Modulus of elasticity of Concrete

As per IS 456 : 2000 Clasue 6.2.3.1 Page No. 16.

Modulus of elasticity of Concrete can be calculated by following formula:

Ec = 5000 √fck N/mm2

Where Ec is short term static modulus of electricity.

Actual measured values may differ by plus minus 20 % from the values obtained from the above expression.

Example :-

Q. As per IS 456:2000 , which one of the following correctly expresses the modulus of elasticity of Concrete ?

a) Ec = 0.7 √fck N/mm2

b) Ec = 500 √fck N/mm2

c) Ec = 5000 √ fck N/mm2

d) Ec = 5700√fck N/mm2

Correct Answer is c ) Option.

Comprehensive Productivity and Labor Estimation for Construction Activities

This is the productivity of construction works, including quantity, labor, and duration, which is very helpful information for all site engineers. Productivity, Labor, and Duration for Activities Excavation (Manual) Quantity : 8–10 cubic meters/day per laborer Labor : 10–15 laborers (for larger sites) Duration : As per the area/volume to excavate Mechanical Excavation Quantity : 80–120 cubic meters/day (using an excavator) Labor : 1 operator, 2 helpers Duration : Based on excavation size Manual Backfilling from Available Soil Quantity : 12 cubic meters/labor/day Labor : 6–8 laborers Duration : Based on total area/volume Backfilling from Brought-Out Soil Quantity : 15 cubic meters/labor/day Labor : 5 laborers (excluding transport equipment labor) Duration : Based on volume and transport logistics Sand Filling Quantity : 20 cubic meters/day (manual filling) Labor : 4–5 laborers Duration : Based on area and thickness Anti-Termite Treatment Quantity : 1,000–1,200 square meters/day (spray a...

Types Of Level In Construction

Complete Guide to Construction Levels Complete Guide to Construction Levels with Practical Explanations In construction and civil engineering, different levels are used to ensure proper alignment, stability, drainage, and functionality. Below is a step-by-step explanation of each level in logical order, with practical examples to help you understand them better. 1. Natural Ground Level (NGL) – The Original Surface Definition: The existing level of the ground before any excavation or filling. Practical Example: Imagine you buy land with an uneven surface. The NGL is the starting point before any construction activity. Why It’s Important? Used as a reference for leveling, excavation, and filling. Helps determine how much soil needs to be removed or added. 2. Existing Ground Level (EGL) – After Site Preparation Definition: The level of the ground after site clearing, but before exc...
