General. Betonul B350 sau (C20/25) este un tip specific de beton utilizat în industria construcțiilor, denumit astfel datorită rezistenței sale caracteristice de 350 kilograme pe centimetru pătrat (kg/cm²). Acesta face parte dintr-o clasă de betoane cunoscute sub denumirea de betoane de înaltă rezistență (BIR).

The concrete mix design is also represented by their compressive strengths in Newton starting from 5 Newton, to higher values. In this case, C10 has 10 Newton strength, C20 has 20 Newton strength, and so on. Key factors to choose the grade of concrete. The key factors upon which the grade of concrete depends are as follows: Compressive Strength

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. The concrete mix ratio refers to the proportion of the components in concrete (cement, water, sand, and stone). There are two methods: one is to use a variety of materials amount per 1 cubic meters, such as ...
