GK-4A Retarding high efficiency water reducer

GK-4A’s main material is naphthalene high efficiency water reducer, as well as compounded from retarding agent, plasticizing agent and some other surfactants. Its advantages are: high ratio of water reducing, long working time, and good plasticizing performance. It meets special demands of projects, needing to slow the concrete setting time: such as vast volume of concrete, roller compacted concrete and construction in high temperature.

Basic mechanical design feature
a: the powder of this product is 0.7-1.5%,the liquid dosage is 2-3%, water reducing ratio ≥12%
b: concrete with this product can prolong its setting time 8-10 hour under 30°C

c: with this product, the strength of concrete increased obviously:7d≥130%, 28d≥120%

d: good adaptability ; ameliorating the concrete workability, enhancing the concrete anti-permeability, anti-freezing and durability.

e: slow down the hydration and hardening process of cement; reducing heat of hydration and temperature stress; effectively avoid concrete crack.

f: chlorine free, low alkali, well adapt to different cements

Tips
a: adding this agent and cement into mixer at the same time and prolonging the mixing time 30-60s

b: doing matching experiment if cement as regulator of anhydrite and industrial waste

c: weighting exactly before using

Package, storage
a: woven bag lined with plastic film packaging, 25kg/bag
b: avoiding got damp, keeping in cool, dry ventilated storage,
