Retarding plasticising admixtures not only delay the setting of the cement but are also efficient plasticising water-reducers. Most commercially available retarders are of this type. Retarding plasticisers are used to give workability retention to the concrete delay the
admixtures can be very beneficial in producing high strength concrete with a low water-cement ratio. The American Society of Testing and Materials ASTM specification C494 covers eight 8 types of chemical admixtures Type A Water-reducing admixtures Type B Retarding admixtures Type C Accelerating admixtures

Nov 03 2020 ASTM Categories - Concrete Admixtures. ASTM C494 specifies the requirements for seven chemical admixture types. They are Type A Water-reducing admixtures. Type B Retarding admixtures. Type C Accelerating admixtures. Type D Water-reducing and retarding admixtures. Type E Water-reducing and accelerating admixtures.
Barrier One Concrete Admixtures is the premier concrete admixture provider in the United States. Because moisture easily travels through untreated concrete the costs of adhesion failure and topically applied moisture mitigation can quickly eat into the profits of even the largest construction firms.

A concrete set retarder is an indispensable additive for continuous casting pumping mass concrete construction and other construction processes. The application of concrete retarding agent is quite extensive. They are commonly used in prestressed concrete dam concrete slip form construction concrete and fluidized concrete.
to-use liquid admixture for producing more uniform and predictable quality concrete. Placing and finishing requirements are facilitated because this admixture retards setting time. Pozzolith 100 XR admixture meets ASTM C 494 C 494M requirements for Type B retarding and Type D water- reducing and retarding admixtures. Applications
Deccription Water reducing amp retarding plasticiser for concrete. Specification ASTM C 494 - Type B amp D IS 9103 1999. Features Uses Significantly increase or extend workability therefore easing placing To reduce water content and increase compressive strength. To effect cement economies.
Concrete setting retarder ASTM C-494 Type B. Increases setting time of concrete delays setting and improves its workability and its physical properties. Enables delivery of ready-mixed concrete to longer distances. Certified with the CE marking as set retarding concrete admixture according to EN 934-2T8 certificate number 0906-CPD-02412007.
Concrete admixtures also known as concrete additives can improve the performance of concrete. They are added to the concrete before or during mixing. As the most professional manufacturer of construction chemicals in China Kingsun company always offers high-quality concrete chemicals and excellent services for our customers all over the world.
Certain admixtures such as pigments expansive agents and pumping aids are used only in extremely small amounts and are usually batched by hand from premeasured containers. The effectiveness of an admixture depends on several factors including type and amount of cement water content mixing time slump and temperatures of the concrete and air.
