RB-MS375 for concrete is available 25 kg packages.
The optimum dosage of Microsilica Gel RB-MS375 can be determined by trials in the site. Depending on concrete mix design (concrete type, workability, compressive strength, sizes and types of aggregates, cement content, water/cement ratio, ambient temperature and concreting conditions), a dosage of between 2 and 7 percent by weight of cement is recommended. For use with other range of dosage, contact RBBCO Technical Services Department.
DIRECTION FOR USE
Add 2% to 7% of total cement, RB-MS375 to concrete. RB- MS375 gel can be added at the time of concrete making in batching or after concrete making in truck mixer. If RB-MS375 gel is added in to truck mixer, be sure of complete mixture of gel and concrete. According to experimental results RB-MS375 gel should be mixed in truck mixer for 2-5 minutes. To get the best result, use RB-MS375 in two stages. One part of gel into batching and another part as a reminder dose should be added to truck mixer 5 minutes before using.
RB-MS375 gel can be added to concrete in two ways:
RB-MS375 gel could be added to ready-mix concrete before placing concrete. RB-MS375 microsilica could be added to a part or whole of concrete mixing water then added to the concrete mix.
