More time to place. Less risk of cold joints.
Hot weather, long haul times, and large-volume placements all work against you. As ambient temperature rises or transit time extends, concrete stiffens faster — compressing your finishing window and increasing the risk of cold joints in multi-lift pours.
ATOM RET100 delays the initial hydration reaction, extending the workable life of the mix without compromising ultimate strength development. It's not just a set retarder — it also reduces water demand, so you gain workability without adding water and compromising your water-to-cement ratio.
The result: a wider finishing window, reduced cold joint risk, and the same long-term strength your spec demands. Order direct from our Pickering warehouse for GTA summer pours.
