LonS-300 abides by GB8076-97, JC473-2001, and ASTMC494.
LonS-300 is water reducing, reinforcing and retarding, and its main components include common water-reducer, retarder, etc., combined with some special surfactants. It contains extremely low content of chlorine salt and sulphate, with no corrosive harm to reinforced steel bars and no adverse effect on concrete shrinkage. Since its composition contains slump retaining component, it has good adaptability to portland cement, and is widely used in cast-in-place concrete, pumping concrete, reinforced concrete and mass concrete projects. It is suitable to prepare C10-C30 concretes.
I、Performance
1、Nontoxic, odorless and incombustible.
2、Water reduction: If other conditions remain unchanged, with LonS-300 applied, the water reduction of the concrete reaches 12-18%; the strength and other properties are improved at the same time.
3、Plasticity: If other conditions remain unchanged, with LonS-300 applied, the concrete slump reaches above 18cm, construction performance of concrete improved greatly.
4、Retarding: LonS-300 is of certain retarding performance which can be adjusted according to customers’ requirements.
5、Air entraining: LonS-300 is capable of air entraining, reducing concrete bleeding rate and improving permeability, and is impact resistant.
II、Recommended Blend Dosage
Blend dosage range of LonS-300 in concrete is 1.5-2.5kg/100kg cementing material. Normally, 2.0kg/100kg cementing material is used. Before using this product, users should consider the local raw materials and construction conditions, and determine the optimal blend dosage through testing so as to ensure stability of concrete quality. Especially for the cement taking anhydrite and phosphogypsum as retarding components, experiment is extremely important.
III、Blend Method
Mix the measured LonS-300 with some mixing water, and blend the compound into the concrete; then add appropriate volume of mixing water into the concrete and mix them evenly.
IV、Packing and Storage
1、LonS-300 shall be packed in plastic drums, 200kg/drum; or tank car can be adopted in bulk packing.
2、LonS-300 shall be stored in sealed containers to prevent water leakage and water evaporation.
