## Theodolite Surveying

Theodolite surveying is that branch of surveying in which theodolite is used to measure the horizontal and vertical angles. A Theodolite is a very precise instrument, mainly used for determining the horizontal and vertical distances between two points. It can also be used for prolonging a line, measuring distances indirectly, as a level, like a …

## How to determine the Water Content of Soil? (7 Methods)

The moisture content or water content of soil mass is a quantitative measure of the wetness of a soil sample. Mathematically, water content for a given soil mass is defined as the ratio of the weight of water to the weight of soil.   Water Content, w = Weight of water / Weight of Soil …

## Self Compacting Concrete

Self Compacting Concrete is a highly flowable non-segregating concrete that can be placed in formworks without any external compaction. It gets compacted by means of its own weight.   Related Article: Types of Concrete Advantages of Self Compacting Concrete Self Compacting Concrete can be placed at a faster rate with no need for mechanical …
