Accelerator masterbatch

Accelerator masterbatch Description: · The main technical performance: * 1, the use of this masterbatch accelerator complex (1: 3.5-4T) finished fast coagulation, viscosity, a small amount of springback, adjust a wide range of cement adaptability. 2, the initial setting time 2-4min Final setting 4-8min. 3, the content of 3-5% cement content is generally 4% cement ratio of 0.4. 4, the incorporation of this agent one day compressive strength of 8.8Mpa, 28-day strength can be maintained is not mixed with those of more than 80%. 5, cement setting time influenced by the temperature, 20 ℃ general temperature is 20 ℃ lower than the dosage may be increased. Application Techniques: 1, all kinds of accelerator adaptation problems exist on cement, cement used in construction must be suitability before use, to determine the optimal dosage. 2, the construction should be strictly controlled in the water-cement ratio between 0.3 to 0.5, water-cement ratio is too large to affect the results. 3, mixed with the concrete of the accelerator with the mix with dry spices with its stacking time is not more than two hours, otherwise, not only affects the accelerator effect, but will reduce the strength of sprayed concrete. 4, incorporating the present accelerator of concrete projects, should strengthen the early conservation to ensure the smooth progress of the hydration reaction to reduce lower on late strength. 5, cement stored for too long or poor construction shall be appropriate to increase the dosage. Packaging, transportation and storage 1. The product packed in woven bag lined with plastic film, the weight of 50 ± 0.5kg / bag. 2, may not rain, mainly moisture. 3, the product should be placed in ventilated dry warehouse, valid 180 days.
