Introduction
Long slump retention concrete uses additives is very advantageous for the preparation of high fluidity concrete, self-compacting concrete and water-faced concrete.
admixtures have the following effects in improving the performance of concrete:
(1)Long slump retention additives can be reduced, or the fluidity of concrete can be increased without increasing the water consumption.
(2) The setting time of concrete can be adjusted.
(3)Long slump retention concrete uses additives can reduce bleeding and segregation, improve workability and water resistance.
(4)Increase strength, increase frost resistance, impermeability, wear resistance, corrosion resistance.
