Question

IIydraulic mortar which contains aluminosilicate can be used for (1) bleaching (2) antiseptic action (3) building construction (4) all

Short answer

Hydraulic mortar containing aluminosilicate is used for building construction (option 3).

Step-by-step solution

Identify the Main Component

Hydraulic mortar contains aluminosilicate, which is a key ingredient used in construction materials.

Analyze Options

Evaluate each option to see which ones are relevant to the use of aluminosilicate.

Option 1: Bleaching

Bleaching is a chemical process typically unrelated to aluminosilicate. Therefore, this option is not correct.

Option 2: Antiseptic Action

Antiseptic action usually involves substances that kill or inhibit the growth of microorganisms. Aluminosilicate does not have properties related to antiseptic action, so this option is not correct.

Option 3: Building Construction

Aluminosilicate is often used in construction materials due to its strength and durability. This makes option (3) correct.

Option 4: All

Since only option (3) is correct, option (4) cannot be correct as it implies all options are correct.

Key concepts

Aluminosilicate

Aluminosilicate is a compound that combines aluminum, silicon, and oxygen. It's a significant component in many construction materials.
These materials are known for their exceptional durability and resistance to harsh environmental conditions. The structure of aluminosilicate can vary, but it usually forms a complex network that enhances the strength of the material it is part of.
In hydraulic mortars, aluminosilicate plays a crucial role due to its ability to react with water gradually. This slow reaction helps in the setting and hardening process, providing a robust and stable structure. By facilitating these characteristics, aluminosilicate becomes invaluable in construction applications.

Construction Materials

Construction materials are substances used in the building of structures and infrastructure. These materials can be natural like stone and wood, or artificial like bricks and concrete.
Hydraulic mortar is a type of construction material that contains aluminosilicate. Because of this, it possesses excellent properties such as water resistance and durability, making it particularly suitable for structures exposed to moisture.
Common examples include:

• Cement
• Brick
• Concrete
• Glass
• Steel

Each material serves a different purpose in construction, chosen based on properties like strength, flexibility, and resistance to various environmental factors.

Material Properties

Understanding material properties is essential in selecting the right construction materials. Each material has unique properties that determine its suitability for different applications.
Some of the key properties to consider include:

• Strength: The ability to withstand loads without breaking
• Durability: Resistance to weathering, wear, and chemical attack
• Flexibility: Ability to bend without breaking
• Water Resistance: Prevents water penetration which is crucial for longevity
• Thermal Stability: Ability to withstand high temperatures without degrading

These properties are particularly significant when using hydraulic mortar in building construction. The presence of aluminosilicate enhances many of these characteristics, making the material highly effective and reliable.
