C. Glass strips are driven into the layer according to the pattern required
D. After final grinding is over, oxalic acid mixed with water is spread over and rubbed hard with soft material
Answer: Option C
Solution (By Examveda Team)
In constructing a terrazzo floor, the statement that glass strips are driven into the layer according to the pattern required is incorrect.Instead, the glass chips or aggregates are mixed with the terrazzo binder before being spread over the surface, not driven into it.
The correct process involves preparing a base course, laying a thick layer of cement concrete, and then applying the terrazzo mixture on top.
After laying the terrazzo, it is ground to a smooth finish, and oxalic acid is used to enhance the surface's shine.
