1,feature
- It has high water reducing rate, low dosage of high water reducing rate can reach 30 percent, increase dosage, water reducing rate can reach more than 40%;
- low dosage, dosage of gelled material dosage of 0.5 ~ 1.2% (SC20 %);
- slump and low slump loss, fresh concrete condition to keep good performance, no slump loss in two hours, especially suitable for the preparation of high performance, high strength pumped concrete, and setting time can meet the needs of work
- strong water retention performance, make fresh concrete has good adhesiveness, parcels, difficult to segregation, exudation, and make fresh concrete has good homogeneity workability;

has obvious thixotropic performance, especially in a small slump more obvious

High strengthen: high strength growth, especially in 3 d, 7 d strength increased more obviously, the dosage of cement under the condition of the same as the slump, early strength increased by more than 70%, 28 days strength increased by more than 40%;
concrete hardening and high durability: concrete were high strength, good volume stability, impermeability and freeze resistance, corrosion resistance and carbonation resistance;
after concrete hardening, bubble less appearance, color uniformity is good, the concrete structure is more compact, more excellent durability.
can raise the replace quantity of fly ash, and reduce cost, reduce the early beginning of concrete hydration heat, make the concrete durability is better;
wide adaptability of Portland cement, ordinary Portland cement, slag Portland cement, fly ash,
good workability of concrete: fresh concrete workability is good, no segregation, no bleeding, good adhesiveness, air content is moderate, is suitable for pumping;
the product unique polymer structure is difficult to compatible with other water reducing agent, naphthalene series water reducing agent, in particular, so it is forbidden to mixed with naphthalene series water reducing agent;
green environmental protection: this product is a non-toxic, no corrosive liquid, the steel bar corrosion, environmental pollution-free;
this product according to the different divided into the early strength of the blending components, standard gentle setting, etc.;
different concrete ages than compressive strength, shrinkage ratio and other indexes satisfy GB8076-2008 "concrete admixture" regulation of indicators.

Mainly applicable scope

1, the preparation of high performance, high strength, high strength concrete, such as airports, high-speed rail, nuclear power, water conservancy and hydropower engineering, subway, Bridges, highways, harbor wharf, military facilities, and other key state large and engineering;

2, high liquidity, self-compacting concrete, solve common concrete pouring of self-compacting concrete technical problems;

3, to produce various high strength, good work performance, hardening performance and excellent durable performance requirements of high performance concrete, suitable for all kinds of civil and commercial concrete mixing station.

Use and attention

1, conventional dosage range of 0.25 ~ 0.8% (SC20 %), the actual content need to be confirmed according to the design of proportion of concrete strength grade after the test;

Batch test to ensure the concrete quality.

3, can use with a variety of early strength components, retarded components, defoaming agent, air-entraining agent and water reducing agent, such as wood sodium compound with use, but can not be used with naphthalene series water reducing agent;

4, this product does not belong to the terminal customers to use, suggested that the user through the test before use and distribution of technology to determine the methods and conditions on the use of the products.

Packaging, transportation and storage

1, this product is liquid, barrel seal to avoid rain and sundry into or moisture to evaporate run dry;

2, storage, transport process leakage, prevent sun, anti high temperature;

3, shelf life is 6 months, expire inspection qualified rear can use.

4, this product is no alkali liquid, non-toxic, non-corrosive, non-polluting products to the environment, but do not eat;

5, when contact with eyes, rinse as soon as possible.
