Mar 31 2019 · It is defined as a measure of an unreinforced concrete slab or beam to resist failure in bending. In other words it is the ability of the concrete to resist bending. Flexural strength is usually anywhere from 10 to 15 percent of the compressive strength depending on the specific concrete mixture.

Seven Must-Use Concrete Admixtures (Additives)

Nov 20 2019 · Concrete Admixtures Air-Entrainment. Air entrained concrete can increase the freeze-thaw durability of concrete. This type of admixture produces a more workable concrete than non-entrained concrete while reducing bleeding and segregation of fresh concrete. Improved resistance of concrete to severe frost action or freeze/thaw cycles.

They are added to concrete to enhance the workability improve resistance to thermal cracking and alkali–aggregate reaction and to enable reduction in cement content.

12 Types of Concrete Mixers Used in Home Improvement and

Batch concrete mixers are the most widely used types of mixers used to make concrete. Unlike continuous mixers batch mixers mix and discharge concrete periodically one batch after the other. The batch mixers consist of rotating drums with blades inside. In this mixer all the ingredients are fed into the drum or pan in the desired proportion

ACI mix designMemphis

ACI Mix Design Strength and Durability-- In general the minimum compressive strength and a range of w/c ratios are specified for a given concrete mix. Possible requirements for resistance to freeze-thaw and chemical attack must be considered. Therefore a balance or compromise must be made between strength and workability.
