A optimization of ventilation concrete block in resistivity through the building wall.

Abstract

The purpose of this research was to study the resistivity optimization of ventilation concrete block and another way to use. Concrete vent blocks are commonly used in building construction in every area of the countries.  due to low cost, good availability and ease of use for experienced construction personnel . They also reduce construction times because they are larger (made of a mixture of sand and cement pressed into blocks).  Concrete vent blocks can be incorporated into the construction design to optimization in resistivity through the building wall by changing the positioning and arrangement of the concrete blocks – they can be installed either lying vertically or horizontally. The study consists of measuring the inside and outside surface temperatures of a test box using concrete vent block wall, concrete block wall, and comparing those temperatures to the outside air temperature.The results of the study show that the concrete vent block wall could reduce the inside air temperature better than the concrete block wall.  In the same amount of time, the concrete vent block wall could reduce the inside air temperature by 3.17^oC lower than a concrete block wall.
