Pozzolanic additives are used in the concrete production to enhance mechanical properties and durability of the material. Silica fume, metakaolin, rice husk ash and nanosilica are some of the additives that can be beneficial and to improve performance of the concrete. As pozzolanic additive particle size are normally smaller than those of cement, pozzolans in concrete can have dual effect - to improve physical particle packing and to react chemically with calcium hydroxide forming calcium silicate - hydrates.
