MasterRheobuild 1033

High Range Water-Reducing Admixture for Concrete

Material Description

MasterRheobuild 1033 is a melamine sulphonate based high-range water reducing/superplasticizer admixture that improves the early and final strengths of concrete by imparting rheoplastic properties.

Areas of Application

MasterRheobuild 1033 is suitable for:

• Concrete where high plasticity, normal-setting characteristics, and accelerated strengths are desired

• Prestressed, precast, and ready-mixed concrete applications

• Civil and mining applications

Characteristics and Benefits

Plastic State:

• Controlled set times

• Cohesive and non-segregating

• Minimal bleed water

• Less dependence on consolidation energy

Hardened State:

• Higher early strengths than conventional high-range water reducers

• Increased ultimate compressive strength

• Higher modulus of elasticity

• Improved bond strength to steel

• Low permeability

• High durability

• Reduced shrinkage and creep

• Highly reliable in-place structural integrity

General Advantages:

• Job time and cost reduced through higher productivity rates and/or reduced labor

• Early strength allows accelerated construction methods, enabling completion ahead of schedule

• Engineering specification flexibility allows greater limits on concrete free-fall, lift heights, temperature, and potential economic mix adjustments
