Disadvantages Of Foam Concretefoam Concrete Mix Design Calculator

what is the foam concrete ?? and where can i use it,some foam concrete mixes include portland cement that is mixed with the cement and foam by itself or mixed with pulverized fly ash. it may also include limestone. each of these mixtures makes a cement product ideal for different applications, but typically all foam concrete products become more resistant when compressed and aren’t vulnerable to liquefication or settlement once hardened..expanding foam vs. concrete fence post: which is better,between expanding foam and concrete, expanding foam is the better option for setting fence posts. however, concrete is also a classic and viable option and can be done quite easily like expanding foam. the reason that expanding foam is such a great option is because it expands widely filling the surrounding cavities creating a strong seal. let’s get into the difference between expanding foam and concrete.
