Cover blocks center to center distance :- 600 mm to 1 meter
Beam shall not have width less than 200mm
For 750mm depth beam provide :- Side Face Reinforcement & also called STIFFNOR
Width to depth ratio of beam should be more then 0.3
Yoke interval in column should be 600 m / 2feet
Diameter of needle for compaction in column = 40mm

Why steel always circular ?

Because circular patterns stress distribution equally.

CONCRETE POURING IN RAIN- how to pouring concrete in rainy days

CONCRETE POURING IN RAIN https://askciviltech.blogspot.com/2020/06/knowledge-of-cement-concrete-behaviour.html CONCRETE POURING:- Water is a major component of all concrete. which is mixed with cement and causes it to hydrate and regain strength. After concrete is laid water can do more harm than good as driving rain. Pouring concrete in the rain can compromise its strength, leading to increased tendency to dust and scaling. Once damage is done. it can be difficult to fix and will often ruin the appearance of the finished surface. Do not let it rain on your parade. Here are some tips to prevent and prevent rain-damaged concrete. Advice for pouring concrete in the rain Despite modern weather forecasting techniques and radar maps, an unexpected rain shower can develop without warning, especially during the hottest months of the year. If rain is in the forecast, you should postpone pouring a large concrete until conditions improve. Even if rain is not predicted you should...

Basic civil engineering interview questions

Basic civil engineering interview questions Minimum spacing between chairs is 1 metre sand used in India obtained from Ennore ( Tamil Nadu) Concrete cube is filled in 3 layers Minimum percentage of steel in column is 0.8 % of gross area 1 yard is equal to 3 feet Slump cone field in 4 layers Binding wire required of 1 metric ton is 8 kg to 10 kg Technical name of binding wire is Annealed wire What is ties ? Ties are transverse reinforcement of column What is stirrups ? Stirrups is transverse reinforcement of beam What are the concrete test ? Slump test Compressive strength test Water permeability test Water absorption test Type of slumps True slumps - the concrete mass after the test when slumps evenly all around without disintegration is called TRUE slump . Shear slump - when one half of the concrete mass slide down the other is called Shear slump. This type of slope obtained in a lean concrete mix Collapse slump - when the sample is collapse due to addin...
