Parameter
Product characteres
1. Adjustable working time (20 minutes to 2 hours)
The working time can be adjusted to 20 minutes ~ 2 hours by using ordinary retarder (L-tartaric acid) or special retarder "D300".
2. Excellent early strength development
By adjusting the dosage, the compressive strength can be regulated to over 10 MPa at 3 hours.
3. Long-term stability
As a cement-based material with stable composition, it will not hinder the cement hydration reaction. It features long-term stable strength development, and the strength will not decline.
4. Superior crack resistance
The product has micro-expansive property and almost no hardening shrinkage, thus exhibiting excellent early-age crack resistance.
Producti Applicationes
Grout rapidus durans, mortarium reparans rapidum durans, materiae auto-nivelantes, demoldatio rapida productorum concretorum, etc.

Proprietates physicae mortarii cum BEFORM addito (ad 20 ℃)
| Dosis BEFORM (%) | Tempus operis (min) | Compressiva Fortitudo (MPa) | ||
| 3h | 1d | 28D | ||
| 0 | 300 | - | 22.3 | 65.9 |
| 15 | 49 | 11.2 | 35.4 | 64.8 |
| 20 | 47 | 15.4 | 41.7 | 63.3 |
| 25 | 42 | 18.7 | 45.8 | 65.2 |
Proportio Mixturae Mortarii: (Cementum + BEFORM) / Sabulum = 1 / 1,5
Aqua / (Cementum + BEFORM) = 0,34
Materialia Utilizata: Cementum (PO42,5), Sabulum (sabulum normae ISO)
Tempus operis regulatur cum retardatore speciali "D300"
Mortarium rapidum durans, cui additum est BEFORM, praebet praestantem resistentiam contra rimas in aetate prima, comparatum ad mortaria quae adduntur cemento rapidum ordinario (cemento sulfoaluminato calcis: SAC).
Cautiones de Usu
Tempus operandi
Tempus operis variare potest secundum temperaturam ambientem, genus et dosim retardatoris, genus cementi, et partem cementi. Facite experimentum antea ut tempus operis confirmetis.
Additio nimia retardatoris causat duratio improba, quod ducit ad defectum partialis aut totalis durandi.
Aqua Constructionis
Utere aqua pura ex rubro pro constructione; vitare aquam fluminis vel alias fontes aquae quae possunt causare duratio improba.
Servatio Producti
Hoc prōductum magis humōrem absorbet quam cēmentum ōrdinārium. Post apertūram, eum eōdem diē utere aut in aliud, hermēticius clausum, continēns ad servandum trānsferre.
In locō siccō intus servāre, ut solīs directīs et pluviārum contactūs vitentur.
