Dosage:
Optimum dosage of DUCONMIX WR SP 300 should be determined in trial mixes. As a guide, a dosage ranges of 500mg to 1200mg per 100kg of cementitious material is usually suggested. Due to variations in concrete materials, job site conditions, and/or applications, dosages outside of the suggested range might be prerequisite.
Over dose effects:
- Air entrainment
- Bleed/segregation of mix, quick loss of workability
- Increased plastic shrinkage
- A slight overdose could not adversely affect the ultimate strength of the concrete and can gain higher strengths than normal concrete, provided it is appropriately compacted plus cured. Due allowance must be made for the effect of fluid concrete pressure on form work, and stripping times would be watched.
Application:
The hyper plasticiser will be DUCONMIX WR SP 300 high range water reducing, high early strength achievement type, Superplasticiser based on polycarboxylic ether formulation. The product shall have specific gravity of 1.09 & solids content not less than 34% by weight. The product will fulfil with ASTM C494 Type F and will be free of lignosulphonates, naphthalene salts as well as melamine formaldehyde when subjected to IR Spectra. DUCONMIX WR SP 300 is a ready to use liquid which is dispensed into the concrete together with the mixing water. The plasticising effect and water reduction are higher if the admixture is added to the damp concrete after 50% to 70% of the mixing water has been added. The addition of this admixture to dry aggregate or cement is not suggested. Automatic dispensers are available. Thorough mixing is essential and a minimum mixing cycle, after the addition of the DUCONMIX WR SP 300 of 60 seconds for forced action mixers is recommended.
Type:
ASTM C494: Type F
Color:
Light brown liquid
Packaging:
DUCONMIX WR SP 300 is available in 5kg, 10kg, 20kg & 250kg drums or bulk.
