MethodsBatching of rapid-hardening concrete – Concretum

Batching methods for rapid-hardening concrete In order to mix rapid-hardening concrete different methods and site organisations are possible. Due to the fact that rapid-hardening concrete has a defined open time and has to reach a certain strength within a certain time the duration of batching and transporting should be as short as possible.

Batching, Mixing, Transporting, and Handling Concrete, Chapter 10

BATCHING Batching is the process of measuring concrete mix ingre-dients by either mass or volume and introducing them into the mixer. To produce concrete of uniform quality, the ingredients must be measured accurately for each batch. Most specifications require that batching be done by mass rather than by volume (ASTM C 94 or AASHTO M 157).

Design of Normal Concrete Mixtures Using Workability

The workability-dispersion-cohesion method is a new proposed method for the design of normal concrete mixes. The method uses special coefficients called workability-dispersion and workability-cohesion factors. These coefficients relate workability to mobility and stability of the concrete mix. The coefficients are obtained from special charts depending on mix requirements and aggregate properties.

CIVL 1101 - Part 9 - Handling and Placing

Batching and Mixing. The main advantage of this technique over other methods is that concrete can have as little as 1/3 the slump of concrete consolidated by hand. Lower slump mixes are also less prone to segregation. Overvibration will bring excessive paste to the surface, enhances bleeding, and causes loss of entrained air.
