What is ASTM 387?
ASTM C387 / C387M – 17 Standard Specification for Packaged, Dry, Combined Materials for Concrete and High Strength Mortar.
What is the psi rating of quikrete?
4000 psi
QUIKRETE® Concrete Mix (No. 1101) is the original 4000 psi average compressive strength blend of portland cement, sand, and gravel or stone.
What is the standard psi for concrete?
3,500 to 4,000 psi
Each concrete structure has a normally acceptable psi range. Concrete footings and slabs on grade typically require a concrete of 3,500 to 4,000 psi. Suspended slabs, beams, and girders (as often found in bridges) require 3,500 to 5,000 psi.
What PSI is ASTM C387?
5000 PSI
ASTM International – ASTM C387 Standard Specification for Packaged, Dry, Combined Materials for Mortar and Concrete. 5000 PSI Concrete Mix exceeds the compressive strength requirements of ASTM C387, as shown in Table 1.
What is 6000 PSI concrete used for?
PRODUCT USE PSI 6000 can be used for any application requiring concrete in a minimum thickness of 50 mm (2”), such as slabs, footings, steps, columns, walls and patios.
How do you increase PSI in concrete?
of silica fume. The use of the silica fume alone will increase the strength of your concrete to 15,000 psi. Mix the course aggregate and silica fume for 1 1/2 to 2 minutes.
What is 6000 psi concrete used for?
Does higher PSI concrete crack less?
Higher strength concrete means you have more Portland cement in it which means you will have MORE shrinkage, not less, and thus more potential cracking.
What is the strongest quikrete?
QUIKRETE ProFinish 5000 80-lb High Strength Concrete Mix
- Gets stronger faster, walk on time 10-12 hours.
- Superior finishing characteristics and workability.
- 3 times stronger in 24 hours than standard concrete mix.
Is higher PSI concrete more brittle?
RE: 3000 psi vs 4000 psi concrete “Higher strength concrete is more brittle and less ductile.
What is the highest PSI concrete you can buy?
The most common use of high-strength concrete is for construction of high-rise buildings. At 969 feet, Chicago’s 311 South Wacker Drive uses concrete with compressive strengths up to 12,000 psi and is one of the tallest concrete buildings in the United States.
