Product Description
UNF-5A Naphthalene pure highly effective retarding & water-reducing admixtures for concrete has the characteristics of retarding, super-plasticized, water-reducing, less loss of slump. It is very effective concrete admixture to adopt in high temperature area.
----------------------------------------------------------------------------------------------------------------------------
Main Properties and Characteristics
Excellent effect of retarding: It can be used in retarding the setting of concrete for 2 hours
to 36hours, and initial setting and ultimate hardening almost delay the same long time
corresponding, so that its convenient for conveying at long distance.
With the water-reducing rate of 12%-25%, it can improve the floating, permeation-proofing ability , and the workability of concrete, concrete compression resistant, and other physical mechanics will be also gained.
Reduces cement dosage by 12%-25% without altering compression strength and slump.
Good for many applications: Portland cement, ordinary Portland cement, Portland fly-ash cement , Portland pozzolan cement and Portland blast Furnace-slag cement.

Typical performance
UNF-5A improves initial and ultimate strengths. It also gets less loss of slump and improves
workability of the concrete more than traditional concrete admixture. The lower content of
Na2SO4, in the admixture, will lead to meet the requirement of the special cement concrete
engineering project in the coastland and high saline-alkali area.
