Description : DICT18 PNS is a high range water reducer as admixtures for concrete in the construction industry, high concentration naphthalene-based superplasticizer for concrete, also named Naphthalene Sulfonate Formaldehyde(SNF). 

Application
?  It is one of the basic ingredients for formulation of chemical admixtures for ready-mixed concrete and mortars.
?  It has a powerful dispersing action on concrete.
?  In the preparation of dry mortars.
? The production of flowing concrete reduces the water/cement ratio and consequently increases the strength of the hardened material.
? In reinforced concrete and constructions of monolith heavy-weight concrete of high compression strength.
?  In production of constructions of fine concreteIn production of dense-clad constructions, thin-slab structures and constructions with complex configuration.
?  In production of concrete mixes with the use of non-standard fillers and fine sands
?  In using of slag portland cement, pozzolan and aluminous cements.
?  As the basic ingredient in the formulation of chemical concrete admixtures


Advantages
? Increase concrete mix flow up to 16-21 cm and higher without lose of strength and durability of concrete (at constant water/cement ratio);
?  Increase strength characteristics of concrete up to 20% and more (owing to reducing of  water consumption at constant cement consumption and concrete mix flow);
?  Gain concretes with high water-proofing, frost-resistance (300 cycles and more) and corrosion resistance;
?  Reduce cement consumption in equally-flow mixes by 15-20%;
?  Reduce time and power inputs at thermal moisture treatment of concrete;
? Greatly reduce time and power inputs for vibrating of concrete mix, and sometimes fully  refuse vibrating.

Dosage
Added into concrete and mortar mixes in condition of water solution of working concentration in the amount 0.3-0.8% of dry substance from cement mass. Actual usage based upon individual  mix designs.
