The strength of ST4 concrete typically has a characteristic compressive strength of about 20 MPa (megapascals) when tested at 28 days. It is considered a medium-strength concrete, suitable for various structural applications such as residential foundations, driveways, and non-load-bearing walls. This grade of concrete provides good durability and workability, making it a popular choice in construction.
What else can I help you with?
Is st1 concrete stronger than st4 concrete?
ST1 concrete typically has a lower compressive strength compared to ST4 concrete. The designation "ST" refers to the strength class, with higher numbers indicating greater strength. Therefore, ST4 concrete is generally stronger and more suitable for structural applications requiring higher durability and load-bearing capacity than ST1 concrete.
What st4 and pav2 concrete made of?
st4 is just a standard type concrete probably comparable to c40 structural concrete, pav 2 is the equivalent to c35 concrete with air bubbles, mostly used in paving works
What is tensile strength of concrete?
The tensile strength of concrete is 10% of it's compressive strength.
How does the moisture affect the strength values of concrete?
the moisture of concrete is main strength for reinforced concrete structure
How does fineness modulus of aggregates affect the strength of concrete?
how does the fineness modulus of aggregate affect the strength of concrete
Is st1 concrete stronger than st4 concrete?

Therefore, ST4 concrete is generally stronger and more suitable for structural applications requiring higher durability and load-bearing capacity than ST1 concrete.
What class of concrete is stronger ST2 or ST4?
ST 4 concrete is the stronger out of the two. ST4 is equivalent of 16 kn at 28 day strength where as ST2 is only 8 kn at 28 day strength.
What st4 and pav2 concrete made of?

The tensile strength of concrete is 10% of it's compressive strength.
Is the characteristic strength of a concrete the same as the compressive strength?
Yes, the characterisrtic strength of a concrete is the same as the compressive strength
How does the moisture affect the strength values of concrete?
the moisture of concrete is main strength for reinforced concrete structure
What is the relation between tensile strength and compression strength in concrete?
tensile strength is approximately between .08 to .15 of compression strength in concrete
What is high strength concrete?
Concrete with compressive strength more than 55 MPa is known as high strength concrete.It is used in the construction of bridges, dams. etc.,High strength concrete is produced by adding normal constituents of concrete with admixtures.
How does fineness modulus of aggregates affect the strength of concrete?

What is the equivalent of M-30 cylinder strength concrete?
The equivalent concrete for M-30 cylinder strength is M-40 cube strength
What is the Equivalent cube strength of concrete over cylinder strength of concrete Any conversion between cube and cylinder strengths?
Cylindrical strength = 85% of Cube strength.
