How much force is required to break concrete?

The force required to break concrete depends on various factors such as the type of concrete, its age, and the specific conditions of the concrete. In general, the compressive strength of concrete is measured in pounds per square inch (psi). For typical concrete mixes, the compressive strength can range from about 2,500 psi to over 10,000 psi. Therefore, the force required to break concrete can vary widely, but it typically takes thousands of pounds of force to break through concrete.

What is concrete's setting time?

Dependant on if you have additives with the concrete and how much water is in the mix. In general concrete will achieve 80 - 90 percent strength within in 24 hours


How much sand is required for one cubic meter of concrete for slab?

For one cubic meter of concrete used in a slab, approximately 0.3 to 0.5 cubic meters of sand is typically required, depending on the specific mix design. A common concrete mix ratio for slabs is 1:2:4 (cement:sand:aggregate), which translates to about 0.4 cubic meters of sand for each cubic meter of concrete. However, the exact amount may vary based on the desired strength and workability of the concrete.

What is the strenght of concrete?

The strength of concrete is primarily measured by its compressive strength, which indicates how much load the material can withstand without failing. This strength is typically expressed in megapascals (MPa) or pounds per square inch (psi) and varies depending on the concrete mix design, curing conditions, and the materials used. Standard concrete typically has a compressive strength of about 20 to 40 MPa (2,900 to 5,800 psi), while high-strength concrete can exceed 70 MPa (10,000 psi). Other factors, such as the water-cement ratio and the use of additives, also influence concrete's overall strength and durability.


How much IQ is required to solve a Rubik's Cube?

Solving a Rubik's Cube does not require a specific IQ level. It mainly depends on practice, patience, and understanding of the cube's algorithms.


How much aggregate cement sand is required to make 1 cube concrete?

To make 1 cubic meter of concrete, the typical mix ratio for a standard concrete is about 1 part cement, 2 parts sand, and 3 parts aggregate (1:2:3). This means you would need approximately 350 kg of cement, 700 kg of sand, and 1050 kg of aggregate. The total volume for these materials should add up to 1 cubic meter when factoring in the mixing process and compaction. Adjustments can be made based on specific project requirements or desired concrete strength.
