About the product

UltraCrete RSC: Rapid Setting Cement

Ultracrete RSC Rapid Set Cement, when mixed with aggregates, produces a fast setting, high strength mortar. It is ideal for use on cable box floors, road crossings, sign and camera bases, with the benefit for highways contractors that roads or pathways can be opened to traffic and pedestrians in just 1 hour.

Ultracrete RSC is supplied in 20kg reinforced paper bags and contains a mix of approved chemical additives, which accelerate the process of hardening once the product is placed in situ. When mixed with sand or sand/aggregates, RSC can be laid from 10mm-250mm in just one pass. Ultracrete RSC does not contain chloride, metallic aluminium, iron or carbon, which eliminates the problems associated with corrosion and or staining, meaning a clean, durable and lasting repair.

RSC Rapid Setting Cement can be mixed by hand or with a freefall mixer, the mixing proportions will ultimately vary depending on the design mix, to accommodate the strength needed and speed of set that is required for the repair. As a rough guide, the maximum size of the aggregate should not exceed one third of the thickness of the repair at its thinnest point. If RSC cement is bulked out with sand, the sand needs to be well graded, clean and sharp. However if bulking out with a coarse aggregate, you must ensure that it is clean and well-graded down from maximum.

Siliceous stone, granite or basalt chippings may be used for all applications. Please note that hard limestone should not be used in areas subject to acid attack.
