Strength development in concrete Understanding

Concrete strength. Many factors influence the rate at which the strength of concrete increases after mixing. Some of these are discussed below. First, though a couple of definitions may be useful: The processes of 'setting' and 'hardening' are often confused: Setting is the stiffening of the concrete after it has been placed. A concrete can be 'set' in that it is no longer fluid, but it may

Factors Affecting the Mechanical Properties of Cement

A study has been conducted to investigate the mechanical properties of cement-mixed gravel using the unconfined compression test and the tensile test. Basic factors including the curing period, the water-binder ratio, the cement content, and the strain rate were evaluated. Ordinary Portland cement with fly ash was employed as the cementation agent for preparing cemented samples.

Workability of Concrete Definition Factors

The word “workability” defines an amalgam and composite of four concrete flow-making physical properties like mixability, transportability, mouldability, and compatibility.. You can’t ignore this physical parameter because of the fact that it effects the strength, durability, cost of labor, compaction effort, and also the final appearance.
