RECOMMENDED USES
- Precast/pre-stress concrete
- Site batched concrete
- Pumped concrete
- Wet Shotcrete Mixes
- Concrete containing microsilca/ metakaolin
- Concreting in low temperatures
- High performance grouts/tunnel backfills
- Cementitious injection suspensions
- Suitable for Concrete Piles
FEATURES AND BENEFITS
- Controlled set times
- Produces flowable concrete at reduced W/C ratios
- High early strengths – Accelerated construction
- Least dependence on consolidation energy
- Improved bond strength to concrete
- Higher modulus of elasticity
- Increased compressive, tensile and flexural strengths as a benefit of its water reducing action
- Reduced permeability – Improved durability
- Reduced thermal peaks – reduced cracking
- Highly reliable in-place structural integrity
APPLICATION
MasterRheobuild 1100 is a ready-to-use liquid which is dispensed into the concrete together with the mixing water. The plasticising effect and water reduction are higher if the admixture is added to the damp concrete after 50 to 70% of the mixing water has been added. The addition of MasterRheobuild 1100 to dry aggregate or cement is not recommended. When using MasterRheobuild 1100 to produce flowing concrete at site using ready mix trucks, it can be added to the concrete via the feed hopper at the rear of the truck. Mix before discharge for 5 minutes at 10 rpm to produce a fully homogenous mix.
