Conventional grade C20, C25 and C30 concrete mix ratio ...
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.
What is the mix ratio for grade C30 concrete? - Quora
IS 456-2000 has designated the concrete mixes into a number of grades as M10, M15, M20, M25, M30, M35 and M40. In this designation the letter M refers to the mix and the number to the specified 28 day cube strength of mix in N/mm2.

Mix designs for concrete block
aggregate design batch weight by adding the design batch weight of the fine and coarse aggregate as found in Step 3. 5c. Determine how much cement is required in the mix. Multiply the weight determined in 5b by the de-sired cement-to-aggregate ratio. Aggregate design batch weight cement-to-aggregate ratio = cement (in lbs.) For example: 1

Concrete Mix Design Calculation : M20, M25, M30, M40 Grade Concrete Concrete mix design is a procedure of selecting the suitable ingredients of concrete and their relative proportions with an objective to prepare concrete of certain minimum strength, desired workability and durability as economically (value engineered) as possible.
Concrete Mix Design Guide - Civil Engineering
The following is a design guide for selecting proportions for initial concrete mix design for normal weight concrete. This guide references ACI 211.1-91 (Reapproved 2009), “Standard Practice for Selecting Proportions for Normal, Heavy weight, and Mass Concrete”, specifically Chapter 6, “Procedure” and Appendix 1, “Metric (SI) System
Concrete Grade Used in Construction
Feb 12, 2018 · Concrete Grade C60/20: This concrete grade is used for the most important part of the structural concrete element which is “Column” and “Shear wall.” The highest quality concrete grade is the high strength concrete grade. This is the grade used for beams and girders, columns and other major structural members.

The basis for calculating the volume is described in the ASTM C 94, Specification for Ready Mixed Concrete. The volume of freshly mixed and unhardened concrete in a given batch is determined by dividing the total weight of the materials by the average unit weight or density of the concrete determined in accordance with ASTM C 138.

3000 psi vs 4000 psi concrete - Structural engineering ...
I have found over in Asia on project specific batch plants that one might have a 3000 psi mix design but when the concrete is tested at 28 days, it'll be 4000 or more from time to time and usually always more than 3500. Hundreds of tests on several projects have confirmed this. We have had some 20 MPa concrete test out at nearly 40 MPa.
