Factors Affecting Concrete Mix Design Strength

The mixing of concrete constituent materials i.e. cement, water, aggregates and admixtures in specified proportions will produce a concrete of adequate strength. The mix design strength developed for a given type of cement is dependent on the following factors:Water/Cement ...

What are the Factors Affecting the Choice of Concrete Mix Design?

What is concrete mix design? Concrete mix design is defined as the appropriate selection and proportioning of constituents to produce a concrete with pre-defined characteristics in the fresh and hardened states.Moreover, concrete mixes are designed in order to achieve a defined ...

Mix Design of High Strength Concrete -Methods, Procedure and Example

Mix design of high strength concrete is influenced by properties of cement, sand aggregates & water-cement ratio have compressive strength above 40 MPa.To achieve high strength, it is necessary to use lowest possible water-cement ratio, which invariably affects the workability ...

Recommended Concrete Mixes for Various Types of Construction

Recommended Concrete Mixes for Various Types of Construction Works: Various types of concrete construction requires different concrete mixes for its construction. The recommended value of these concrete  mixes for various types of construction is presented in table below: Table: Recommended mixes for ...

Design of Concrete Structures for Durability

Generally concrete structures are designed for sizing and strength of structural members and not for durability. Durable design of concrete members as much important as design for strength, to give the structure long life.Safety of structural members does not only ...

CONCRETE MIX DESIGN USING CRUSHED SAND

The process of selecting suitable ingredients of concrete and determining their relative amounts with the objective of producing a concrete of the required, strength, durability, and workability as economically as possible, is termed the concrete mix design. The proportioning of ...

TRIAL AND ERROR METHOD OF CONCRETE MIX DESIGN

In Trial and Error Method of concrete mix design, the proportion of fine aggregate to coarse aggregate is find out by trial, which gives the maximum weight of the combined aggregate. The density of particle of fine aggregate and coarse ...

ACI Method of Concrete Mix Design – Procedure and Calculations

ACI method of concrete mix design is based on the estimated weight of the concrete per unit volume. This method takes into consideration the requirements for consistency, workability, strength and durability. This article presents ACI method of concrete mix design. ACI ...
