Nova Superfine

Superfine is a new generation supplementary cementitious material (SCM) with a built-in high tech content. In spite of its high finesse it does not increase water demand at the dosage range of 5 to 15 percent of normal OPC in general. In fact concrete slump is seen to be improved due to the dense packing of cementitious material, producing low void content. the use of Superfine results in hydrated cement matrix to comprise of very small pores. Superfine is a specially processed product based on high glass content with reactivity obtained through the process of controlled granulation. The raw materials are composed primary of low calcium silicates. The processing with other select ingredients results in controlled particle size distribution (PDS). The computed blain value based on fine particles size, Superfine Provides reduce water demand for a given workability, even up to 70% replacement level as per requirement of concrete performance.

Superfine can also be used as a high range water reducer to improve compressive strength or as a super workability aid to improve flow. Superfine can be used as practical substitute for silica Fume as per the result obtained. if the advantages of Superfine are observed in the concrete mix design, the initial rate of strength development was found to be increased or similar as that of silica fume.
