1.2 Alccofine Alccofine is a specially processed product based on high glass content with high reactivity obtained through the process of controlled granulation. It is a micro fine material of particle size much finer than other hydraulic materials like cement, fly ash, silica etc. being manufactured in India.

Strength enhancement of concrete incorporating alccofine ...

The value of flow decreases in silica fume mix concrete and hence the optimum super plasticizer dosage increases, which can be attributed to high specific surface of silica fume For carrying out tests on compressive strength, the grade of cement used was OPC 53. Two ternary blend of concrete were prepared, one containing Fly ash and Alccofine ...

An Experimental Study on the Compressive Strength of ...

silica fume in concrete introduces an inherent effect that leads to an increase in strength of concrete at the same water cement ratio. The water reducing effect is an important benefit of silica fume concrete. Silica fume has been recognised as a pozzolanic admixture that is effective in greatly enhancing mechanical properties.

Silica fume - Wikipedia

Cement is the most significant component in concrete. Large scale manufacturing of cement consumes more energy and release harmful products (Carbon dioxide) into the atmosphere that adversely affect the environment and depletes the natural resources. A lot of research is going on in globally concentrating on the recycling and reuse of waste materials from many industries.

Silica fume is an ultrafine material with spherical particles less than 1 μm in diameter, the average being about 0.15 μm. This makes it approximately 100 times smaller than the average cement particle. The bulk density of silica fume depends on the degree of densification in the silo and varies from 130 (undensified) to 600 kg/m 3.The specific gravity of silica fume is generally in the ...
