Foam additive Sika® Luftporenbildner LPS A-94

for concrete

Sika® Luftporenbildner LPS A-94 is utilised for the manufacture of mortar and concrete with high resistance to freezing/thawing and de-icing salts. Even under difficult conditions such as e.g. in concrete road construction, the desired air pore content is securely achieved. Very small, evenly distributed air pores Suitable in neutral and alkaline binder systems Very long foam stability Usage Concrete road construction and bridge construction Road surfacing concrete Cap concrete Ready-mixed concrete with long travelling distances Air-entrained concrete in conjunction with plasticizers and superplasticizers Mixtures with low content of ultra-fines to improve workability Screeds Ready-mixed mortar Advantages Sika® Luftporenbildner LPS A-94 causes: The formation of the smallest, evenly distributed air pores even under difficult conditions An expansion possibility for freezing water A reduction of the capillary suction effect A substitute of fines This causes in mortar and concrete: An air pore system that fulfils the requirements of micro-air pore content and spacing factor A high resistance to freezing/thawing and de-icing salts A reduced capillary water absorption An improved workability by means of "ball bearing effect" Packaging Drum: 200 kg Replacement container: 1000 kg Bulk delivery: From 6 t Colour Fluid / Brown Composition Synthetic surfactants Shelf life Minimum of 1 year shelf life in sealed containers.
