There are 1,097 concrete additives for strength suppliers, mainly located in Asia. The top supplying countries are China (Mainland), Malaysia, and Turkey, which supply 99%, 1%, and 1% of concrete additives for strength respectively. Concrete additives for strength products are most popular in Domestic Market, South Asia, and Mid East.
Today with all the additives and mix designs for different applications, the deciding factors after all the ingredients are added is still the compressive strength measured today in PSI (Pounds per square inch) that the concrete can withstand before failing.

However, precast concrete products needed to be stripped within one day to be competitive with castinplace concrete. The solution was to increase the 28day compressive strength of the concrete mix to between 4,000 and 5,000 psi.
Concrete strength is typically enhanced through the use of compounds consisting of microsilica (also known as silica fume), which when added to the mix, create a significant increase in compressive and flexural (bending) strength in concrete, as well as a reduction in its permeability.
The experiment showed that the compressive strength of cement concrete increased as the temperature increased during a curing time. On the other hand, if the temperature was kept constant, the compressive strength tended to increase as the curing time increased. The compressive strength of the cement concrete was increasing within the
compressive strength of brick What is the compressive strength of steel Compressive strength measures the largest compression force the material can withstand before it loses its shape or fails.
Increase strength (compressive, tensile or flexural). Increase durability or resistance to severe condition of exposure. Decrease permeability of concrete. Control expansion caused by the reaction of alkalies with certain aggregate constituents. Increase bond of concrete to steel reinforcement. Increase bond between existing and new concrete.
The compressive strength test results are listed in table (6). CONCLUSION The mixtures that contain admixtures have compressive strength greater than control mixture, In this work, the effects of addition of the strength increase with the decrease of w/c. ratio.
