What are the Factors Affecting Workability of Concrete?
Factors affecting the workability of concrete are materials such as water content, cement concrete, sand and aggregate properties such as size, shape, grading, mix design ratio and use of admixtures.
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 ...
Concrete Compressive Strength Variation with Time
