Concrete Blocks and Pavers Mix Design and Manufacturing
Mix Design Mix design mainly depends on the strength required & quality of material available. The main ingredients in manufacturing solid concrete blocks are: 1) Cement 2) Fly ash 3) Crushed sand (0-3mm) 4) Aggregates (5-10mm) Typical mix design for solid concrete blocks is given below, Mix design for block grade –7.5 Mpa (target strength)

Concrete Mix Ratios
Concrete mix ratio is a vital topic in concrete mix design. The four basic ingredients for making concrete are: Portland cement, sand, aggregate (stone) and water. The strength of concrete mixture depends on the ratio in which these four ingredients are mixed.

Factors affecting Concrete Mix Design
Design of concrete mix for a particular grade of concrete involves proper selection of relative proportions of cement, sand, and coarse aggregates. While designing a concrete mix, it is always tried to obtain a minimum strength which is equal to characteristic strength of concrete but concrete must have the desired workability and durability. Concrete mix design is mainly classified as;

Concrete Mix Design: Proportioning
When we teach mix design courses, the most frequent comment we get is, “Just give me a mix design.” To do so would be regarded as improper, foolish even. No one does this because a successful concrete mix design at one plant will not always work at another. All concrete is, and always should be, considered localized to a specific manufacturer. Since raw materials, especially aggregates
