The tremie concrete placement method uses a vertical or nearly vertical pipe, through which concrete is placed by gravity feed below water level. [4]The lower end of the pipe is kept immersed in fresh concrete so that concrete rising from the bottom displaces the water above it, thus limiting washing out of the cement content of the fresh concrete at the exposed upper surface.
The economic advantage of ferro concrete structures is that they are stronger and more durable than some traditional building methods. [citation needed] Ferro concrete structures can be built quickly, which can have economic advantages.

Cement content and water-cement ratio are important elements hereby. The comparison with standardized concrete is tested according to the following ...

Although livestock production serves as a source of income, it can provide additional economic values for rural families, often serving as a major contributor to food security and economic security. Livestock can serve as insurance against risk [ 45 ] and is an economic buffer (of income and food supply) in some regions and some economies (e.g ...
Direct reduction processes can be divided roughly into two categories: gas-based and coal-based. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.) in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).
The Henneke horse body condition scoring system is a numerical scale used to evaluate the amount of fat on a horse's body. It was developed in the early 1980s by Don Henneke at Texas A&M University with the goal of creating a universal scale to assess horses' bodyweight, [ 1 ] and was first published in 1983. [ 2 ]
