    Sikament® RB 1100 (formerly known as MasterRheobuild® 1100) - High range water reducing, superplasticiser for rheoplastic concretes

    How does MasterRheobuild 1100 work?

    MasterRheobuild 1100 is composed of synthetic polymers specially designed to impart rheoplastic qualities to concrete. A rheoplastic concrete is a fluid concrete with a slump of at least 200 mm, easily flowing, but at the same time free from segregation and having the same water/cement ratio as that of a no-slump concrete (25 mm) with admixture. MasterRheobuild 1100 is chloride free.

    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

    What makes MasterRheobuild 1100 a unique solution?

    MasterRheobuild 1100 helps to procude high strength concrete with optimum cement and water content, mainly for precast concrete. It also improves properties of concrete in plastic state to improve ease of placement.

    What are the features and benefits of MasterRheobuild 1100?

    • Controlled set times
    • Produces flowable concrete at reduced W/C
    • 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
