Advanced Methods of Concrete Mixture Design

5.3.1 Concrete Mix Design 03.22

5.3 MIX DESIGN METHODS 5.3.1 CONCRETE MIX DESIGN 1. Scope. This method covers the procedure for designing concrete mixes and is based on the absolute volumes of the various components of the mix, i.e.: the absolute volumes of cement (plain, blended or fly ash modified), aggregate, water and air in one cubic yard of concrete. 2. Procedure. 2.1.

Concrete Mix Design: Proportioning

Throughout concrete’s history, mixes have been designed with a wide variety of methods. It actually wasn’t that long ago that we were using the 1-2-4 method of proportioning by volume – 1 scoop of cement, 2 scoops of sand and 4 scoops of stone. The Panama Canal was built using this antiquated, volumetric mix design method.

Concrete Mixture Optimization Using Statistical Mixture Design Methods

Although mixture methods have been used in industry to develop products such as gasoline, metal alloys, detergents and foods, they have seen little application in the concrete industry. This paper describes an experiment in which a statistical mixture experiment was used to optimize a six-component concrete mixture subject to several performance constraints.

Mix Design Hints for Shotcrete

The dry-mix process is better suited for concrete containing lightweight porous aggregates than it is for a mixture with normal weight aggregate. It also requires the operator of the nozzle be exceptionally skilled in controlling water content and, therefore, consistency, strength and watertightness as the placement of the concrete progresses.

Concrete Mix Design

American Concrete Institute Method of Mix Design (ACI–211.1) This method of proportioning was first published in 1944 by ACI committee 613. In 1954 the method was revised to include, among other modifications, the use of entrained air. In 1970, the method of mix design became the responsibility of ACI committee 211.
