Retarder

Cement retarder, an admixture capable of delaying the setting time of cement, can be applied to various types of concrete, including massive concrete, roller-compacted concrete, concrete constructed under hot climatic conditions, concrete poured over a large area, concrete designed to avoid cold joints, concrete requiring long-term storage or long-distance transportation, self-leveling vibration-free concrete, concrete constructed using slipform/drawform techniques, and other concretes where a delayed setting time is desired. It can influence the strength, shrinkage, and frost resistance durability of the hardened concrete

Polycarboxylate

This product boasts outstanding advantages such as high water reduction rate (up to over 40%), low dosage, minimal slump loss, significant enhancement effect, and environmental friendliness. It is widely used in the formulation of high-strength, high-performance concrete, self-compacting concrete, prefabricated components, as well as major projects such as high-speed railways, bridges, and super high-rise buildings
