If you look at slide number 7 in yesterdays presso titled “New Concrete Application” carefully compare the five bar charts after 14 days of curing with the five bar charts after 21 days of curing. Hopefully you will see that after 14 days the strength of the three concrete samples with ADN’s additive (the three bars towards the right hand side) are all similar at around 40Mpa (reading off the vertical axis). Now compare with the strength of the two control samples after 21 days. One control sample looks to be around the 40 Mpa while the other appears to be about 37-38 Mpa.

The point I am making is that the concrete samples using our additive all achieve similar (or better) strength after only 14 days of curing to the control samples which have cured for 21 days. The gain of seven days in curing time can be seen again if you compare the concrete strengths between 21 days and 28 days of curing.

This significant gain of seven days to reach acceptable strength if recognized by the authorities could be worth far more than any reduction in the cost of manufacturing the concrete and create huge demand in the industry. For a 10 story building it could conceivably allow props/formwork for each suspended concrete floor to be removed a week earlier and reduce the overall build time by around 10 weeks saving the builder a huge amount of outlay on the hire of everything on site. Every multistory building built in Australia (and possibly worldwide) could be looking to use this additive.
