What are the Types of Mineral Admixtures in Cement?
CB Sowmya
There are two types of admixtures: Mineral admixtures Chemical admixtures Mineral admixtures are mostly solids. Chemical admixtures are mostly liquids. The most common mineral admixtures are: Fly ash Ground Granulated Blast furnace Slag (GGBS) Rice husk ask Metakaolin Silica fume Sugarcane bagasse oRead more
There are two types of admixtures:
Mineral admixtures are mostly solids. Chemical admixtures are mostly liquids.
The most common mineral admixtures are:
The mineral admixtures are added majorly to modify the strength of the concrete and increase the compressive strength.. Since all these mineral admixtures are byproducts of some industrial process which otherwise would be dumped into landfills, it is also beneficial to the environment.

CB Sowmya
There are three types of members in prestressed concrete TYPE 1 - Tension is not allowed; Cracking is not allowed. TYPE 2 - Tension is allowed (within permissible stresses) ; Cracking is not allowed. TYPE 3 - Tension is allowed; Cracking is allowed within permissible stresses. Type 3 membersRead more
There are three types of members in prestressed concrete
TYPE 1 – Tension is not allowed; Cracking is not allowed.
TYPE 2 – Tension is allowed (within permissible stresses) ; Cracking is not allowed.
TYPE 3 – Tension is allowed; Cracking is allowed within permissible stresses.
Type 3 members are the most economical members because they allow cracking and thus use the elastic property of the materials.

There are four types of stabilization
Mechanical:
This includes compacting the soil to physically change the properties of the soil. The compaction can be either vibrating or dynamic.
Another way to mechanically stabilize the soil is to remove excess water from the soil.
Chemical:
The soil is stabilized by adding chemicals to the soil. The chemicals include cement, fly ash, lime, GGBS, bitumen, and pozzolana
Biological:
Planting trees will reduce erosion in highways close to rivers and canals. Trees will hold the soil particles together creating optimal soil porosity and retaining water.
Using Polymers:
These include using geopolymers, textiles, and other synthetically woven materials that have high strength.

See lessWhat are the problems associated with prestressed concrete piles?
CB Sowmya
The disadvantages are as follows Skilled labors are required to design the piles Prestressed structure is made up of high strength materials hence higher are the losses due to shrinkage. They are costlier than normal construction In the process of prestressing, additional equipments such as jacks arRead more
The disadvantages are as follows
Prestressed piles are cast in the factory or yard and then installed in a site. Since they are precast, they have the disadvantages associated with the precast technology.

CB Sowmya
The design life of an RCC structure is generally taken as 75 years. But that may increase or decrease based on the following factors. It is dependent on the quality of construction, quality of materials used, weather conditions, seismic conditions, maintenance of the building, etc. From the questionRead more
The design life of an RCC structure is generally taken as 75 years.
But that may increase or decrease based on the following factors. It is dependent on the quality of construction, quality of materials used, weather conditions, seismic conditions, maintenance of the building, etc.
From the question, when buying apartments, the builders will not disclose the genuine construction practice that was followed. So in order to be sure, it is best to test the structure using Nondestructive tests.
To know more about the nondestructive tests used to find the strength of the structure,
