significant decrease of cment permeability
achieving very high final resistence Physicological increase and efficiency of fresh
concrete probability of manufacturing self compressivecement improvement in pumping capaility and cement finish improvement in cement properties and decreasing the alkaline properrties of cement increasing cement compression and long-term durability of cement decreasing permeability, increasing compression and long-term durability of cement slamp maintenance more than 60 minutes with achieving normal setting time ۱۰-۱۵% decrease in the ration of water to cement in low use amount high improvement of cement quality with decrease of water to cement 33%
۱۲۵ masterGEL is provided in 25 kg containers
physical state: concentrated slurry color: dark grey special weight: @ 25°C 1.25 – 1.35 pH: 5.0 – 7.0 choloride ion: it does not have *the mentioned data are achieved based on the final laboratory controlled tests
Although there is no specific standard for this product, this product can be evaluated based on the following standards. ASTM C 494, EN 934, ISIRI 2930
the proposed dose of this product is 1-2.5 weight percent of cement
the possibility of the consumption dose change from the specified range for the projects with special workshop conditions, only with the permission of Partak concrete technology experts.
the best method of use: adding 125 masterGEL after adding stone materials and cement and 80% of water mixture to cement. Also, in cases where the time interval between manufacturing and pouring of concrete is long, it is suggested that the gel product of 125 masterGEL can be added in two stages that a part is batching and another part as dossage is added about 3 minutes before use in the mixer truck. The required time for complete mixing of the gel is 3 to 5 minutes.
۱۲۵ masterGEL is compatible with all tips of portland cement and slag if it is necessary to use several additive material, it should be contacted to Partak cement technology section
storage and shelf life
۱۲۵ masterGEL is maintaned in closed packaging and away from direct rays of sun and ice situation.
in the case of above situation, the useful life of the product is 12 months from the date of production.
health and safety
there is not need for special actions but for observing safty actions, it is better to use protection gloves and eye glasses. In case of direct contact with skin or eyes, rinse immediately with water and see a doctor.
