We manufacture and supply a wide range of construction materials including aggregates, asphalt, ready mix concrete and precast concrete products.
In this situation an ST4 mix may be used but only for small quantities of concrete. In all other cases the appropriate ... This is equivalent to
Grading requirements of aggregates and prescribed mixes for concretes. ... of ST4 (C20) concrete at medium ... Mix Proportions for Standardised Prescribed Concretes
The mix proportions given in Table 4 below for standardised prescribed concretes will produce approximately one cubic metre (1m³) of fully compacted concrete. In effect, this is a recipe for how to make concrete of a particular strength, with a particular slump, using specific aggregates.

The ST1 is equivalent to a lean-mix C7.5 mix, described on the Concrete Mixes page, while the ST4 is a medium-strength mix equivalent to a C20 mix. Typical uses for each - the ST1 might be used as a bedding for kerbs or edgings while the ST4 would be used as the haunching.
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.
