This section covers mix design fundamentals common to all PCC mix design methods. First, two basic concepts (mix design as a simulation and weight-volume terms and relationships) are discussed to set a framework for subsequent discussion. Second, the variables that mix design may manipulate are presented. Third, the fundamental …

Conventional mix proportioning of RFA in concrete can not be used. To address this issue, a novel mix-proportioning method is developed using particle packing density and minimum paste theory. Fresh and hardened properties of newly developed mix were evaluated.

Concrete mix design is the process of selecting suitable ingredients of concrete and determine the relative proportions to produce concrete with certain performance and durability requirements.

The results showed that from 86% of the total mixes with similar w/cement ratios, cement content, and workability classes, the compressive strength of concrete mixes was higher than for those mixes prepared according to the standard mix design.

A popular simplified mix design method is that from BRE. Compressive strength is, in general, related to durability. The greater the strength the more durable the concrete. To satisfy the required compressive strength, a value for water/cement (w/c) ratio is estimated for an appropriate test age (generally 28 days) and cement type.

The experimental result of compressive strength for those selected concrete mix design methods with the 7th, 14th, and 28th ages has fulfilled the desire for concrete strength.
