- Q1. Natural sand has 8% moisture, can an RMC plant run?
- Ans.
Yes, an RMC plant can run with natural sand having 8% moisture.
Natural sand with 8% moisture is within acceptable range for RMC production.
The moisture content can be adjusted during the batching process.
Proper mixing and curing can still result in high-quality concrete.
Regular testing and monitoring of moisture levels is important to ensure consistency.
- Q2. What is paste ration?
- Ans.
Paste ration is the ratio of paste to water in a mixture, commonly used in laboratory settings.
Paste ration is calculated by dividing the weight or volume of paste by the weight or volume of water in a mixture.
It is often used in quality control processes to ensure consistency and accuracy in formulations.
For example, a paste ration of 2:1 would mean there are two parts paste for every one part water in the mixture.
