C Concrete Mixes

At Monty Mix Concrete, we supply a wide range of C-grade concrete mixes to suit all types of construction projects. Each mix is carefully designed with a specific strength and application in mind, making it easy to choose the right concrete for the job.
Concrete mixes are graded by their compressive strength, measured in newtons per square millimetre (N/mm²). For example, C20 concrete has a strength of 20 N/mm².
