Foam additive Sika® Lightcrete-400

for concrete

Sika® Lightcrete-400 is a universally utilisable foaming agent for the production of lightweight porous concrete for use in recreational rooms. For low emission foam mortars Targeted density and strength adjustment Suitable in neutral and alkaline binder systems Usage Sika® Lightcrete-400 is particularly suitable for light-weight porous concrete: Preferably with raw density of 0.5 - 1.5 kg/dm³ As thermal insulation As a compensation / insulation layer in structural construction and civil engineering As a light, flowable filling mix e.g. for excavations, old sewers, formwork blocks, etc. For utilisation in recreational rooms Advantages With Sika® Foam devices SG 70 or SG S9 P, Sika® Lightcrete-400, water and air generate a stable foam. This foam is then mixed into the output concrete in the concrete mixer. The resulting air pore content in the mortar cause: Low emission lightweight porous concrete An easily workable, flowable consistency Pumping capability due to stable air pores A targeted bulk density setting and strength setting An improved thermal insulation Packaging Drum: 200 kg Replacement container: 1000 kg Colour Fluid / colourless - light yellow Composition Organic surfactant Shelf life Minimum of 1 year shelf life in sealed containers. Mix before using after longer storage times. Storage conditions Protect against frost, strong sunlight and contamination. Utilise clean tanks and containers when delivered in bulk.
