What Causes Concrete to Crumble? Hunker
Concrete seems like a stable and permanent material, but it remains porous and will absorb water. When this water trapped inside the concrete freezes, it pushes the cement binder apart. This expansion, and the resulting contraction when the water melts again, causes crumbling.

How Concrete is Made? gharpedia
Concrete is made up of different ingredients, which have various functions. The properties of concrete mainly depend on the mixing of concrete ingredients i.e. cement, coarse aggregates, fine aggregates (sand), and water. Various other concrete ingredients can also be used such as admixtures, pigments, fibers, polymers and reinforcement.
Seven MustUse Concrete Admixtures (Additives)
Jun 13, 2019 · Waterreducing admixtures are used to obtain specific concrete strength using lower cement content. Lower cement contents result in lower CO2 emissions and energy usage per volume of concrete produced. With this type of admixture, concrete properties are improved and help place concrete under difficult conditions. Water reducers have been used
