Nominal concrete proportions vary for different grades, typically ranging from 1:1.5:3 for M5 grade to 1:0.5:1 for M100 grade.

• M5 grade concrete typically has a proportion of 1:1.5:3 (cement:sand:aggregate)

• M20 grade concrete typically has a proportion of 1:1.5:3.5

• M40 grade concrete typically has a proportion of 1:0.75:1.5

• M100 grade concrete typically has a proportion of 1:0.5:1

Cement reinforcement concrete is a type of concrete that includes steel bars, mesh, or fibers to increase its strength and durability.

• Cement reinforcement concrete is commonly used in construction to provide additional strength and support to structures.

• The reinforcement materials, such as steel bars or mesh, are embedded within the concrete to help resist tension forces.

• Fibers, such as glass or synthetic fibers, can also be added to concrete to improve its durability and red...read more

To draw SFD and BMD for simply supported beam under UDL of 10KM/m, follow these steps:

• Calculate the reactions at the supports

• Draw the SFD by taking the upward forces as positive and starting from one end

• Draw the BMD by taking the positive moment as clockwise and starting from one end

• Mark the maximum values of SFD and BMD

• Check the equilibrium and compatibility of the beam

Water absorption for 1st class brick should be less than 20%.

• Water absorption for 1st class brick should be less than 20%.

• Excessive water absorption can lead to structural issues and decrease the durability of the brick.

• Water absorption can be determined by soaking the brick in water for a specified period and measuring the weight difference before and after soaking.

Concrete test is a procedure to determine the quality and strength of concrete used in construction projects.

• Concrete test involves various methods such as compressive strength test, slump test, and concrete mix design.

• Compressive strength test measures the ability of concrete to withstand loads before failure.

• Slump test measures the consistency and workability of concrete.

• Concrete mix design involves determining the proportions of various ingredients to achieve the desired s...read more

The 7th dimension of BIM refers to the integration of facilities management data into the BIM model.

• Facilities management data includes information about maintenance schedules, equipment specifications, and energy usage.

• This dimension allows for the seamless transition of data from the construction phase to the operational phase of a building.

• By incorporating facilities management data, BIM can help optimize building performance and reduce maintenance costs.

• Examples of facili...read more

Fe500 is a type of high-strength reinforcement steel used in construction.

• Fe500 stands for 'Fe' meaning iron and '500' representing the minimum yield strength of the steel in megapascals (MPa).

• It is commonly used in construction for its high strength and durability.

• Fe500 steel bars are used in reinforced concrete structures such as buildings, bridges, and highways.

• It is also known as TMT (Thermo-Mechanically Treated) steel.

• Fe500 steel has a higher resistance to corrosion and ...read more
