Sep 09, 2014· CSA Cement is the perfect addition for mix designs that need to achieve high strengths quickly – as strong as 3,000 PSI in 90 minutes and an initial set time as fast as 20 minutes.
Although portland cement is less expensive on a first-cost basis than rapid-hardening hydraulic cement, its durability, rapid cure time, reduced shrinkage, and resistance to chemical attack outweigh the cost differentials, especially when the cost of time is added to the equation.
The concrete curing process is both costly and time consuming, especially in the precast industry where it is one of the key challenges. fdu Betonwerke, one of the largest manufacturer of precast concrete elements in Germany relies on Master X-Seed, the unique hardening accelerator to halve hardening times, to lower energy costs and to reduce CO2 emissions.
Of course, decorative concrete contractors also have other techniques for accelerating concrete besides adding an accelerator. Using cement that promotes high early strength will work. So will adding a water reducer, curing at higher temperatures, and lowering the water-cement ratio by putting more cement into the concrete.
Curing plays an important role on strength development and durability of concrete. Curing takes place immediately after concrete placing and finishing, and involves maintenance of desired moisture and temperature conditions, both at depth and near the surface, for extended periods of time.
Jun 08, 2017· fdu Betonwerke has reduced the curing time in the production of precast concrete elements from twelve to six hours* – with the revolutionary concrete additive Master X-Seed.

Edit Article How to Cure Concrete. Curing concrete is the term used for stopping freshly poured concrete from drying out too quickly. This is done because concrete, if left to dry out of its own accord, will not develop the full bond between all of its ingredients.
It gives an added sealing protection for the concrete. Some curing and sealing products can be expensive as they are designed and meant for curing only. The time it takes to cure the concrete surface. Curing compounds are designed to last for 28 days. Various curing and sealing products remain on the surface for a longer period of time.
Fast track construction and precast concrete have resulted in more demand for very high early-strength specialist products. AfriSam's Rapid Hard Cement is an early-strength specialist cement which offers consistent, superior performance in all applications where quick mould turn-around or formwork stripping times are required.
For block, paver, precast, prestress, pipe or cast stone production, accelerated concrete curing systems can help achieve notable reduction in carbon-dioxide emissions by allowing significant SCM substitution for cement. Curing with heat and moisture is less expensive than overdosing a concrete mix with cement to achieve early strengths.
Inadequate curing has less of a negative effect on thicker, steel-reinforced concrete, since this type of concrete often spends more time curing in the mold and …
