What is the process to calculate the amount of Portland cement needed to achieve a grout density of 12.5 lbs/gallon?
The amount of Portland cement needed can be calculated by first determining the weight of the water used and then subtracting it from the desired grout density.
Given:
- 124 gallons of water used
- Water weighs 8.33 lbs/gallon
To find the weight of water used, we multiply the volume of water by its weight per gallon:
124 gallons * 8.33 lbs/gallon = 1034.92 lbs
Next, to achieve a grout density of 12.5 lbs/gallon, we subtract the weight of the water from the desired density:
12.5 lbs/gallon - 8.33 lbs/gallon = 4.17 lbs/gallon
Therefore, you would need 4.17 pounds of Portland cement per gallon of water to achieve an overall grout density of 12.5 lbs/gallon.
Calculating Portland Cement Needed for Grout Density
The process of calculating the amount of Portland cement required to achieve a specific grout density involves understanding the weight of water used and the desired density.
To start, we are provided with the information that 124 gallons of water have been used, with each gallon of water weighing 8.33 lbs. By multiplying the volume of water used by its weight per gallon, we can determine the total weight of water used:
124 gallons * 8.33 lbs/gallon = 1034.92 lbs
After determining the weight of water, the next step is to calculate the difference between the desired grout density and the weight of water. In this case, the target grout density is 12.5 lbs/gallon. By subtracting the weight of water from the desired density, we can find out how much Portland cement is needed to reach the specified density:
12.5 lbs/gallon - 8.33 lbs/gallon = 4.17 lbs/gallon
Therefore, to achieve an overall grout density of 12.5 lbs/gallon, you would need to use 4.17 pounds of Portland cement per gallon of water. This calculation ensures that the grout mixture reaches the desired density for optimal performance in various applications.
