High Strength and Fast Setting Concrete
DESCRIPTION
Deltacon QS is a ready to use two component fast setting and hardening concrete. It is only requires the addition of clean water in site to produce a highly consistent, free – flowing and high performance repair material. Part A consists of a high quality portland cement, sand and additives, packed as the powder component. Part B consists of well graded aggregates.
USES
Deltacon QS is suitable for applications where a fast – setting general purpose concrete is desirable. Areas can be applied such as concrete roads, runways, toll road, factory floors, and areas where a traffic requires fast return to service..
ADVANTAGES
• Acceleration of strength and hardening
• Smooth surface due to self compacting
• Chloride free
• Can be applied up to 12 cm thickness and for more thickness can be done layer by layer.
INSTRUCTION FOR USE
Deltacrete strongly suggest that be application of this material can only be executed by experienced and competent applicator as authorized by Deltacrete.
Surface Preparation
Surface must be clean and sound. Remove all deteriorated concrete, dust, dirt, oil, grease, and other bond – inhibiting materials. If the area wavy, level area before application.
Mixing
Use hand mixer or high speed mixer for best result. Mix 4.4 litres of clean water and partial part B stir only short time. Add 25 kg bag of Deltacon QS and partial part B, mix until the concrete saturated around 5 minutes to achieve desired consistency. If the material becomes difficult to mix, add small amounts of water and continue to mix and sure all material is uniformly mixed.
Placing & Curing
Apply Deltacon QS according to good concreting practice.
Apply Deltacon SB1 as curing agent then put the wet sack on top of Deltacon QS.
The application can be trafficked after 4 hours.
Storage
Deltacon QS has a shelf life of 12 months if kept in a dry store in sealed bags.
