There are various effects of fly ash on properties of hardened concrete such as strength and durability, creep and volume changes of concrete. This article discusses the concrete properties that are affected by use of fly ash in concrete. Effects of ...

CONCRETE MIX DESIGN PROCEDURE & EXAMPLE IS456

Concrete mix design is the process of finding the proportions of concrete mix in terms of ratios of cement, sand and coarse aggregates. For e.g., a concrete mix of proportions 1:2:4 means that cement, fine and coarse aggregate are in ...

PROPERTIES OF CONCRETE

Properties of concrete are influenced by many factors mainly due to mix proportion of cement, sand, aggregates and water. Ratio of these materials control the various concrete properties which are discussed below. Properties of Concrete are:Grades (M20, M25, ...

FACTORS AFFECTING WORKABILITY OF CONCRETE

Factors Affecting Workability of Concrete Each and every process and materials involved in concrete mixing affects the workability of concrete. Workability of concrete is measured in terms of ease with which it can be mixed, transported to construction site, ...

FACTORS AFFECTING CHOICE OF 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. In general, concrete mixes are designed in order to achieve a defined workability, strength ...

CONCRETE COMPRESSIVE STRENGTH VARIATION WITH TIME

Effect of Age on Concrete Strength The compressive strength of concrete is affected with its age. The concrete member capacity is usually a function of concrete cross-section dimensions, the steel bar area, the concrete compressive strength, and the steel reinforcement yield ...
