Multiplast AirEnt

Multiplast AirEnt air entraining admixture is surface active chemicals which cause small stable bubbles of air to beformed uniformly through a concrete mix. The bubbles are mostly below 1 mm diameter with a highproportion being below 0.3 mm. The main reason for using Multiplast AirEnt is to improve the freeze thaw and scaling resistance andhence the service life of concrete. The improved cohesion and compaction can also enhance the quality and life of concrete structures. Multiplast AirEnt is used for durable concrete exposed to thermal fluctuations around freezing point (0°C); lean concrete (cement content less than 250 kg/m³) with a low fine sand content for pumping; concrete with lightweight aggregates to improve the homogeneity, workability and application of the mix.

Recommended Uses:

• hydraulic works (dams, water channels, swimming pools, storage tanks) exposed to cold climates;
• floors, floor slabs, tunnels and car parks exposed to rainwater and cold climates;
• lightweight structural concrete elements (panels, floor beams, etc.).

Unique Features:

• Air entraining agents lower the surface tension of the water to facilitate bubble formation.
• Uniform dispersion is achieved by blending surfactants to increase the stability of the interfacial layer between air and water, preventing bubbles from coalescing.

Benefits:

• Increased resistance to the action of freezing and thawing
• Increased cohesion resulting in less bleed and mix segregation.
• Improved compaction in low workability mixes.
• Gives stability to extruded concrete
• Gives improved cohesion and handling properties to bedding mortars.
