CBR stands for Code Based Routing, a method used in software development for routing messages based on code logic.

• CBR is a technique used in software development to route messages based on code logic

• It involves writing code to determine how messages should be routed

• CBR is commonly used in systems where routing decisions are complex and need to be dynamic

IS 2720 Part 8 is a standard for determining the water content of soil by oven drying method.

• IS 2720 Part 8 is a standard method used in geotechnical engineering to determine the water content of soil samples.

• The method involves weighing a soil sample, drying it in an oven, and then re-weighing to calculate the water content.

• The water content is calculated as the difference in weight before and after drying, divided by...read more

Admixtures are used in concrete to enhance its properties. Common types include water reducers, accelerators, and air-entraining agents.

• Water reducers: reduce the amount of water needed for workability without affecting strength

• Accelerators: speed up the setting and hardening process

• Air-entraining agents: create small air bubbles to improve freeze-thaw resistance

• Retarders: delay the setting time

• Superplasticizers: impro...read more

Concrete design mix and minimum cement content are determined by the applicable code.

• Concrete design mix is determined based on the required strength and durability of the structure.

• Minimum cement content is specified by the code to ensure adequate strength and durability.

• For example, ACI 318 specifies a minimum cement content of 564 kg/m3 for concrete with a compressive strength of 28 MPa.

• Other factors such as water-c...read more
