Final answer:
Glass blocks should not be used in columns. While they are a versatile building material suitable for uses in walls, partitions, roofs, and floors, they lack the necessary strength to bear the load of a building when used in columns.
Step-by-step explanation:
The answer to the question, "From among the choices, where shouldn't glass blocks be used?" is d. Columns.
Glass blocks are a versatile building material that can be used in many different applications. They are often used in walls and partitions to provide a unique aesthetic appeal and allow natural light to pass through, all while maintaining privacy. Glass blocks are also used in roofs and floors to create interesting visual effects and improve the illumination in a space.
However, it is most inadvisable to use glass blocks for columns as they do not have the necessary strength to support the weight loads of a building. Structure-wise columns bear a significant amount of the building's load, making material strength a top priority. The compressive strength of glass blocks is much lower than that of materials typically used for columns such as concrete or steel. Therefore, the use of glass blocks in columns would pose a risk to the structural integrity of a building.
