Use of Water Reducers, Retarders, and Superplasticizer

Water reducers, retarders, and superplasticizers are admixtures for concrete, which are added in order to reduce the water content in a mixture or to slow the setting rate of the concrete while retaining the flowing properties of a concrete mixture. Admixtures are used to modify the properties of concrete or mortar to make them more suitable to

Comparing the effects of a retarder and accelerator on

Mar 01, 2020 The properties of the recycled gypsum waste, commercial plaster, and a mixture of waste with commercial plaster were compared. It was demonstrated that except density other properties such as setting time, water content to normal consistency and compressive strength had a direct dependency to content of recycled plaster in the mixture [ 20 ].

Retarders for Rubber Cures Akrochem Corporation

retarders These retarders have structures similar to the sulfenamide class of accelerators. They tend to be more effective retarders and are often used at lower levels than acid retarders. However, the sulfenamide (SFA) retarders cost more; thus, a cost/performance consideration must be made when choosing a retarder.

Retarder Principles Meadowlark

Quartz retarders are sometimes preferred for their durability and high transmission properties. Retarders are used in applications where control or analysis of polarization states is required. Our retarder products include innovative polymer and liquid crystal materials as well as commonly used quartz. Other crystalline materials such as
