SIKA M-BED STANDARD

Volume Stability: The gassing agent reacts with the alkaline cement paste in a controlled manner commencing with the addition of the gauge water. This regulated reaction produces a gas (in its molecular form), which is dispersed as minuscule bubbles throughout the entire mix, inducing a homogeneous expansion of up to 3%. The chemical reaction continues until the gassing agent is completely consumed (approx. 2 to 3 hours) leaving the set Sika® M-Bed® Standard in permanent contact with the structural member being grouted.

Range of Placing Consistencies: Flowability agents provide the mechanism, which allows Sika® M-Bed® Standard to be placed at consistencies ranging from dry-pack to flowable, with relatively low water/cement ratios still being maintained.

Strength Development: The rapid strength development, both in compression and in flexure, provides for early loading, specifically when used at the drier consistencies.

Large Temperature Range: Sika® M-Bed® Standard may be subjected to prolonged in-service temperatures ranging from sub-zero to 176°C (348°F) without significant variation in strengths.

Effective in Freeze/Thaw Conditions: Sika® M-Bed® Standard has been proved effective in the harsh northern climatic regions of Canada and abroad where conditions of freeze/thaw exist.

Effective in Wet Conditions: The absence of metallic aggregate or residue allows usage in most conditions encountered in exterior exposure such as wet-dry cycling and continuous wet.

Compatible with Steel: There are no chlorides present in Sika® M-Bed® Standard, therefore placement in conjunction with prestressing steel cables or reinforcing bars is not a constraint.

Formulated with inert, non-reactive aggregates to eliminate potential Alkali-Aggregate Reactivity (AAR).
