    Designing a High Strength Concrete Mix Concrete

    The age at which concrete must develop its high strength is an important factor in the design of a mix. If high early strength is required, it can often be achieved by modifying an existing mix design to incorporate: (1) Type III rather than Type I or Type II portland cement; (2) additional cement

    Seven Must-Use Concrete Admixtures (Additives)

    ApplicationsBenefitsAdvantagesSet retarding concrete admixtures are used to delay the chemical reaction that takes place when the concrete starts the setting process. These types of concrete admixtures are commonly used to reduce the effect of high temperatures that could produce a faster initial setting of concrete. Set retarding admixtures are used in concrete pavement construction, allowing more time for finishing concrete pavements, reducing additional costs to place a new concrete batch plant on the job site and helps eliminate cold jo

    Early High Strength Concrete Advantages and Challenges

    High Strength concrete is also one of them. The history of high strength concrete is about 35 years old, in late 1960s the invention of water reducing admixtures lead to the high strength precast products and structural elements in beam were cast in situ using high strength concrete.

    Accelerating admixtures have a relatively limited effect and are usually only cost effective in specific cases where very early strength is needed for, say, access reasons. They find most use at low temperatures where concrete strength gain may be very slow so that the relative benefit of the admixture becomes more apparent.

    High-Strength Concrete

    High-strength concrete is specified where reduced weight is important or where architectural considerations call for small support elements. By carrying loads more efficiently than normal-strength concrete, high-strength concrete also reduces the total amount of material placed and lowers the overall cost of the structure.
