what does c35 and c40 mean in concrete

Concrete Mix vs Strength

Jul 28, 2018If you work it out per kg, for 100kg dry mix, the 5:1 Ratio would have less All-In Ballast and therefore less aggregate than a 6:1 mix ratio. (83.33kg : 16.66kg for 5:1, or 85.71kg : 14.28kg for 6:1) does this mean that the 5:1 mix would be weaker than the 6:1 mix? Thanks, Get price

Compressive Strength of Concrete Concrete Cubes

Dec 08, 2017The capacity of concrete is reported in psi – pounds per sq. inch in US units and in MPa – mega pascals in SI units.This is usually called as the characteristic compressive strength of concrete fc/ fck. For normal field applications, the concrete strength can vary from 10Mpa to 60 Mpa. Get price

How to Calculate the Load Bearing of Concrete

This note reflects the specific mix you will order throughout your project. Write this number down. This is the base load-bearing strength of your concrete. If you are doing a smaller home project with no special accelerants added to your mix, your load-bearing strength per concrete yard will be 3,000 psi. This is the standard psi of a common mix.

Eurocode 2: Design of concrete structures EN1992

Concrete strength at a time t (3.1.2) Expressions are given for the estimation of strengths at times other than 28 days for various types of cement f cm(t) = β cc(t) f cm where f cm(t) is the mean compressive strength at an age of t days β cc(t) = exp {s[1-(28/t)1/2]} The coeeficient s depends on type of cement: s = 0,20 for rapid hardening Get price

Density Of Concrete

A normal weight concrete weighs 2400 kg per cubic meter or 145 lbs per cubic foot (3915 lbs per cubic yard). The unit weight of concrete (density) varies depending on the amount and density of the aggregate, the amount of entrained air (and entrapped air), and the water and cement content. Get price
