Sika® ViscoCrete® RM-115 SA

HIGH RANGE WATER-REDUCING  ADMIXTURE FOR CONCRETE

Sika® ViscoCrete® RM-115 SA is a polycarboxylate
based superplasticizer developed particularly for use
in ready mixed concrete to give extended slump retention and high strength development of high specification grade concrete mixes. Sika® ViscoCrete® RM-115 SA is suitable for use in concrete mixes incorporating  pozzolanic materials such as GGBS, PFA and microsilica. Suitable for use in hot and tropical climatic conditions.

Sika® ViscoCrete® RM-115 SA acts by surface absorption on the cement particles producing steric hindrance and electrostatic repulsion between cement particles which results in higher dispersion, flow and retention. Sika® ViscoCrete® RM-115 SA provides the following beneficial properties:
  • Powerful plasticising action Production of workable concrete at low water binder ratio
  • Improved shrinkage and creep characteristics
  • Excellent flowability resulting in minimal placing and compacting efforts
  • Slower rate of carbonation ingress
  • Cost effective, structurally economical concrete
  • Higher ultimate strengths allows greater flexibility for engineers to design durable concrete
  • Reduced surface defects so improving aesthetic appearance
  • Durable concrete, doesn't contain chlorides or other steel corrosion promoting ingredients

Usage

Sika® ViscoCrete® RM-115 SA is mainly used for the following applications: 
  • Production of site mixed and ready-mix concrete during hot weather production of concrete with extended transportation or placing times
  • Concrete requiring workability retention
  • Concrete with low water binder ratio
  • Concrete placing in congested steel reinforcement
  • Production of high flowable and self-compacting concrete (SCC)
  • Slim elements requiring a high standard of surface finish
  • High performance durable concrete

Technical Information

Concreting guidance

The standard rules of good concreting practice for production and placing must be observed when using Sika® ViscoCrete® RM-115 SA in concrete. Refer to relevant standards. Fresh concrete must be cured properly especially at high temperatures in order to prevent plastic and drying shrinkage. Use Sika® Antisol® products as a curing agent or apply wet hessian.

Application

Application Information

Compatibility

Sika® ViscoCrete® RM-115 SA is suitable for mixes containing all types of cement and supplementary cementitious materials such as: Microsilica (Silica Fume), Fly Ash (PFA), GGBS (Ground Granulated Blast Furnace Slag) and the following Sika products:
▪ SikaPump®
▪ Sika® FerroGard®
▪ SikaFume®
▪ SikaFiber®
▪ Sika® Aer
▪ Sika® Stabilizer
▪ SikaControl®

Sika® ViscoCrete® RM-115 SA can be used with air-entraining admixtures, provided they meet ASTM, AASHTO CRG specifications. We recommend to perform trial mixes to establish the required performance when combining Sika® ViscoCrete® RM-115 SAwith the above products or other admixtures. Please consult our Sika Technical Department for further assistance.

Dispensing

Sika® ViscoCrete® RM-115 SA is added to the gauging water or simultaneously poured with it into the concrete mixer at the batching plant. Do not add Sika® ViscoCrete® RM-115 SA directly to the dry mix. For optimum utilization of its high water reduction property, we recommend thorough mixing at a minimal wet mixing time of 60 seconds.The addition of the remaining gauging water (to fine tune concrete consistency) may only be started after two-thirds of the wet mixing time to avoid surplus water in the concrete.
Consumption

Recommended dosage

0.5 L to 2.0 L per 100 kg of total binder. Higher dosages by weight of binder can be used depending on the mix design, raw materials, climatic conditions and concrete requirements. Trial mixes must be performed to establish the exact dosage as per the project requirements.
