Usage

SikaControl®-170 Poro is particularly suitable for lightweight porous concrete:
  • Preferably with raw density of 500 – 1500 kg/m³
  • As thermal insulation
  • As a compensation / insulation layer in construction and civil engineering.
  • As a light, flowable filling mix e.g. for excavations, old sewers, formwork blocks, etc.

Application

Application Information

Compatibility

SikaControl®-170 Poro may be combined with other Sika® admixtures and with additives used in gypsum, mortar and concrete productions. Always conduct trials before application in specific mixes. Contact our technical service for information about specific combinations with other Sika admixtures. Please be noted that substances such as, but not limitted to, oils, form oils, protective agents of concrete mixers and machineries or aluminum particles may cause an uncontrolled variation of air voids and density of the finished product. Please consult Sika Technical Department for further suggestions.

Dispensing

Performance of concrete mix shall be greatly enhanced if SikaControl®-170 Poro dispensed through a foam generator device. SikaControl®-170 Poro 

shall be added to the gauging water and dispensed into the concrete mixer. Avoid adding SikaControl®-170 Poro to the dry mix. Mixing time varies depending on the mixing conditions and the performance of the concrete mixer. A minimum mixing duration of 60 seconds is recommended. If SikaControl®-170 Poro added directly to the transit mixer, the mixing shall be continued at the maximum revolutions for at least 1 minute per m³ of concrete mix. In all cases, a minimum mixing duration of 5 minutes should be carried out to obtain a uniform concrete mix.
Consumption

Recommended dosage

0.3 - 1.5 % by weight of total binder. Higher dosages may be used depending on the mix design, raw materials, climatic conditions and project requirements. Consumption of SikaControl®-170 Poro through a foaming device shall be in the range of 0.15 – 0.30 kg per 100 liters of foam. The required amount of foam depends on the desired density or other targeted properties of the final product. Trial mixes must be performed to establish the exact dosage rate based on required concrete perfomance.
