SikaPlast® PH 3845

(former MasterPolyheed® 3845)

Water reducing superplasticizer for the production of high quality day-to-day ready-mix concrete

SikaPlast® PH 3845 is an economical admixture based on modified polycarboxylic ether. The product has been primarily developed for applications in ready mix and site-batched concrete.
SikaPlast® PH 3845 is specially designed to allow for mid to high range mix water reduction while maintaining flexible degrees of slump retention without retardation.
SikaPlast® PH 3845 is free of chloride & low alkali. It is compatible with all types of cements.
SikaPlast® PH 3845 admixture provides the concrete producer with the ability to immediately create the optimal admixture system for changing and fluctuating regional raw materials, environmental conditions and project requirements.
SikaPlast® PH 3845 admixture gives the concrete producer the ability to consistently produce and deliver quality day-to-day concrete.

Application

Application Information

Dispensing

SikaPlast® PH 3845 is a ready-to-use admixture to be added to the concrete as a separate component. Optimal result is obtained if SikaPlast® PH 3845is poured into the concrete mix right after the addition of the first 80% of the mixing water, i.e., when all solids are wetted. Avoid adding the admixture to the dry aggregates.
Consumption

Recommended Dosage

The normally recommended dosage rate of SikaPlast® PH 3845 is:

0.4 to 1.2 litre per 100kg of total cementitious material.
Other dosages may be recommended in special cases ac-cording to the specific site conditions. In this case, please consult our Technical Services Department for advice.
