Consumption
Recommended Dosage
Optimum dosage of SikaPlast PH 8399 should be determined with trial mixes. As a guide, a dosage range of 500ml to 1800ml per 100kg of cementitious material is normally recommended. Because of variations in concrete materials, job site conditions, and/or applications, dosages outside of the recommended range may be required. In such cases, contact your local Sika representative.
For addition information on SikaPlast® PH 8399 admixture or on its use in developing concrete mixes with special performance characteristics, contact your local Sika representative. Effects of over dosage A severe over-dosage of SikaPlast PH 8399 can result in the following:
- Extension of initial and final set
- Bleed/segregation of mix
A slight overdosing may not adversely affect the ultimate strength of the concrete and can achieve higher strengths than normal concrete, provided it is properly compacted and cured. Due allowance should be made for the effect of fluid concrete pressure on form work, and stripping times should be monitored. In the event of over dosage consult your local Sika representative immediately.
