Form work stripping time Vs Compressive strength of Concrete
Gopal Mishra
The strength of concrete increases with age. The table shows the strength of concrete at different ages in comparison with the strength at 28 days after casting. Age Strength percent 1 day 16% 3 days 40% 7 days 65% 14 days 90% 28 days 99% So, the minimum stripping time of concrete should be such thaRead more
What is Built up area and Super built up area?
Gopal Mishra
Built-up area and super built-up area is generally used in real-estate. It is used to calculate the cost of property per square feet or square meter. The built-up area is the carpet area plus the thickness of the outer walls and the balcony. The Super built-up area is the built-up area plus a proporRead more

How to Test Quality of Steel Reinforcement at Construction Site?
Gopal Mishra
I have not seen any test being carried out at the site for testing the quality of reinforcement steel. For its quality, a lab test is required. Also the test certificate from the manufacturer can be obtained to ascertain the quality of steel.
Admixtures in concrete for to Delay Setting Times
Gopal Mishra
Any admixtures used in concrete, it is as per the recommendations of the manufacturer. Refer to the manufacturer's specification for the quantity of admixture to be used per cubic meter of concrete to delay the setting time.
Form work stripping time Vs Compressive strength of Concrete
Gopal Mishra
Dear Seshachalam, the compressive strength of concrete does not depend on the formwork stripping time. Formwork stripping time is specified in order to prevent deflection and stability of the structural member. Compressive strength of concrete mainly depends on the quality control during mixing, traRead more
What is the Applications of Unified Soil Classification System?
Gopal Mishra
Unified soil classification system is adopted by ASTM D-2487-98 and IS:1498-1970 for classification and identification of soils for general engineering purposes. Refer this article details on Unified Soil Classification System
