VARAPLAST PC 502

AN ULTRA HIGH PERFORMANCE SUPERPLASTICISER BASED ON MODIFIED POLYCARBOXYLIC ETHER

VARAPLAST PC 502 i has been primarily developed for applications in the ready mixed and precast concrete industries where the highest durability and performance is required. Super plasticizing action ofVARAPLAST PC 100 is different than conventional super plasticizers based on sulfonated melamine and naphthalene formaldehyde condensate, which create electrostatic repulsion of particles. VARAPLAST PC 502 initially create the same electrostatic repulsion and further stabilizers the mixes due to static repulsion of long lateral chains linked to the polymer backbone.

Uses

The excellent dispersion properties of VARAPLAST PC 502 make it the ideal admixture for precast and ready mixed concrete where low water cement ratios are required. This property allows the production of very high early and high ultimate strength concrete with minimal voids and therefore optimum density. . In low strength mixes upto 25N/mm2. The use of VARAPLAST PC 502 gives a combination of excellent initial workability and workability retention over a long period in cementitious like M-100 compositions concrete
