Berolan LPC-908

CE-Nr.: 1139-CPD-0802/09

Application

Berolan® LPC 908 is an air entraining agent for use in concrete. The active agent concentration was chosen low consciously to permit a practicable dosing. The air entraining admixture was specially developed for use in dry concrete. It effects a frost resistant and frost and de-icing salt resistant concrete matrix by adoption of micro air pores.The small-sized spherical pores supersede the fine grain particles. They raise the slipping effect in the fresh concrete and cause an improvement of working and compaction when fitting the concrete. By preliminary tests the required dosage should be detected, because air pore formation is dependent on several factors (concrete composition, cement grade, fresh concrete consistency, temperature, mixing time and others). The air entraining admixture should be intermixed homogeneously in the dry concrete. The mixing time of the fresh concrete in the compulsory mixer should not be less than 60 seconds. The formation of air pores in concrete with very low consistency is very hindered. Suitability tests should be run, because raising air contents cause decreasing strengths. While fitting the concrete, tests of air content should be done at regular intervals by trained personal. Adaptations of the dosage on actual conditions may be necessarily. The regional prevailing technical rules and standards about concrete and air entrained concrete should be considered.

Berolan ST-100

CE-Nr.: 1139-CPD-0802/09

Application

Berolan ST 100 was designed as additive for use in concrete. The active agent concentration was chosen consciously low to permit a practicable dosing.The special for use in dry concrete developed stabilizer causes a reduction of segregation without rising the air content. Berolan ST 100 reduces the rebound and the dust loading while production of shot concrete. By preliminary tests the required dosage should be detected, because the effect may be dependent on several factors (concrete composition, cement grade, fresh concrete consistency, temperature, mixing time and others). The stabilizer should be intermixed homogeneously in the dry concrete previous to the addition of water. The mixing time of the fresh concrete in the compulsory mixer should not be less than 60 seconds. Qualification tests should be run, because raising stabilizer contents cause decreasing strengths.While fitting the concrete, tests of the consistence should be done at regular intervals by trained personal. Adaptations of the dosage on actual conditions may be necessarily.The regional prevailing technical rules and standards about concrete should be considered.

Berolan LPC-1

Application

Berolan LPC-1 is a coated air entrainer based on modified resin soap, with improved

handling properties, low caking and moisture sensibility.

Berolan LPC-1 is especially optimized for the incorporation of micro air pores into

hydraulic hardening dry mortar systems like:

- Cementitious tile adhesives and joint grouts

- Renders

- EIFS (Exterior Insulation Finishing Systems)

- Thin set floor tile adhesives

- Masonry mortars

- Repair mortars

- Concrete

Berolan LPC-1 shows an excellent stable behaviour and a high processing security. The content of air is much less influenced by mixing time and dosage, compared to synthetic air entrainers.

Dosage recommendation: 0,01 – 0,05 % on dry mortar.
