Cas No. :91-20-3
Specs:93% Main Technical Performances 1. Type 100 is divided into powder admixture and liquid admixture. The power admixture is chocolate brown; And the liquid admixture is brownish black. It has no toxicity or pollution, and is not inflammable. 2. The content of type 100 powder admixture is 0.5~1.0% of cementing material; And that of liquid admixture is 1200~2500ml/100kg cementing material; The water consumption for mixture can be reduced 15~25%; There is obvious early strength effect; The strength can be increased 50~80% in one day and three days; 30~60% in seven days; And more than 20~40% in 28 days. 3. Under the same water-cement ratio, the initial slump of concrete can be improved more than 10cm, which makes great increase on fluidity. 4. Under the condition of basically unchanged compressive strength of concrete, the cement consumption can be reduced 10~20% when mixing this product. For example: When selecting and using Evergreen P. 042.5-level cement, natural medium sand of 2.81 fineness modulus, the artificial gravels of Φ 5~31.5mm continuous graduation and compressive strength of not less than 105Mpa, and drinking water, to prepare C50-level high-strength concrete, such as the concrete of box girders of some bridge; (Only for Reference). 5. Type 100 water reducing admixture can greatly improve the workability of concrete and various physical performances of concrete components. 6. Type 100 water reducing admixture has good adaptability to cement; And also can be mixed with concrete admixture of other types in conformity with national standards. 7. Type 100 low-chloride super high-efficiency water reducing admixture has low content of chloride, and is the first choice of admixture compound factory of concrete. Scope of Application Type 100 water reducing admixture is widely applied into concrete projects, especially adapting to the following concrete project: Foundation concrete, mass concrete, flowing concrete, self compacting concrete, pumped concrete, steam-curing concrete, natural curing precast concrete, reinforced concrete and pre-stressed concrete, and high-strength concrete. Usage 1. Addition: The addition of type 100 admixture is 0.5~1.0%, the general additon is 0.75% (calculated as the percentage of dry powder to cement in weight). When preparing low-grade concrete or adopting slag cement, select and use the amount of 0.4~0.6% to save cement and improve economic benefits; While preparing high-grade and pre-stressed concrete, select and use the amount of 0.75~1.0%. |
