POZZOLITH 400Ri
Polymer admixture for improving concrete DESCRIPTION
Pozzolith 400Ri is a ready-to-use liquid admixture for making better, more uniform and more predictable high quality concrete. It retards the setting time to facilitate placing and finishing. Concrete meeting architectural, structural and construction requirements is obtained more dependably and economically with Pozzolith 400Ri. Pozzolith 400Ri meets and exceeds AS1478.1-2000 type WRRe admixture requirements.
RECOMMENDED FOR
Pozzolith 400Ri admixture is recommended for use in all types of concrete where retardation of set and improved performance, particularly improved pumpability are required or desired. Pozzolith 400Ri admixture improves pumped concrete, shotcrete (wet mix) and conventionally placed concrete; it also improves plain, reinforced, precast, prestressed, lightweight or standard concrete. It can be used in white or coloured concrete. Pozzolith 400Ri can be used with air-entraining agents approved under AS 1478 Specifications when air-entrained concrete is specified or desired. While Pozzolith 400Ri entrains negligible air, it improves the efficiency of most air-entraining admixtures and will generally result in the need for less air-entraining admixture. BASF’s approved air-entraining admixture Micro-Air is recommended for use with Pozzolith 400Ri admixture when air-entrained concrete is specified or desired. When used in conjunction with another admixture each admixture must be dispensed separately into the mix.
FEATURES AND BENEFITS
Pozzolith 400Ri admixture aids in the production of concrete with these special qualities. • mild to extended retardation - depending on
dosage • greater pumpability • superior finishing characteristics for slabwork and
off-form surfaces • reduced water content for a given consistency • increased strength - compressive, flexural and
bond of concrete to steel • greater economy in a mix designed for a given
strength, slump and air content • minimum cracking • easier placement - economy in placement • greater durability • reduced segregation, particularly in lean mixes and
high slump concrete • slipformed concrete
QUANTITY TO USE
Pozzolith 400Ri is used at the rate of 250 to 400ml per 100kg cement. Similar dose rates may be used with blended cements.
RATE OF HARDENING
The temperature of the concrete mix and the ambient temperature (forms, earth, reinforcement, air, etc.) affect the rate of hardening of the concrete. At higher temperatures concrete hardens more rapidly and may impose problems with placing and finishing of concrete. By varying the dosage of Pozzolith 400Ri, concrete with a more desirable rate of hardening characteristic can be obtained. Since setting time is also influenced by the chemical and physical composition of the basic ingredients of the concrete, trial mixes should be made with the actual materials approximating job conditions to determine the dosage required for a given degree of retardation.
COMPRESSIVE STRENGTH
In comparison to plain concrete, a mix containing Pozzolith 400Ri develops higher early and ultimate strengths, exceeding the strength requirements of AS 1478.1-2000.
PACKAGING
Pozzolith 400Ri is supplied in 205 litre sealed drums and bulk delivery. For additional information on Pozzolith 400Ri and its use in developing a concrete mix with special performance characteristics, contact your local BASF Construction Chemicals technical representative.

RHEOBUILD® 1000
High range, water reducing, superplasticising admixture DESCRIPTION PERFORMANCE (As an High Range Water Reducer)
Rheobuild 1000 is a strength enhancing, superplasticising, high range, water reducing admixture formulated to produce rheoplastic concrete.
Example of the influence of Rheobuild 1000 on concrete compressive strength when dosed at 1000mls/100kg of cement.
Rheoplastic concrete is fluid concrete with a slump value of at least 200mm, easily flowing but at the same time free from segregation, and having the same water/cement ratio as that of no-slump concrete (25mm) without admixture. Rheobuild 1000 is a ready-to-use, chloride free, liquid admixture which meets ASTM C 494 requirements for types A and F admixtures, AS 1478 Type HWR.
RECOMMENDED FOR
• all types of premixed concrete where high water reduction or flowing properties are required
• industrial precast concrete • placement in cold weather Aggregate max. size = 20mm Cement content = 350kg/m³ Rheobuild 1000 has been used successfully in: Steam curing for 6 hours • pillars and footings 1 hour for preliminary curing at 20°C • prestressed elements Heating from 20 - 60°C over 1 hour • long distance, vertical or horizontal pumping Steam Curing at 60°C for 3 hours, cooling to 20°C in 1 hour.
• pavements • tunnel linings
PERFORMANCE (As a Superplasticiser) • partition walls • bridge girders • precasting systems
The addition of Rheobuild 1000 allows mixing water to be reduced considerably and concrete strength to be accelerated significantly, particularly at early stages. Rheobuild 1000 provides high quality, rheoplastic, non-segregating concrete with:- • shorter placing times • reduced steam and ambient temperature curing • increased strength at early ages • high reliability • high ultimate strength • impermeability
Aggregate maximum size = 20mm • durability Cementitious Content = 350kg/m³ • dimensional stability Initial slump = 40mm • high elastic modulus Temperature = 23°C • low shrinkage and creep
RHEOBUILD® 1000
DOSAGE
Rheobuild 1000 is normally dosed at 800 ± 200mls per 100kg of cementitious material. Other dosages may be used depending on the mix design of the concrete and ambient conditions. The actual dose depends on the degree of water reduction or flow required. Above 1000mls per 100kg cementitious material, extended retardation may be experienced.
WORKABILITY
Rheobuild 1000 can maintain the workability of fresh concrete for a pre-determined time. The precise workability duration depends on temperature, types of cement and aggregates, transport and dosage of admixture. Higher dosages provide higher duration of workability of fresh concrete.
DISPENSING
Rheobuild 1000 can be added at the batch plant or on site. When adding at the batch plant, delay addition until the cement has been thoroughly wetted and at least 75% of the water has been added. When introduced on site, mix for further 2 minutes after addition.
COMPATABILITY
Rheobuild 1000 is compatible with both water-reducers and air-entraining agents approved under SAA, SANZ and ASTM specifications when used in concrete, but must be dispensed separately into the concrete mix. Rheobuild 1000 should only be used in conjunction with water-reducing admixtures after specific test information is available at the dose rates proposed, otherwise extended retardation could result. Rheobuild 1000 is not compatible with admixtures based on polycarboxylate technology, such as Glenium 27 or Rheocrete UW450.
PACKAGING
Rheobuild 1000 is supplied in 205 litre sealed drums and bulk delivery. For additional information on Rheobuild 1000 and its use in developing a concrete mix with special performance characteristics, contact your local Master Builders Technologies field representative.
