SikaPlast® PH 8397 may be combined with many other Sika® Products.
Compatible with all types of cement and cementitious materials.
Important: Always conduct trials before combining products in specific mixes and contact our Technical Service Department for information about specific combinations.

SikaPlast® PH 8397 is a ready-to-use liquid which is dispensed in to the concrete together with the mixing water. The plasticizing 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 SikaPlast® PH 8397 to dry aggregate or cement is not recommended.
Thorough mixing is essential and a minimum mixing cycle, after the addition of the SikaPlast® PH 8397, of 60 seconds for forced action mixers is recommended.

Optimum dosage of SikaPlast® PH 8397 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 Master Builders Solutions representative.
For addition information on SikaPlast® PH 8397 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 8397 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.

Clean all tools and application equipment with water immediately after use. Hardened / cured material can only be mechanically removed.
