Explanation

Studies have shown that the shape and size of the foundation pit have a significant influence on deformation and stability.

Explanation

The admixtures slow down the initial rate of hydration of cement or prolong the setting of cement paste in concrete.

Retarding admixtures are frequently required in hot weather conditions to facilitate delaying the setting time

Explanation

The finite element method (FEM) is a popular method for numerically solving differential equations arising in engineering and mathematical modeling.

Explanation

Water reuse is the method of recycling treated wastewater for beneficial purposes, such as agricultural and landscape irrigation, industrial processes, toilet flushing, and groundwater replenishing

Explanation

Many practical and proprietary methods exist to avoid plastic shrinkage cracking, including various curing methods, power floating, the use of cold water, shrinkage reducing admixtures, and fibres.

Covering concrete with plastic sheets or wet burlap is the most common practical concrete curing method.

Explanation

Ground water recharge includes recharge as a natural part of the hydrologic cycle and human-induced recharge, either directly through spreading basins or injection wells, or as a consequence of human activities such as irrigation and waste disposal.

Explanation

The energy extracted from the vaporised liquid as evaporation occurs will decrease the temperature of the liquid, resulting in a process known as evaporative cooling.

Explanation

Head is the change in water levels between the hydro intake and the hydro discharge point.

It is a vertical height measured in metres.

Explanation

The center of gravity of an object is where we can consider all of the weight of the object to be concentrated.

This is a useful concept in physics and engineering.
