MasterRheobuild 1000

High Range Water-Reducing and Hardening Accelerator Admixture for Concrete
EN - 934 - 2 : T 3.1/3.2

Material Description

MasterRheobuild 1000 is a naphthalene sulphonate based high range water reducing/superplasticizer admixture that improves the early and final strengths of concrete by giving Rheoplastic property.

Areas of Application

• 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

• Less dependence on consolidation energy

• Early strength allows for accelerated construction methods, resulting in completion dates ahead of schedule

• Engineering specification changes can allow for greater limits on the free-fall of concrete, lift heights, concrete temperatures and potential economic mixture adjustments

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

Plastic State:

• Controlled set times

• Cohesive and non-segregating

• Minimal bleed water

Hardened State:

• Higher earlier strengths than can be achieved with 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
