Learn Morewhich should be less than 30%. Based on these physical properties, a concrete mixture design with quality values of 20, 30, and 40 MPa was arranged. The concrete workability was determined to be 10 +/− 2 cm. The complete concrete mix design is shown in Table 1.

Learn MoreThe basic requirements for the design of concrete mix ratio are: 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 ...

Learn MoreConcrete toppings are recommended for use under abrasive conditions. Table 1 of SABS 0109-2:1992 "Finishes to concrete floors", gives detailed recommendations on the intricacies of screed flooring. What is not generally realised is that, in terms of material costs, a 30 MPa concrete topping is often cheaper than sand-cement screeding.
