MNC-N Accelerator

 

APPLICATION

It can be applied to early-strength concrete construction projects that are launched in winter,at ambient or low temperature.Recovery period can be cut shor.As the result,efficiency will be accelerated and modulus & site will be fully utilized.Suitable for construction of pre-cast site and countryside house erection.

PROPERTIES,FEATURES & CHARACTERISTICS

1. As accelerator and strength enhancer,it is practical and easy to handle.

2. Appearance:Grey powdery agent.Non-poisonous,odorless,non-flammable,and non-corrosive to steel bars.Intended for the acceleration of treminal strength of concrete.

3. Preliminary strength of concrete can be apparently accelerated when it is added at 2.5% in winter.The strength increase exceeds 60%,45%,25% and 10% on the 1 st day,3 rd day ,7 th day and 28 th day respectively.

Note:Standard Blend Dosage:2.1%

RECOMMENDED BLEND DOSAGE

The blend dosage normally ranges between 2 .1 %.The standard blend dosage is established at 2.1%(as cement amount).

DIRECTIONS

1. The powdery agent can be agitated together with cement.Accurate measurement is essential.

2. A 30-second agitation is required to achieve to achieve good homogeneity.

PACKGING,TRANSPORTATION AND STORAGE

1. Woven fabric bag with plastic liner.Net weight: 25kg ±0.13 or 50kg ± 0.25.

2. Cautions should be taken to prevent from being torn by sharp-ended objects while packages are transferred or delivered.In case of humidity contamination,re-use is allowed after drying and crushing.

3. It should be stored in a deicated warehouse that is well-ventilated and dry.It remains effective in two years.At the expiration,re-use is allowed if the testing results fall within the established range.
