Chapter 20, Problem 1P
Portland cement concrete consists of what four primary elements?
Expert Solution & Answer
To determine
The four primary elements of Portland cement concrete.
Explanation of Solution
The four primary elements of Portland cement concrete are,
- Portland Cement Portland cement is produced by crushing and pulverizing a cautiously prepared mix
- Coarse Aggregates The coarse aggregates are used in Portland cement concrete are materials of inert that are not going to react with cement and normally are comprised of gravel, which is crushed, stone, or blast furnace slag.
- Fine Aggregates Sand is majorly used in the fine aggregate in Portland cement concrete. for this material the specifications usually include requirements of grading, cleanliness and soundness.
- Water The major water requirement stipulated is that the water used also should be capable fordrinking. This water is needed for the quantity of organic matter, acids, oil, and alkalis should not be higher than the allowable amount in drinking water.
