Portland cement concrete consists of what four primary elements?

Expert Solution & Answer
Check Mark
To determine

The four primary elements of Portland cement concrete.

Explanation of Solution

The four primary elements of Portland cement concrete are,

  1. Portland Cement
  2. Portland cement is produced by crushing and pulverizing a cautiously prepared mix

    of limestone, marl, and clay and by burning all the mixture at a highest temperature

    (about 2800°F ) to develop a clinker.

  3. Coarse Aggregates
  4. 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.
  5. Fine Aggregates
  6. 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.
  7. Water
  8. 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.

For the truss shown in Fig 2, determine the nodal displacement and member forces using the stifness method for all elements of the truss. Assume for each member A = 0.0015 m2 and E = 200 GPa
5. Two 400 g blocks are connected by a rigid rod. The Blocks can rotate freely at the ends of the rod, so the rod does not apply any moments to the blocks. The blocks are in contact with the wall and floor, and can slide without friction. The system is released from rest when X=24cm and Y=18cm. Ignore the mass of the rod. What are the initial accelerations of Block A and Block B just after being released? Hint: See Assignment 4, Problem 2 for help getting a relationship between the acceleration of Block A and the acceleration of Block B. Y m = 400 g A | L g I 1 I I X B m = 400 g
The momentum of the force F = -100 i -70 j + 50 k around the point O is MO = 410 i- 300 j + 400 k, Determine the coordinates of the point through which the line of actionof F intercepts the yz plane.
