Concrete Mixing: Options to Consider | Design Solid

Methods of Concrete Mixing. Concrete is a mix of sand, water, coarse aggregate, chemical admixtures, and cement. Several elements will determine the strength and durability of a concrete structure. The primary one among these is the method of concrete mixing you will choose for your construction.

FINISH a concrete mix. Concrete that is stiff or dry may be difficult to Handle, Place, Compact, and Finish and, if not constructed properly, will not be as strong or durable when finally hardened. A slump test can be used to measure the workability of concrete. See CHAPTER 3 Concrete Testing Workability is affected by: THE AMOUNT OF CEMENT PASTE

PDF] Concrete Mixing Methods and Concrete Mixers: State

As for all materials, the performance of concrete is determined by its microstructure. Its microstructure is determined by its composition, its curing conditions, and also by the mixing method and mixer conditions used to process the concrete. This paper gives an overview of the various types of mixing methods and concrete mixers commercially available used by the concrete industry.

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.
