What is ST2 concrete mix?
ST2 concrete (also known as C25) is a highly versatile concrete mix that can be used in a variety of applications – including flooring or for mass-fill under footings and foundations.
What strength is ST1 concrete?
ST1 Concrete (also known as GEN0) is a lightweight, relatively weak concrete that is used for applications that require a firm base but no structural strength. It’s made up of cement, water, stone and graded sand. GEN 0 is ideal for areas such as drainage works and blinding.
What does St mean in concrete?
Standardised Prescribed Concrete (ST)
What strength is ST4 concrete?
ST4. ST4 is used for many domestic, agricultural and industrial applications and suitable as a wearing surface for light foot traffic such as garage floors, sheds bases, internal floor slabs, drain/channel bedding and benching. Strength: Assume 20N/mm2 at 28 days.
What is ST3 concrete?
ST3. ST3 is widely used for light duty domestic applications and foundations but not usually suitable as a wearing surface. It can be used to construct internal floor slabs providing they don’t contain embedded metal and is ideal for house floors with no permanent finish (e.g. carpet or laminate) flooring.
What is dc2 concrete?
FND2 / Z2 is a sulphate resistant concrete, for when you have sulfate soils or are laying on clay. The minimum cement content of the mix is 330kg per cubic metre. This type of concrete is often used for foundations of buildings, where it is likely that sulphate containing soil will be present.

What strength is Gen 3 concrete?
20 newtons
One of the most common lightweight mixes we deal with is GEN 3 / C20 concrete. With a strength rating of 20 newtons after 28 days, this mix is commonly used for domestic projects, but can also be used for certain commercial applications.
What is M40 concrete?
M40 grade stands for it’s a mix of concrete with a characteristic compressive strength of 40 N/mm2. The mix design procedure for M40 grade concrete as per ACI Method is discussed.
What does C20 concrete mean?
C20 Concrete Grade C20 or Gen 3 is rated at 20 Newton/28 day strength. This mixture can be used to form lightweight foundations and applications in residential projects. Typical uses for this grade of concrete are in the formation of internal floor slabs, driveways, garages, and sheds.
