DSF 315 CRYSTALLINE ADMIX
Concrete admixture in powder form for waterproofing and protection of concrete. It creates crystals which close porous and hair cracks on surface of concrete. It can be used at concrete production plants (before adding water) or on-site (after mixing cement with water). Ideal for waterproofing of foundations, underground areas, water tanks, swimming pools, etc.
Crystal growth, cementitious powder, waterproofing system added to concrete as an admixture. The product can be used in the ready mix plant with the form of powder, directly added in the pre-weighted dry parts of concrete (in the lift-band), before the water addition or by addition in the mix truck, at the job site, right after the mixing (with electric mixer) with water – in the special mixing pails with measure. Mixing water ratio: mix well ½ of 18 Kg bag with 11.5 Lt water. The small packaging of 3.75 Kg pail is convenient for the production of waterproofed mortars or small quantity of concrete in a small mixer. Mixing time in the mix truck or small mixer is at least 5 min. The recommended PENETRON ADMIX® ratio for permanently waterproofed concrete is 0.8-1% by weight of cement. For regular concrete ~300 Kg cement, we use 3 Kg product powder per m3 of concrete. E.g. for 9 m3 mix truck we use: 3 Kg x 9 = 27 Kg, that is 1½ PENETRON ADMIX® bag. It is easier to cut in half the bags, then mix 3 half bags in 3 mixing pails with 11.5 Lt water each. For the production of waterproofed mortars (cement content >250 Kg/m3), the mixing of 0.5-1.0 Kg PENETRON ADMIX® per 50 Kg of cement is recommended.
PENETRON ADMIX SOLUBLE BAGS
Crystal growth, cementitious powder, waterproofing system added to concrete as an admixture. Same technology as the above existing packaging of PENETRON ADMIX®, but with the ability, due to its water soluble packaging, of adding it directly to the mix truck (without previous mixing with water). Also, it contains a special traceable coloring (green) indicator for the right dosage laboratory control. Based on the indicative ratio of 0.8-1% by weight of cement, we add, one by one the water soluble bags, in the mix truck, same quantity as the total m3 of concrete of the mix truck. Attention: mix in the mix truck in high speed for at least 5 - 10 min, after the addition of the last package of the soluble bag.
