MAPEI Performance Enhancer/ A
Grinding aids for masonry cement.

Description

MA.P.E./A are air-entraining agents formulated for grinding artificial and natural masonry cements. Artificial masonry cements are obtained by grinding clinker together with one or more inert material (in general limestone). Natural masonry cements are obtained by burning natural marls at 900 °C, and are characterized by low mechanical strengths but good workability.
MA.P.E./A confer to artificial masonry cements characteristics similar to those of the natural ones (workability, adhesiveness, resistance to freeze-thaw cycles, etc). MA.P.E./A can also further improve the performance of natural hydraulic masonry cements. Specific formulations of MA.P.E./A also allow mill output increases.

Characteristics

MA.P.E./A improve both air entraining and water retention. Air entraining can reach 15% to 18% improving the workability of the product. Water retention can easily exceed 95% (based on ASTM standards).
Air is entrained in micro-bubbles, homogeneously distributed, improving workability, yield per surface unit and resistance to freeze-thaw cycles. Micro-bubbles, with controlled diameter
and high stability, act as a lubricant between mortar layers, improving flow and workability.
Water retention prevents the mortar mixing water from migrating towards the external substrate, improves adhesiveness and helps to avoid cracks formation.

Usage

MA.P.E./A are formulated to improve the characteristics of natural and artificial hydraulic masonry cements. They have to be added to the mill during grinding, for a correct dispersion and to maximize the performances.

Chemical-physical data

Please refer to the appropriate safety data sheets.

Dosage: 0,6-1,0 kg/t

The optimum dosage depends on the type and fineness of the masonry cement. In any case, it has to be found through a reliable industrial trial, preferably with the help of MAPEI Cement Additives Division technicians.
MA.P.E./A should be added to the clinker on the mill feed conveyor belt or sprayed in the first mill compartment utilising a membrane or piston dosing pump.

Packaging

MA.P.E./A are available in plastic tanks (1.100 Kg net), in flexytanks 22-24 tons or in bulk trucks.

Storage

Maintain the additives at a temperature above 2°C. In normal conditions MA.P.E./A shelf life is at least 24 months.

Technical assistance

The MAPEI Cement Additives Division specialists are available to optimise the grinding circuit during the industrial trials and to suggest the most suitable dosage system.

Safety instructions

During the usage of MA.P.E./A it is recommended to respect the usual rules of industrial hygiene and manipulation of the chemical products. For further information please refer to the safety data sheet.

Technical Data Sheet

MAPEI Performance Enhancer /W
Pack set inhibitors, strengths and flow enhancers

Description

MA.P.E./W are highly concentrated grinding aids formulated with only selected raw materials, to guarantee absolute constancy of quality and superior performance.
They are additives formulated to improve cement quality (early and/or ultimate strengths, flow) and to aid cement grinding, increasing mill production.

Characteristics

MA.P.E./W also guarantee, besides all the advantages which come from the usage of the grinding aids (refer to MA.G.A./C), remarkable increments in early and ultimate strengths and an improvement of the workability (flow) of the cement paste and mortar.
At equal fineness MA.P.E./W are able to increase mechanical strengths thank to a better granulometric distribution of the finished cement and to a higher rate of calcium silicates hydration, which can be significantly modified.

Applications

MA.P.E./W may be successfully utilized in the grinding of blended cements, (i.e. pozzolanic, blast furnace slag and fly ash cements) and in all cases where it is necessary to improve the cement flow.
MA.P.E./W are generally formulated to reach the goals placed by the cement factory. The achievable strength increment may be used to improve the quality of the binder or, keeping cement quality unaltered, it is possible to substitute up to 4-6% of clinker with other constituents.
In normal conditions the strength increases are in the range of 20-50% after one day and 5-15% after 28 days.
These formulations, which are specifically oriented towards improving the water demand of the cement, are especially used in the production of pozzolanic and fly ashes cements.

Chemical-physical data

Please refer to the appropriate safety data sheets.

Dosage: 1,0 - 3,0 kg/t

We suggest the higher dosage threshold, if the aim is the substitution of clinker points with blended material (i.e. blast-furnace slag, fly ash, pozzolan) or the strong reduction of the water demand of the cement.
The optimum dosage has, in any case, to be found through a reliable industrial trial, preferably with the help of MAPEI Cement Additives Division technicians.

MA.P.E./W should be added to the clinker on the mill feed conveyor belt or sprayed in the first mill compartment utilising a membrane or piston dosing pump.

Packaging

MA.P.E./W are available in plastic tanks (1.100 Kg net), in flexytanks 22-24 tons or in bulk trucks.

Storage

Maintain the additives at a temperature above 2°C. In normal conditions MA.P.E./W shelf life is at least 24 months.
