Date: 9/1/1983. Abstract: High-strength concrete is considered to be concrete with a compressive strength higher than 6000 psi (42.8 MPa). An extremely strong and dense con-crete can be produced with a 24 hour compressive Strength higher than 14,000 psi (100 MPa) with conventional methods of production, room temperature curing, and cement-based binders and admixtures.
