through these data, it was possible to identify that yes, the junction of the manually molded concrete block and the filling of the corn stalk showed an improvement in the internal thermal performance in the prototypes built with this material.
