| Detailed Description: |
Sodium Naphthalene Formaldehyde produces concrete with extremely workable characteristics referred to as high slump. PNS also allows concrete to be produced with very low water/cement ratios at low or normal slumps. Sodium Naphthalene Formaldehyde is ideal for use in prestress, precast, bridge deck or any concrete where it is desired to keep the water/cement ratio to a minimum and still achieve the degree of workability necessary to provide easy placement and consolidationSodium Naphthalene Formaldehyde Specification: Solid Content 92% min Moisture 8.0 % max Fineness 5.0% max PH value 7 - 9 Chlorides Content 2.0% max Surface Tension 68-72 Mn/m Cement Flowing Rate 230mm min Concrete Reducing Water Rate 18% min Sodium Sulfate Content 18% max (5%max is also available) Addition Rates Sodium Naphthalene Formaldehyde can be added directly or added in after melt. It can be added during mixing and after-mixing. The afterward approach can achieve better result. The suggested addition rate is 0.75%. Sodium Naphthalene Formaldehyde Direction Prepare solutions as required. Direct use of powdery agent is allowed. Alternatively the addition of the agent is followed by water moisturization (water-cement ratio: 60%). The agent can be combined with other externally applied agents if pilot development or laboratory experiment succeeds.
