Slump needed for 1m3 in M25 grade concrete is typically around 75-100mm.

• Slump is a measure of the consistency of concrete.

• For M25 grade concrete, the slump required is usually between 75-100mm.

• The slump test is conducted as per IS: 1199-1959 standard.

• Proper slump ensures the concrete is workable and can be easily placed and compacted.

The number of cubes needed for 1 cubic meter of RCC concrete varies depending on the size of the cubes used.

• The number of cubes needed for 1 cubic meter of RCC concrete can be calculated by dividing the volume of the concrete by the volume of each cube.

• For example, if the size of the cube is 0.1 cubic meters, then 10 cubes would be needed for 1 cubic meter of RCC concrete.

• It is important to consider the size and shape ...read more

Core cut in soil can be tested through various methods such as visual inspection, laboratory testing, and geophysical techniques.

• Visual inspection of the core cut for any visible signs of soil composition, structure, and moisture content.

• Laboratory testing to analyze the physical and chemical properties of the soil sample obtained from the core cut.

• Geophysical techniques like ground penetrating radar or seismic surveys...read more

HVAC stands for Heating, Ventilation, and Air Conditioning. It is a system that controls the temperature, humidity, and air quality in a building.

• HVAC systems heat or cool air and distribute it throughout a building using ductwork.

• Ventilation systems bring fresh air into the building and remove stale air.

• Air conditioning systems remove heat from the air to cool it down.

• HVAC systems can include components such as furnac...read more

Data centers are facilities that house computer systems and associated components, such as telecommunications and storage systems.

• Data centers store and manage large amounts of data for organizations.

• They typically have backup power supplies, cooling systems, and security measures in place.

• Data centers can be on-premises or cloud-based, with cloud data centers being accessed remotely over the internet.

• Examples of data ...read more

To find a fault in an underground electrical cable, various methods can be used such as cable tracing, insulation resistance testing, and thermal imaging.

• Use cable tracing equipment to locate the path of the cable and identify any breaks or faults.

• Perform insulation resistance testing to check for any leakage or faults in the cable insulation.

• Utilize thermal imaging cameras to detect any abnormal heat patterns along th...read more

The budget breakup between Civil and MEP in a typical infra project varies depending on the project scope and requirements.

• The budget allocation for Civil and MEP (Mechanical, Electrical, and Plumbing) works in an infrastructure project is typically determined based on the project's design and specifications.

• In general, the Civil works budget includes costs for site preparation, earthworks, foundations, structural elem...read more
