Q2. What the difference between Dry mortar and Wet mortar
Ans. 
Dry mortar is a mixture of cement, sand, and additives in dry form, while wet mortar is a mixture of the same ingredients in wet form.
• Dry mortar is pre-mixed and requires only the addition of water before use.

• Wet mortar is mixed on-site and can be adjusted for consistency as needed.

• Dry mortar is easier to store and transport than wet mortar.

• Wet mortar has a shorter shelf life than dry mortar.

• Dry mortar is commonly used...read more

Q1. What is compressive straight of bat bricks
Ans. 
Compressive strength of bat bricks refers to the maximum load-bearing capacity of the bricks under compression.
• Compressive strength is an important property of bricks used in construction.

• It is measured in units of force per unit area, such as N/mm² or psi.

• The compressive strength of bat bricks can vary depending on factors such as the type of clay used, the firing temperature, and the moisture content.

• For example, a t...read more
