high range set retarding water-reducing admixture, which is combined of the naphthalene series and the amount of high-performance water-reducing retarder, stabilizer, reinforcing admixture, has a high efficiency water-reducing, retarding in the initial setting and early strength in final setting, late-enhanced, small slump loss etc. it is the perfect concrete admixtures for the preparation of high-performance, high-strength concrete, mass concrete and long-distance transport of concrete. The product can be produced powder and liquid, to meet different engineering requirements.
- Dosage range: Powder dosage amounts to 0.5-1.2% of total cementitious material, the liquid dosage amounts to 1.5-3% of total cementitious material, reducing-water rate is 15-25%.
- A slight increase in air content is beneficial and without adverse effects on the concrete.
- The product has the retarding plasticity, small slump loss, which is extremely beneficial to the transport and to pouring of concrete.
- The product has a retardation 1-3h, it can also be adjusted for setting time basing on the user's demand. It has not affected the strength growth of concrete.
- The compressive strength of concrete, flexural, tensile, impermeability and durability are significantly improved and enhanced.
- the product has the broader applicability of cement, which is the preferred preparation of concrete.
