PC-306 has been primarily developed for applications in the UHPC and other high strength concrete industries where the highest water reducing ratio and excellant early strength and enhanced strength performance and highest density required.
PC-306 is free from chlorides and complies with ASTM C494 Type A and F.
Conventional superplasticisers, such as those based on sulpunated melamine and naphthalene formaldehyde condensates, at the time of mixing, become absorbed onto the surface of the cement particles. This absorption takes place at a very early stage in the hydration process. The sulphonic groups of the polymer chains increase the navigate charge on the surface occurs by electrostatic repulsion.
PC-306 is differentiated from conventional superplasticisers in that it is based on a unique Polycarboxylic ether polymer with long lateral chains. This greatly improves cement dispersion. At the start of the mixing process the same electrostatic dispersion
occurs as described previously but the presence of the lateral chains, linked to the polymer backbone, generate a steric hindrance which stabilises the cement particles capacity to separate and disperse. This mechanism provides flowable concrete with greatly reduced water demand.
PC-306 production reaction temperature is fixed and can be controlled. It is not like other similar PCE,whose production temperature fluctuates in high range.
