Q1. Why construction joint is provided in structure?
Ans. 
Construction joints are provided in structures to allow for the placement of concrete in different stages and to prevent cracks.
• Construction joints are used to separate different concrete placements, typically due to time constraints or logistical reasons.

• They help to reduce the risk of cracks forming in the structure by controlling where the concrete shrinks and expands.

• Construction joints are commonly used in large c...read more

Q1. What is M 10 & compressive strength?
Ans. 
M 10 is a designation for a concrete mix with a compressive strength of 10 megapascals (MPa).
• M 10 refers to the mix design of concrete, indicating the proportions of cement, sand, and aggregate used.

• Compressive strength is the maximum amount of compressive stress a concrete specimen can withstand before failure.

• M 10 concrete typically has a compressive strength of 10 MPa or 1450 psi.

• It is commonly used for non-structur...read more
