Liquid 40% 50% Powder 98% polycarboxylate cement - AS1

Liquid 40% 50% Powder 98% polycarboxylate cement

1, POLYCARBOXYLATE SUPERPLASTICIZER AS1Usage Instruction:

A),AS1 is a safe and environmental friendly high efficiency superplasticizerfeaturing low blend dosage, high water reduction rate and fine cementadaptability without any influence upon the environment.

B),AS1 appears to be colorless transparent colloidal solution with mainhomogeneity indicators listed as follows:

2, AS1 Application Scope and Method:

A), Sincerely branAS1 mixed with concretes above C45 will result in a more comprehensive and economical effect. AS1 can also be applied in C45 below.

B),AS1 is applicable for ordinary concrete, high-strength and high performanceconcrete, and special concrete (anti-permeability, waterproof, crack resistance,anti-erosion, wear resistance etc.) preparation etc. for its high water reductionrate, good plasticity retention and strengthening effect.

C), The blend dosage range of AS1 is 0.20~0.80% (solution) of the weight ofcements or gel material. The regular blend dosage is 0.40~0.70% (solution).Since water reduction rate of concrete mixed with AS1 is relatively high, theconcrete slump is sensitive to water content, which shall be strictly controlledduring operation.

D), AS1 can be directly added into mixing water or the wet concrete alreadymixed with mixing water. It is not recommended to add (AS1) into dry concretemixture. Separate batcher and feeding tube are needed.

E), Adaptability of AS1 to most cements are satisfactory, but to some cements,problems such as low water reduction rate, highslump loss may appear.Besides, the fineness and storage time of cement may also influence theapplication effect of sincerely brand AS1. In this situation, solutions may be applied such asappropriately increase the dosage or formulate other retarding components, etc.

F), Compatibility problem exists in the formulation of sincerely brand AS1 and othersuperplasticizers. It is recommended that the necessary formulation experimentshall be conducted before application, so as to obtain the best effect.

G), With the application of AS1, air content of concrete is increased (usuallyby 3~5%). It is good for improving the workability and durability of concrete.Certain amount of defoamer may be added if the air content needs to bereduced.

H), AS1 is high-performance superplasticizer (Standard) liquid masterbatch. Bothseparationand formulation can be used. But it can not be formulated with Naphthalene Sulfonate (Sodium/Calcium). When the product is formulated, our company can offer relevant technical support in accordance with customers using condition.

3, Packing, transportation and storage:

A), Sincerely brand AS1 plastic drums are used for airtight packing to prevent leakage or evaporation. Tank car may be used for bulk packing in transportation.

B), It can be stored for 6 months under the temperature of 5~40°Cif the original packing is not removed. In particular situations when solution becomes turbid, it can be used again if the testing results fall within the established range after the expiration date.
