Robustrade DMCC Interview Questions and Answers

Batching plant RMC moisture correction involves testing moisture content of raw materials, adjusting water-cement ratio, and monitoring throughout production process.

• Test moisture content of raw materials before batching

• Adjust water-cement ratio based on moisture content to achieve desired consistency

• Monitor moisture levels throughout production process and make corrections as needed

• Use moisture probes or meters to accurately measure moisture content

The water cement ratio for M-25 grade concrete is typically around 0.45.

• The water cement ratio for M-25 grade concrete is usually in the range of 0.45 to 0.5

• It is important to maintain the correct water cement ratio to ensure the strength and durability of the concrete

• Excess water can weaken the concrete and lead to cracking and other issues

The maximum cement usage in RCC is typically around 450 kg/m3.

• Maximum cement content is usually limited to around 450 kg/m3 in order to prevent excessive heat generation and cracking.

• Higher cement content can lead to increased shrinkage and reduced workability of the concrete mix.

• Excessive cement usage can also result in higher costs and environmental impact.

• It is important to carefully balance the cement content with other materials like aggregates and water to achieve the d...read more

Agg maximum water absorption refers to the maximum amount of water a material can absorb.

• Agg maximum water absorption is an important factor in determining the quality of aggregates used in construction.

• It is typically measured by soaking the aggregate in water for a specific period of time and then determining the increase in weight.

• Higher water absorption can indicate the presence of pores or cracks in the aggregate, which can affect the strength and durability of the concr...read more

The formula for concrete cube testing involves calculating the compressive strength of the concrete sample.

• The formula for calculating compressive strength is F = P/A, where F is the compressive strength, P is the maximum load applied to the cube, and A is the cross-sectional area of the cube.

• The compressive strength is usually reported in megapascals (MPa).

• The formula is used to determine the quality and strength of the concrete mix.

• Concrete cube testing is essential for ens...read more

IP conflict can be resolved by releasing and renewing IP address, checking for duplicate IP addresses, and configuring DHCP.

• Release and renew IP address using command prompt or network settings

• Check for duplicate IP addresses in the network

• Configure DHCP to assign unique IP addresses to devices

• Use static IP addresses for devices that require a fixed IP address

• Restart the router or switch if necessary
