Alccofine is a new generation of fine material, which is used to increase the workability and strength of concrete. It was found that the addition of Alccofine shows an early strength gaining property and long term strength. Alccofine concrete increases the compressive strength of concrete on all age.
Alccofine material increases the strength (both in compression and in flexure) to a large extent at approximately 10% replacement level of cement. It is seen that the 7 days’ compressive strength, when compared between control mix and cement replaced by 10 % Alccofine an increase of 25.5 %, is observed.
If the percentage level of Alccofine is increased beyond that level it acts as a filler material and yields good workability to the concrete.
