Highly effective setretarding concrete superplasticizers, water reducing superplasticizers
SUMIX 480 highly effective set retarding concrete superplasticizer is a synthetic admixture based on beta-naphthalene sulphonate formaldehyde condensates and reactive high polymer. It’s in particular adaptable to water reducing, retardant and reinforce. The product can be widely used in the concrete projects which required water-reducing, retardant, low hydration heat, high durability.
Main Technical Performance Index and properties:
High water reduction
SUMIX 480 has obvious water reducing effect for concrete with the standard test methods, the water reduction of concrete with SUMIX 480 is above 20%, This effect is more evident for high fluidity concrete which has water reduction up to 31.8%.
High strengthening effect
It has a very good strengthening effect. Comparing with ordinary concrete, the strength of concrete with SUMIX at the age of 28 days can increase 35%~60%, at the age of 90 days can increase 20%.
Outstanding retarding effect
The addition of SUMIX 480 can increase the initial set time of concrete by about 8 hours furthermore can increase about 10 hours in different projects, which provides abolishing or lessening construction joints.
Concrete with SUMIX 480 has high ability against water bleeding and segregation; furthermore, using SUMIX 480 can reduce the blockage in the course of concrete pumping and make the concrete easier to pump.
Low hydration heat
Comparing with those of pure cement paste, the peak value of the hydration heating of the cement paste with SUMIX 480 is much lower, moreover, the time when the peak of hydration heating arousing is delayed 24h. Moreover, the hydration heat of the SUMIX 480 cement paste at early age is only 1/7 of that of pure cement pastes.
This product is adapt to different types of cement, and particularly match with admixtures such as air entraining agent, and mineral aids such as fly ash. Highly consistent quality.
The addition of SUMIX 480 can effectively improve the durability indexes of concrete, the ability of concrete anti-carbonisation with SUMIX 480 is 1.5~2.5 times than ordinary concrete, and resist the corrosion of steel.
Sumix 480 is added into concrete and mortar mixes in condition of water solution of working concentration in the amount 0.8 - 2.3% of dry substance from cement mass.
