Firstly, the RC32/40 - is that the strength of the concrete? From other posts, I believe the R stands for reinforced as it will have rebar in it?
Jul 30, 2018· C35 also has special additives to reduce the likeliness of air bubbles forming, protecting against surface cracks from freezing temperatures. C40 Concrete Grade. C40 is an extremely strong commercial-grade concrete with 40 Newton/28 day strength. C40 is the ideal choice in the construction of large industrial support beams and foundations.
1, meet the strength grade of concrete design. 2, meet the concrete peaceability. 3, meet the durability of the use of concrete. 4, meet the above conditions to save cement and reduce the cost of concrete. The strength of concrete is divided into twelve grades, such as C7.5, C10, C15, C20, C25, C30, C35, C40, C45, C50, C55, C60 and so on.

Aug 30, 2020· 40 mm: Suggested Favorable Concrete Grade: C35/45: C40/50: C40/50: C40/50: Minimum Cover: 20 mm: 25 mm: 30 mm: 35 mm: The protection of reinforcement steel against corrosion depends on the porosity, the quality and the thickness of the concrete cover. The density and quality of the concrete cover are assumed using the stipulated concrete grade.
The C35 concrete strength mix is a strong and durable concrete mix used on the majority of construction fields such as Agricultural, Industrial, Commerical and Domestic. The C35 mix is ideal for loading bays or areas that bear constant heavy loads from …
C35/45 35 45 From Table 1, for all the concrete grades/strength classes, the cylinder strengths are higher than the cube strengths. For example, the concrete grade/strength class C20/25 concrete is expected to have a minimum cylinder crushing strength of 20MPa and the same

C35 Concrete. What is C35 concrete used for?: again a very durable concrete that is hard-wearing and able to withstand and support constant pressure. Unlike C30, C35 is mainly used to create external walls to support buildings and structural pilings. C35 concrete can be found supporting multi-storey car parks.
C35 concrete. Usually specified at design stage, this form of ready mix concrete is designed to comply with a compressive strength denoted by the class of mix. Mixes are measured in grades, with strengths ranging from 10 Newtons through to high strength concrete mixes available online at 45 Newtons.
