Construction

AAC is also known as Autoclaved aerated concrete which is a lightweight, precast, foam concrete building material which is suitable for producing concrete masonry unit like blocks.

The advantages of AAC masonry over the conventional brick masonry are as follows :-
– AAC bricks are eco-friendly whereas conventional bricks are not.
– On AAC block dead load on the structure is low which reduces the consumption of cement, steel and water whereas using red clay brick there’s a heavy dead load on the structure.
– AAC blocks emits less heat in the atmosphere due to less use of cement, steel and concrete whereas on the other hand red clay bricks emits high heat to the atmosphere.
– AAC blocks have less material wastage whereas conventional red clay bricks have high material wastage.
– Thus, AAC have high sound insulation properties and red bricks have low insulation property.

Traverse surveying is a method to establish control networks. Traverse networks involve placing survey stations along a line or path of travel, and then using the previously surveyed points as a base for observing the next point.

There are two types of traverse surveying , they are:

1. Closed traverse: When the lines form a circuit that ends at the starting point, it is known as a closed traverse.

2. Open traverse: When the lines form a circuit ends elsewhere except the starting point, it is said to be an open traverse.

So, for the construction of road projects open traverse is used because in this we can extend roads for infinite distances.
