3Performance and use
1、 Mixes the quantity for the cement weight 0.5 - 1.2%, efficiency of reduces water can be reach 12 - 25%.
2、 In the same cement situation, mixes into FDN to be possible initial to make the concrete slump to enhance above 10cm.
3、 When is suitable mixes the quantity, may cause the intensity of mortar and concrete enhances 40 - 80% for one day or three day , 28 days intensities enhances 20 - 60%, the long-term intensity also has the corresponding enhancement.
4、 When the concrete intensity and slump basic is same, may compare does not mix reduces water agent the concrete reduction cement content 10- 25%.
5、 Mixes into FDN to be possible greatly to improve the amalgamation of concrete, improves and enhances the concrete component each mechanics performance, causes the component the resistivity, the elasticity coefficient and the long-term intensity all have the corresponding enhancement.
6、 FDN is very broad to the concrete project applicable scope, but has the difference to the different cement compatibility.
